Best caulk gun

The ETS3000 is the gun I’d keep in the truck, and I’ve used it. It scored a perfect 10 on our checks.

Dripless rates it 18:1, its professional grade. Its thrust ratio page lists 18:1 for the ETS3000 and says construction adhesives and polyurethanes need 18:1 to 26:1 guns. So this one handles the heavy tubes too, not just silicone.

The switch is the reason it wins for plumbing. Dripless says to turn the dripless option on for acrylic and silicone caulks, to stop run-on and get a smooth bead, and off for thick adhesives and polyurethanes, to keep steady pressure on the cartridge. That’s the right behavior for both jobs.

Dripless lists an engineered ergonomic build, a rotating barrel, rugged composite construction, a reinforced cage for extra strength, and a sharp cutter with an extra-long clean-out rod.

Dripless recommends it for all caulks and construction adhesives, including polyurethanes, concrete, masonry and roofing sealants.

Composite is a choice, not a flaw. It keeps the gun light, and the reinforced cage is what holds the cartridge under 18:1 force. If you work around a lot of dropped tools, the metal SI300 or Albion B12 may last longer.

The Amazon listing is model ETS3000 with an 18:1 ratio and a revolving carriage, which matches Dripless. A 10.

The extra-long clean-out rod matters more than it sounds. Dripless lists it on both its composite guns. Hardened silicone in a nozzle is the usual reason a gun gets thrown in the truck bin half full; a long rod pushes the plug out so the next tube starts clean.

How I set it up on a tub: drip-stop on, the tube tip cut small at an angle with the built-in cutter, and the barrel turned so the nozzle follows the corner as I walk the bead around. That’s advice from the trade, not a test, and it works the same with any of these guns.

My call: one gun for the tub surround and the subfloor glue. Leave the drip-stop on for silicone and you won’t chase a bead across the tile.

The Albion B12 is the pro’s smooth-rod gun, and I’ve used it. Albion makes nothing but dispensing tools. It scored 9.0.

Albion publishes numbers the others don’t: a 12:1 mechanical advantage, 375 pounds of thrust and 120 psi. It weighs 1.8 pounds and has a metal half-barrel that rotates to follow the joint.

Albion says it’s designed for all standard viscosity materials in 1/10 gallon or 300 ml cartridges: silicones, acrylics and polyurethane. For thicker material and cold weather, Albion sells the B26 with a 26:1 drive, 900 pounds of thrust and 300 psi.

It has a built-in cartridge puncture wire and a ladder hook. Albion sells a gripping plate and spring kit, 873-40, for all B12 guns, so a worn drive can be rebuilt.

It lost points on drip control. Albion’s page doesn’t list a drip-stop feature, a 5. You’ll pull the rod back with your thumb at the end of a bead.

Albion’s warranty covers defects in material and workmanship with repair or replacement, excluding normal wear, abuse and misuse. It doesn’t give a term in years for manual guns.

The Amazon listing is model B12 with the same 375 lbf and 120 psi figures, sold by Amazon. A 10.

Albion lists the B12’s shipping size as 14 by 9 by 2 inches and its country of origin as Taiwan. The brand’s Amazon text adds Albion’s Double-Gripping Plate technology, which it says doubles the life of the tool; the gripping plates are what grab the rod, and they’re the part the 873-40 kit replaces.

If you’re choosing inside Albion’s line, the B12 and B26 share the same handle and half-barrel. The only difference that matters is the drive: 12:1 for silicone and standard sealants, 26:1 and 900 pounds of thrust for cold or two-part material.

My call: the gun to buy if you want metal and a rebuild kit, and you’re used to thumbing the rod back.

The ETS2000 is Dripless’s best-known gun, the yellow one, and I’ve used it. It scored 8.7.

Dripless lists it at 12:1 on its thrust ratio page, in the same band it uses for contractor work. For silicone and acrylic, that’s plenty.

Weight is its strength. Dripless says it’s 40% lighter than metal models with similar features, and that the lighter weight and ergonomic trigger reduce hand fatigue. The cutter is built into the trigger handle: put the cartridge tip in and pull.

Dripless lists rugged composite construction, an engineered ergonomic grip, a rotating barrel, an extra-long clean-out rod and an easy-clean surface.

It lost points on drip control and frame. Dripless’s ETS2000 page doesn’t list a drip-stop switch, a 5. The brand’s Amazon text says the gun retracts after each pull to prevent dripping, but we score the maker page. Its frame is plain composite with no reinforced cage, an 8.

The Amazon listing is titled ETS2000 with a 12:1 ratio, matching Dripless, though the item data carries a different internal model code. We scored the title match, a 10.

Dripless calls it the painters’ favorite, and the reason shows in the spec list: everything on it is about less effort per tube, not more force. Its thrust ratio page puts the ETS2000 in the 12:1 group with the SH111, the top of its DIY range and the bottom of its contractor range.

It shares the ETS3000’s handle family and rotating barrel, so if you later need 18:1 for adhesive, the step up feels the same in your hand. On a bathroom job where you run a tub, a sink and a backsplash in one go, the lighter gun is the one your wrist will thank you for.

My call: the gun to hand a homeowner who caulks a tub once a year, or to keep in the bathroom-remodel bucket.

The SI300 is Dripless’s heavy duty metal gun, and I’ve used it. It scored 8.3.

Dripless calls it its enhanced-power smooth rod gun: a 10 ounce heavy duty metal tool with an 18:1 thrust ratio for thicker materials. It has the same drip/dripless switch as the ETS3000 for thin or thick materials, and a rotating barrel.

Dripless recommends it for thick silicones, polyurethane adhesives, construction and manufacturing, and says it’s substantial and great for heavy duty jobs.

It lost points on two checks. Dripless’s SI300 page doesn’t mention a cutter or puncture wire, a 5, so carry a utility knife. And the Amazon listing is titled “Contractor Grade Heavy Duty Caulking Gun” with an internal model code rather than SI300. Its description, metal, drip switch and rotating frame, matches the SI300, but the name doesn’t, a 5.

Stock was thin on Oct 23: eight left, from a paint supply seller. If it runs out, the card shows no price; the ETS3000 is the same 18:1 with a cutter.

The switch works like the ETS3000’s. Dripless says the drip/dripless toggle is for gunning thin or thick materials: on for silicone, so the rod backs off when you let go, off for heavy adhesive, so pressure stays on the tube.

Dripless builds the same 18:1 metal design in bigger sizes, the SI500 and SI600, and a 26:1 HR300 for even thicker material. The SI300 is the one for standard 10 ounce cartridges, the size every plumbing silicone comes in.

Being metal, it’s heavier than the composite guns; Dripless calls it substantial. On a long day of gunning that weight adds up, which is the main reason I’d still put the ETS3000 first for most plumbers.

My call: the metal version of the ETS3000 for crews who are hard on tools. For most plumbers the ETS3000 does the same job lighter.
