Quick answer

Look at your rings first. For copper crimp rings from ⅜ to 1 inch, get the Apollo 69PTKH0015K kit. For stainless clamp rings with an ear, get a clamp tool like SharkBite’s instead. Expansion rings need an expansion tool.

Which ring is on your fittings?

“PEX crimp tool” covers two different tools, and each one closes only its own ring. Look at the band that holds the pipe on the fitting before you buy anything.

Ring types and their standards: ASTM F1807 for copper crimp rings, ASTM F2098 for stainless clamps. Tool and check rules from SharkBite’s install pages and Apollo’s instruction sheets. Expansion fittings are PEX-A only, per SharkBite’s PEX-A guide.
A smooth copper band

That’s a copper crimp ring under ASTM F1807. You need a crimp tool with a jaw for that ring’s size, and you check every joint with a Go/No-Go gauge. Picks 1, 2, 3 and 6 below are this type.

A stainless band with a raised ear

That’s a stainless clamp ring under ASTM F2098, often sold as a cinch or pinch clamp. A clamp tool squeezes the ear shut. SharkBite says one clamp tool fits every clamp from ⅜ to 1 inch. Picks 4 and 5 are this type.

A thick plastic ring over flared pipe

That’s an expansion joint, and SharkBite’s guide says expansion fittings must be used with PEX-A pipe and expansion rings. No crimp tool makes that joint. Our expansion tool guide covers it.

A worm-drive hose clamp

Not a PEX joint. No maker sheet we read lists one. ASTM F2098 describes a stainless clamp deformed and locked around the tubing, and SharkBite says to use only fittings and accessories tested and approved for its system.

Crimp tool or clamp tool: what actually differs

Both rings meet the same pressure and heat rating, so the choice comes down to the tool you’d rather carry and the sizes you run.

  1. 1
    Same rating

    ASTM F1807 covers copper crimp rings for 100 psi water systems at up to and including 180°F. ASTM F2098 is written as an alternative to those rings for the same 100 psi and 180°F.

  2. 2
    Same fittings

    SharkBite says both its brass and poly crimp fittings can be connected with either copper crimp rings or stainless clamp rings. F2098 covers clamps for F1807 or F2159 fittings.

  3. 3
    Different tools

    A copper ring needs a jaw sized to that ring. A clamp tool pinches an ear, so one tool covers ⅜ to 1 inch, per SharkBite and Apollo.

  4. 4
    Different checks

    Copper rings get a Go/No-Go gauge on every joint. SharkBite says a calibrated clamp tool removes the need to gauge each ring; you look for a closed ear instead.

  5. 5
    Different top size

    Copper crimp rings under F1807 run up to 2 inch. The clamp tools on this page stop at 1 inch, so bigger pipe means copper rings among these picks.

No maker or standard we read ranks one ring as more reliable than the other. Pick by the ring your fittings already use, and by how much space you’ll have around the joint.

One cold-weather rule is worth knowing. SharkBite’s PEX-A guide says not to use its brass or poly crimp fittings with stainless clamps on PE-RT pipe at 32°F or less. In those conditions it calls for copper crimp rings.

ASTM F1807 copper rings⅜ to 1 in.Interchangeable jawsGo/No-Go gauge includedAdjustable crimp forceSame kit as 69PTKH0015Q

Buy it if

Your fittings use copper crimp rings and you run more than one size, from ⅜ up to 1 inch.

Skip it if

Your fittings use stainless clamp rings with an ear, or you only ever crimp ½ and ¾ and don’t want to swap jaws.

This is the tool I’d point most people to, because one kit covers every copper crimp ring size you’re likely to find in a house: ⅜, ½, ¾ and 1 inch. Apollo’s crimp tool page lists it as model 69PTKH0015K or 69PTKH0015Q and says the kit comes with the crimp tool, its heads, a Go/No-Go gauge, an adjustment wrench and a plastic carrying case.

Apollo’s page describes four interchangeable heads from ⅜ to 1 inch. Its instruction sheet adds a detail worth knowing before you open the case: for 1-inch rings you crimp with no jaws inserted, because the tool itself is the 1-inch size. The ⅜, ½ and ¾ jaws go in when you need them.

Changing sizes is quick. The sheet says to pull the handles apart to open the jaws fully, slide one jaw into the tool under the pin, and let the magnets click it into place, then repeat with the other jaw. To take one out, pull it down and out.

Apollo notes that jaws can’t be replaced on any of its other crimp tools, so this is the Apollo crimper that changes sizes.

The other reason I like it is the force adjustment. The sheet shows a screw with numbers around it. You open the handle, loosen the nut, push and rotate the screw to a higher number for more crimp force or a lower one for less, and tighten the nut. When the gauge says a ring is off, you have a clear way to correct the tool.

Apollo’s gauge rule is specific. Slide the correct slot around the crimped ring. If the ring won’t enter the slot at all, the crimp is a No-Go, so add force and re-crimp. If it slides all the way in, it’s compressed too small, so remove the ring and reduce force. A good crimp stops in the Go range at least at one point.

Know the limits. It closes copper crimp rings only. Apollo’s page talks about crimping fittings on PEX-B pipe; if your pipe is PEX-A, confirm your fitting maker approves crimp fittings on it, as SharkBite’s guide does for its F1807 fittings. On Oct 21, 2026 the seller was a third-party store, 67 Hardware, with few left.

My call: if you’ll crimp more than one size, this kit is the sensible single purchase. Set the ring ⅛ to ¼ inch from the end of the pipe, over the fitting’s ribs, as Apollo’s sheet shows, and gauge every joint.

Why there’s no dual head ½ and ¾ pick

A dual head crimper puts the ½ and ¾ inch jaws in one head, so there’s nothing to swap in a crawlspace. SharkBite’s crimp tool table lists its orange 23251 dual head as discontinued. Its current one, the blue-handled 24692Z, didn’t come up on Amazon when I searched on Oct 22, 2026.

Until it is, the Apollo kit covers both sizes with a jaw change, and the RIDGID pair below covers them one tool per size.

Whatever crimper you use, gauge every joint. SharkBite says the Go side should slide tightly over the crimped ring and the No-Go side shouldn’t slide over it at all. If neither side fits, the tool needs calibrating.

For SharkBite’s dual head, calibrating takes a ruler. Close the handles gently until the jaws touch and measure between the handles. The right range is 8¼ to 8¾ inches. If it’s off, remove the eccentric set screw, turn the eccentric while you check the width, then tighten the screw and make a test joint.

If a joint fails the gauge, SharkBite says to cut the pipe as close to the fitting as you can. To save the fitting, cut the ring on at least two opposite sides. Our guide to removing a PEX crimp ring walks through it.

Buy it if

You crimp between joists, behind a vanity or inside a wall cavity, where long handles can’t open.

Skip it if

You want one tool for several sizes, or you work in open basements where full-size handles fit.

A full-size crimper needs room to open its handles wide, and the joints that leak are often the ones nobody could reach properly. RIDGID built its close quarters tools for that problem. Its catalog says their handle openings are up to 71% smaller than traditional PEX crimp tools.

The 43853 crimps ½-inch copper rings and the 43858 crimps ¾-inch rings. Both are listed in RIDGID’s catalog for the ASTM F1807 black copper crimp ring system. RIDGID gives the 43853 at 2.0 pounds and the 43858 at 2.3 pounds.

The feature I’d pay for is the gauge. RIDGID’s catalog says the Go/No-Go gauge is built in and folds into the handle, and calls it an exclusive feature of its crimp tools. In a tight spot, a gauge that can’t fall out of your pocket and into the insulation matters.

Calibration is by an adjustable cam, per the catalog. RIDGID’s handles are glass-filled polycarbonate with its E3 grip design. For comparison, RIDGID’s traditional ½-inch crimp tool, the 23448, is listed at 14.3 inches long; its own catalog pitches the close quarters line for maneuvering into tight spaces.

The trade-off is that each tool does one size. If your job has both ½ and ¾ joints in tight spots, you’ll want both. I’ve linked the 43858 as a second button on this card. On Oct 21, 2026 both were new from America Tools, with few left.

The joint itself follows the same rules as any copper ring. Square cut, ring ⅛ to ¼ inch from the end of the pipe so it sits over the barbs, tool square to the fitting, handles fully closed, then gauge it.

My call: if you’re a pro or a serious DIYer fixing joints in finished walls, this is the tool for the hard ones. For open runs in a basement, the dual-head SharkBite or the Apollo kit covers more sizes per tool.

Pros

  • One tool for ⅜ to 1 inch clamps
  • One-hand grip leaves a hand free
  • Won’t release until the clamp is closed
  • Meets ASTM F2098

Cons

  • Stainless clamp rings only
  • Stops at 1 inch
  • Check calibration with the gauge
  • Not for PE-RT in freezing conditions, per SharkBite
ASTM F2098 stainless clamps⅜ to 1 in.Three-handle designGo/No-Go gauge includedAdjustment nut and screwSold by Amazon.com

Buy it if

Your fittings use stainless clamp rings with an ear, or you want one tool for every size up to 1 inch.

Skip it if

Your rings are copper bands, you run pipe larger than 1 inch, or you’re joining PE-RT at 32°F or below.

If the rings on your fittings have a raised ear, this is the tool type you need. SharkBite’s product page says it compresses stainless steel clamp rings to secure PEX or PE-RT tubing to brass or poly crimp fittings, and that one tool works with every clamp size from ⅜ to 1 inch. It meets ASTM F2098.

The three-handle design is the practical draw. SharkBite says it lets you grip the tool with one hand and keep the other free for a flashlight, a ladder or the pipe. SharkBite’s PEX-A guide adds that the tool can’t be removed until the clamp ring is fully compressed.

Making the joint is short. Set the clamp ⅛ to ¼ inch from the end of the pipe so it sits over the barbs, put the open jaws over the raised ear and squeeze until it’s completely compressed. Then SharkBite says to look at the clamp for a correctly closed ear.

SharkBite also says a properly calibrated clamp tool removes the need to gauge each ring. To check calibration, close the handles to the stop and put the gauge in the jaw gap. If it stops at No-Go, you’re set.

If the gauge goes past No-Go, loosen the adjustment nut, set the Go side in the jaws, turn the adjustment screw counterclockwise until the jaws touch it, tighten the nut and make a test joint.

The second button is Apollo’s 69PTKG1096 ratchet clamp tool. Apollo’s sheet says it ratchets until the tool auto-releases, works with Apollo, Watts, Murray and Oetiker clamps, and must not be used with Zurn QickClamp crimp rings. Apollo says its clamp tools are pre-calibrated for up to 10,000 uses, with a jaw gap of 0.8 to 1.2 mm.

One limit is easy to miss. SharkBite’s PEX-A guide says not to use its crimp fittings with stainless clamps on PE-RT pipe at 32°F or less, and to use copper crimp rings then. If you work outdoors in winter on PE-RT, a copper ring tool belongs in the truck too.

My call: if you’re starting fresh and everything you run is 1 inch or smaller, a clamp tool is the simplest way to cover every size. On Oct 21, 2026 the SharkBite was sold by Amazon.com.

ASTM F2098 stainless clamps⅜ to 1 in.11.5 in. longBrace bracket includedGo/No-Go gauge includedImpact under 4,000 RPM

Buy it if

You set a lot of stainless pinch clamps on PEX-B and already own a compatible 18V or 20V impact driver.

Skip it if

Your pipe is PEX-A or PE-RT, your rings are copper, or you make a handful of joints a year.

This attachment turns an impact driver into a powered pinch tool. DEWALT’s manual says the impact driver turns a power screw that mechanically compresses the pinch clamp. Trigger it in forward to close the jaws and in reverse to open them.

DEWALT’s product page claims 6x faster clamps. Its footnote says that’s pinch time only, measured on 1-inch stainless pinch clamps on PEX-B pipe with a DCF845 impact driver, against a competitor’s hand pincher. DEWALT also claims far less pinching effort than a hand tool, and it lists a capacity of ⅜ to 1 inch.

Read the manual’s limits before you buy. It says the attachment installs stainless pinch clamps that meet ASTM F2098, and lists it for use with PEX-B pipe and brass or poly alloy couplings. It’s approved only for impact drivers. DEWALT says not to use it with a drill/driver.

Your driver matters too. The manual calls for an impact driver under 4,000 RPM and under 280 Nm (2,500 in-lb), or a mode below those numbers on a stronger driver. DEWALT’s page lists its optimized drivers and compatible models from other brands, including Milwaukee, Makita and Bosch.

The pinch steps are clear. Open the jaws in reverse until you hear a click, set the clamp ⅛ to ¼ inch from the pipe end per the fitting maker, and secure the tubing. Put the clamp tab in the jaws and run it forward. The crimp is complete at an audible click, when the viewing windows are fully green.

Before any jaw check or calibration, remove the impact driver’s battery. DEWALT requires the included Go/No-Go gauge before and after each clamp. The GO side should go in and the NO-GO side shouldn’t. If either fails, you adjust an eccentric pin inside the housing one number at a time.

DEWALT’s page says it fits a standard joist bay with 360° rotation, includes a brace bracket and gauge, and carries a 3-year limited warranty, 1 year of free service and a 90-day satisfaction guarantee.

My call: for a crew setting dozens of pinch clamps on PEX-B, it earns its place. For one bathroom, the hand clamp tool above does the same job.

ASTM F1807 copper rings1¼, 1½ and 2 in.Multi-head kitGo gauge includedSocket and Allen wrench in kitSpare parts in kit

Buy it if

You’re crimping a water service, a manifold feed or a commercial run in 1¼, 1½ or 2 inch PEX with copper rings.

Skip it if

Your largest pipe is 1 inch. The Apollo kit covers ⅜ to 1 inch, and so do the clamp tools.

Most crimp tools stop at 1 inch, but ASTM F1807 lists copper crimp ring fittings up to 2 inch. For a main line, a manifold feed or a light commercial job, this is the kit among my picks that reaches those sizes.

SharkBite’s crimp tool table lists the 24675 as a multi-head kit for 1¼, 1½ and 2 inch. The Amazon listing says the kit includes the crimp tool, crimp jaws for all three sizes, a go gauge, a socket, an Allen wrench and replacement parts. SharkBite says its crimp tools are factory calibrated and meet ASTM F1807.

Big rings follow the same rules as small ones. SharkBite’s steps: cut the pipe clean and square, set the ring ⅛ or ¼ inch from the fitting shoulder, keep the tool at 90 degrees to the fitting and close the handles completely. Then check the joint with the gauge.

A square cut matters more as the pipe gets bigger. SharkBite’s PEX-A guide says a rough or uneven cut can weaken the joint. On 2-inch pipe, use a cutter rated for that diameter and look at the end before you slide the ring on.

Why not a clamp tool for these sizes? The clamp tools on this page are rated to 1 inch, and ASTM F2098 clamps cover five sizes of fittings. For 1¼ inch and up, copper rings and a tool like this one are the route among my picks.

Be honest about whether you need it. If your largest pipe is 1 inch, the Apollo kit covers every size you’ll touch. This one is for the bigger runs, and on Oct 21, 2026 it was sold by Amazon.com.

SharkBite’s guide has you slide the ring about 2 inches back from the end before you push the pipe onto the fitting, then move it to ⅛ to ¼ inch. On big pipe, set the ring before the fitting goes on, because it won’t go over the fitting afterward.

My call: if you crimp 1¼ to 2 inch copper rings, this kit saves renting or borrowing a tool for every job.

Which tool covers which pipe size

PEX ring sizes match the pipe’s nominal size. Here’s where each pick starts and stops.

The 1-inch row trips people up on the Apollo kit. Its sheet says the tool crimps 1-inch rings with no jaws inserted, so don’t go hunting for a fourth jaw in the case.

Ring sizes also have to match the fitting maker’s system. SharkBite’s guide says to use only fittings and accessories tested and approved for its PEX system, so buy rings that your fitting maker names.

How to read a Go/No-Go gauge the right way

This step tells you whether a copper ring joint is right, and it’s often explained backwards. Here’s what the makers actually say.

What the gauge doesWhat it meansWhat to do
Go slot slides over the ring, No-Go doesn’tGood crimpMove on to the next joint.
Neither slot slides over the ringUnder-crimpedRecalibrate or add force, then re-crimp. SharkBite says the tool isn’t calibrated.
Ring slides all the way into the slotOver-crimpedApollo says the ring is compressed too small. Remove it and reduce force.
Ring stops in the Go range at one point onlyGood, per ApolloApollo says the ring won’t fit the Go range all the way around.

SharkBite: “The Go side of the gauge should tightly slide over the crimp ring connection and the No-Go should not slide over the connection at all.” Apollo’s 69PTKH gauge sheet gives the under and over readings.

  1. 1
    Use the slot for that ring size

    Each gauge has slots per size. Apollo says to slide the correct slot around the crimped ring.

  2. 2
    Check right after you crimp

    SharkBite lists the gauge check as the step after closing the handles. Do it before the joint goes behind drywall.

  3. 3
    Fix a failed joint, don’t re-squeeze blindly

    SharkBite says to cut the pipe close to the fitting, or cut the ring on two opposite sides to save the fitting, then calibrate and start over.

  4. 4
    Gauge the tool, too

    SharkBite’s clamp tool and DEWALT’s attachment check the jaw gap with the gauge. DEWALT says to remove the battery before gauging, before and after each clamp.

How each tool is calibrated

Apollo says its tools may need calibration after repeated use. These are the makers’ own adjustment methods, so you know what you’re signing up for.

ToolHow you check itHow you adjust it
Apollo 69PTKH crimp toolsGauge reading on a crimped ringLoosen the nut, turn the numbered screw up for more force

DEWALT DWAPXPIRRemove battery; GO enters, NO-GO doesn’tWith battery removed, adjust the eccentric pin one number at a time

From Apollo’s 69PTKH and 69PTKG1096 sheets, SharkBite’s two calibration pages, RIDGID’s catalog and DEWALT manual NA504718. Apollo says its clamp tools are pre-calibrated for up to 10,000 uses.

SharkBite claims its crimp tools give ten times more crimps between calibration. Whatever the brand, the gauge is how you find out.

How to make a PEX crimp joint, step by step

The same order works for any copper ring tool here. It comes from SharkBite’s install pages and Apollo’s instruction sheet.

  1. 1
    Cut the pipe square

    SharkBite says to cut as cleanly and squarely as possible, and its PEX-A guide warns a rough or uneven cut can weaken the joint. Our PEX cutter guide covers the cutter.

  2. 2
    Slide the ring on first

    SharkBite’s guide says to slide the ring about 2 inches back from the end before you fit the pipe.

  3. 3
    Push the pipe onto the fitting

    Push until the pipe touches the fitting shoulder. Apollo’s sheet says to insert the fitting until it stops.

  4. 4
    Set the ring ⅛ to ¼ inch from the end

    That puts the ring over the barbs or ribs, per SharkBite and Apollo. Apollo’s drawing shows it over the two end ribs.

  5. 5
    Crimp square to the fitting

    Center the open jaws over the ring, hold the tool at 90 degrees and close the handles completely, per SharkBite.

  6. 6
    Gauge every joint

    Pressure test before you close up

    Apollo’s clamp tool sheet says to pressure test and inspect before burying or normal use, and to redo any joint that leaks.

Do you crimp PEX-A or PEX-B?

Both, depending on the fitting maker. This is the question Google shows most, and the answers differ by brand.

If your pipe and fittings come from different makers, follow the fitting maker’s instructions. DEWALT’s manual says tubing and hardware must follow local codes and the authority having jurisdiction.

Manual or powered: when a battery tool pays off

Hand tools make the same joint. Power is about how many joints you make in a day and how your hands feel after.

RIDGID’s catalog lists ASTM F1807 jaws for its compact press tools in ½, ¾, 1 and 1¼ inch, and says those jaws never require calibration, unlike manual crimp tools. If you already own a RIDGID compact press tool for copper, the jaws may be a better buy than another hand tool. Our press tool guide covers the tools.

How to choose in four questions

Answer these in order and you’ll land on one tool.

QuestionIf yesIf no
Do your rings have an ear?Clamp tool: SharkBite or ApolloCopper ring tool: keep going

Already have stainless clamps, PEX-B and an impact driver, and a whole house to plumb? That’s the DEWALT’s job. Fixing one leaking joint? Match whatever ring is already on it; our guide to a leaking PEX crimp fitting explains the checks.

Common mistakes, and what the makers say instead

Each row pairs a common error with the maker’s rule.

MistakeWhat the sources say
Reading the gauge backwardsGo slides over, No-Go must not, per SharkBite
Ring right at the pipe end⅛ to ¼ in. back, over the barbs, per SharkBite and Apollo
Crimping at an angleKeep the tool at 90° to the fitting, per SharkBite
Never checking calibrationSharkBite and DEWALT both publish gauge checks for the tool

Questions people ask about PEX crimp tools

Is it better to crimp or clamp PEX?

Neither ring is ranked above the other by any maker or standard we read. ASTM F1807 copper rings and F2098 stainless clamps share the same 100 psi and 180°F rating. Clamp tools cover ⅜ to 1 inch with one tool; copper rings reach 2 inch.

What is the best crimp tool for PEX?

For copper crimp rings from ⅜ to 1 inch, the Apollo 69PTKH0015K kit covers every size in one case. For stainless clamp rings, a clamp tool like SharkBite’s 3-handle tool covers ⅜ to 1 inch.

Do you crimp PEX-A or PEX-B?

Both, if the fitting maker allows it. SharkBite’s PEX-A guide approves its F1807 crimp and F2159 clamp fittings on PEX-A, PEX-B and PEX-C. DEWALT’s attachment manual lists PEX-B only.

Can a crimp tool close a stainless clamp ring?

Not a copper-ring crimper with sized jaws. Stainless clamp rings have an ear that a clamp tool pinches shut, and SharkBite sells separate tools for each ring.

Do I need a Go/No-Go gauge?

Yes for copper rings. SharkBite says the Go side should slide tightly over the crimped ring and the No-Go side should not slide over it at all. A calibrated clamp tool removes the need to gauge each ring, per SharkBite.

How far from the end does the ring go?

SharkBite and Apollo both say ⅛ to ¼ inch from the end of the pipe, which puts the ring over the fitting’s barbs or ribs.

How do I calibrate a PEX crimp tool?

It depends on the brand. SharkBite measures the handle gap with the jaws touching, which should be 8¼ to 8¾ inches. Apollo uses a numbered force screw. RIDGID’s close quarters tools use an adjustable cam.

What tool do I need for 2 inch PEX?

A copper ring tool rated for that size, such as the SharkBite 24675 kit for 1¼, 1½ and 2 inch. The clamp tools on this page stop at 1 inch.

Can I use the Apollo clamp tool on Zurn QickClamp rings?

No. Apollo’s 69PTKG1096 sheet says not to use it with Zurn QickClamp PEX crimp rings.

Does the DEWALT pinch attachment work on PEX-A?

DEWALT’s manual lists it for PEX-B pipe with brass or poly alloy couplings, and for stainless pinch clamps that meet ASTM F2098.

Can I use stainless clamps in freezing weather?

Not on PE-RT with SharkBite crimp fittings at 32°F or less. SharkBite’s guide says to use copper crimp rings in those conditions.

How do I fix a crimp that fails the gauge?

SharkBite says to cut the pipe as close to the fitting as you can, or cut the ring on at least two opposite sides to save the fitting, then calibrate the tool and redo the joint.

How I pick and why you can trust it

Why trust me

I’m Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711). Joint steps, gauge readings and calibration here come from Apollo’s, SharkBite’s, RIDGID’s and DEWALT’s own documents and the ASTM standards, all named below.

How I pick

  • Ring type first, then size range, then the job.
  • Only genuine branded tools, new and in stock, checked through Amazon’s Creators API on Oct 19 and again Oct 21, 2026. Third-party listings with one or two left were dropped.
  • Specs from the maker’s page, sheet or catalog first, then the listing.
  • The spec score checks how many ring sizes one tool closes, how you check a joint and whether you need anything else to run it. No maker publishes a test that compares crimp quality, so it isn’t scored.
  • CPSC recall search for PEX crimp tools, PEX clamp tools, SharkBite and DEWALT PEX: none found.

The spec score, check by check

Each tool gets the same three checks, from the makers’ pages, sheets and RIDGID’s catalog, averaged to one decimal. Every pick has to reach 7.0.

Ring type isn’t in the score, because your fittings decide it: copper rings need a crimp tool and stainless clamps need a clamp tool. Every pick is calibrated to its ASTM standard, so crimp quality isn’t scored either. The RIDGID scores lower for doing one size per tool, which is the price of fitting between joists.

Check (weight)How it’s scored
Sizes one tool closes (⅓)10 = four ring sizes from one tool; 8 = three; 6 = one
Joint check (⅓)10 = Go/No-Go gauge in the box or built in; 8 = Go gauge only
Nothing else to buy (⅓)10 = hand tool, works on its own; 7 = needs an impact driver you already own
