Two tools from each brand: one for ⅜ to 1 in., one that reaches 1½ in. All four picks named the genuine model and were new and in stock when I checked on Oct 21, 2026. Prices come from Amazon with the time they were read.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon.com at the time of purchase will apply to the purchase of this product.
What size PEX each tool expands
Size splits these four into two pairs before anything else. The DCE400 and M12 2532 stop at 1 in. The DCE410 and M18 2632 go to 1½ in. Pick your pair first, then compare inside it.
From DeWalt manuals N501295 (DCE400) and NA590873 (DCE410) and Milwaukee manuals 58-14-2532 and 58-14-2635, read Oct 19, 2026. The darker bar on the two big tools marks the 1 to 1½ in. range only they cover.

Buy it if
You expand ½, ¾ and 1 in. PEX-A for repipes, water heaters and fixture runs, and you want one box with everything in it. You own DeWalt 20V packs, or no packs at all.
Skip it if
You’re already on M12 batteries, or you need 1¼ in. Look at the Milwaukee M12 2532 or the DeWalt DCE410.
The DCE400 is DeWalt’s 20V MAX PEX expander for ⅜ to 1 in. tubing. This kit, DCE400D2, holds the tool, ½, ¾ and 1 in. heads (DCE40012, DCE40034 and DCE4001), a tube of DCE400GR grease, two DCB203 2.0Ah batteries, a charger and a kit box. The Amazon listing title names the DCE400D2 kit.
The head rule is the reason it’s the top pick. DeWalt’s product page says the tool uses DeWalt heads and is compatible with Milwaukee and Uponor heads. If you inherit a bag of ProPEX heads from another tool, DeWalt says they’ll thread on. Milwaukee makes no such promise for its own tools, as the head chart below shows.
DeWalt’s manual limits the DCE400 to PEX-A, the expansion-type tubing Uponor’s ProPEX system uses. It says not to expand tubing past the tool’s 1 in. capacity. Each expansion, the head expands, retracts and turns slightly, and the manual tells you to hold the ring and tubing so they don’t turn with it.
The manual’s expansion counts with a ring are 6 to 7 at ⅜ in., 7 to 8 at ½ in., 11 to 12 at ¾ in. and 17 to 18 at 1 in. Milwaukee’s M12 manual gives 5 to 8 at ½ in. and 12 to 18 at 1 in. Both brands say the count changes with weather and technique.
DeWalt calls the DCE400 the fastest PEX expander on the market. The footnote says that’s against a competitive average on ½, ¾ and 1 in. PEX-A, not against a named tool. Milwaukee makes its own fastest claim for the 2532. The speed section below lays both claims side by side.
DeWalt lists the tool at 3.9 lb. DeWalt lists full-trigger actuation, built for tight spaces like a joist bay. An LED lights the head, hang hooks sit on both sides, and a rubber overmold covers the grip.
The warranty is DeWalt’s 3-year limited warranty, plus one year of free service and a 90-day satisfaction guarantee. Milwaukee gives its expanders 5 years on the tool. If you plan to keep one tool for a decade, that gap is real.
My call: for most people buying their first cordless expander, this is the kit to get. It covers the sizes in a house, it comes ready to work, and it takes Milwaukee and Uponor heads too, per DeWalt.

Buy it if
You already carry M12 drivers, lights or a press tool, and you want one battery line. You work through winter and want Milwaukee’s RAPID SEAL heads.
Skip it if
You own no M12 packs and want everything in one box from Amazon. The DeWalt DCE400D2 is the easier buy.
The 2532 is Milwaukee’s M12 FUEL ProPEX expander, built for ⅜ to 1 in. Two versions are linked here. The 2532-20 has the tool, ½, ¾ and 1 in. RAPID SEAL heads (49-16-2414, 2416 and 2418), grease and a case. The 2532-22 kit adds two CP2.0 batteries and a charger.
The battery line is the reason to buy it. Milwaukee says the tool works with all M12 batteries. If your truck already has M12 packs for an impact driver or a press tool, the expander shares them, and the 2532-20 costs you no second charger.
Milwaukee claims the fastest ⅜ to 1 in. expansions and up to 35% faster connections. With RAPID SEAL heads it claims up to 65% faster sealing at 45 degrees. That second number is about how fast the PEX shrinks back onto the fitting in cold weather, which shortens the wait before a pressure test.
The manual is strict about heads. It says to use only Milwaukee M12 ProPEX heads or Uponor Standard heads. Uponor Standard heads won’t rotate on their own on this tool, so you turn the tubing ⅛ turn between expansions. Skip that, and Milwaukee warns of deep grooves and faulty joints.
Its expansion counts with a ring are 6 to 10 at ⅜ in., 5 to 8 at ½ in., 7 to 12 at ¾ in. and 12 to 18 at 1 in. The manual rates the tool for 0 to 125°F. Below 40°F it calls for a longer contraction time, and it rules out connections under 5°F.
Milwaukee lists the tool at 4.54 lb, 7.28 in. long and 11.73 in. tall. That’s heavier than DeWalt’s 3.9 lb listing, but the two makers may not weigh them the same way, so I wouldn’t decide on half a pound. Milwaukee lists an extended dual-actuating trigger for reach in tight spots, and an LED lights the head.
Warranty is 5 years on the tool and 2 years on the battery. On Oct 21, 2026 both linked 2532 listings came from resellers, not Amazon.com. Both titles name the genuine 2532 model.
My call: buy the 2532 only if you’re already on M12. If your batteries are red, it fits the rest of your bag. If they aren’t, the DeWalt kit gets you to the same sizes with batteries included.

Buy it if
You run 1¼ and 1½ in. PEX-A mains or risers, and your packs are DeWalt 20V. You already own DCE400 heads for the small sizes.
Skip it if
Nothing you do goes past 1 in. The DCE400 is about half the weight and covers it.
The DCE410 is DeWalt’s 20V MAX XR expander for ⅜ to 1½ in. This kit, DCE410P1, holds the tool, 1, 1¼ and 1½ in. heads (DCE410100, DCE410114 and DCE410112), DCE400GR grease and one DCB205 5Ah battery. DeWalt’s kit list doesn’t name a charger, so plan on one if you have none.
DeWalt’s manual rates it for ASTM F1960 PEX-A and PEX-B, up to 1½ in. with walls up to 1/6 in. The DCE400 manual says PEX-A only. So if your job uses an F1960 PEX-B, the DCE410 is the DeWalt that lists it.
Heads carry over. DeWalt says the DCE410 works with its existing ⅜ to 1 in. heads, the same ones the DCE400 uses. A shop with a DCE400 can add a DCE410 for the big sizes and keep one set of small heads.
The manual shows why the big 1 in. head matters. With the small DCE4001 head, 1 in. PEX takes about 20 expansions. With the DCE410100 head, it takes 7 to 8. The 1¼ in. head takes 9 to 10, and the 1½ in. head 8 to 9.
DeWalt says the DCE410 is up to 20% faster than Milwaukee’s 2632 M18 expander. Its footnote says that’s the bare tool on a DCB205 pack against the 2632 on a 48-11-1850 XC5.0 pack, on 1½ in. PEX-A. It’s DeWalt’s own test, and Milwaukee doesn’t publish a reply.
DeWalt also claims up to 81 expansions of 1½ in. PEX-A per charge on a 5Ah pack. It calls the tool the lightest cordless pro-grade option for 1¼ and 1½ in. The listed weight is 7.7 lb, against Milwaukee’s 7.1 to 7.19 lb for the 2632, so that claim depends on how each maker weighs.
The body has an upper grip and a lower grip, so you can reach a fitting over your head with two hands. It has a brushless motor and a pocket for DeWalt’s Tool Connect tag. Cold rules match the DCE400: longer contraction under 40°F, and no connections under 5°F.
My call: if your packs are yellow and you run 1¼ or 1½ in., this is the tool. It also takes your DCE400 heads, so a ⅜ to 1 in. head set you already own still works.

Buy it if
You run 1¼ and 1½ in. ProPEX and your truck is on M18. You already own M12 ProPEX heads and want them on the big tool too.
Skip it if
You never go past 1 in. The M12 2532 is about 2.5 lb lighter and covers it.
The 2632 is Milwaukee’s M18 ProPEX expansion tool for ⅜ to 1½ in. This kit, 2632-22XC, holds the tool, 1, 1¼ and 1½ in. ProPEX heads, grease, two M18 REDLITHIUM XC batteries, an M18 and M12 charger and a case, per Milwaukee’s page. The Amazon listing title names the 2632-22XC.
Its head list is the widest of the four. Milwaukee’s manual lists M12 ProPEX heads from ⅜ to 1 in., M18 ProPEX heads from ⅜ to 1½ in., Uponor Standard heads and Uponor H heads. So a crew with an M12 2532 can move its small heads to the 2632, which DeWalt’s big tool doesn’t promise for Milwaukee heads.
The manual’s counts show the same big head effect as DeWalt’s. With a standard 1 in. head, 1 in. PEX takes 19 expansions. With the 1 in. H head, it takes 7. The 1¼ in. H head takes 9 and the 1½ in. H head 10.
It also tells you to expand 1 to 4 more times once the tubing sits flush with the head’s shoulder, and the warmer the room, the more you need. DeWalt’s manuals don’t spell out that step. Uponor Standard heads won’t auto-rotate on the 2632, so with those you turn the tubing ⅛ turn each time.
Milwaukee lists 45 strokes a minute, a 25 mm stroke and a weight of 7.1 to 7.19 lb, 9.5 in. long and 11.8 in. tall. It has a D-handle, a magnesium frame, all-metal gears and an LED. It isn’t a FUEL tool, and Milwaukee doesn’t list a brushless motor for it.
Speed is DeWalt’s attack point. DeWalt says its DCE410 is up to 20% faster than this tool on 1½ in. PEX-A. Milwaukee’s page says the 2632 makes installations faster than other tools, without naming one. Neither claim is an independent test.
Warranty is 5 years on the tool and 3 years on the batteries, per Milwaukee’s kit page. The cold rules match the M12: longer contraction under 40°F, no connections under 5°F, and an operating range of 0 to 125°F.
My call: if your truck is M18 and you run 1¼ or 1½ in. ProPEX, buy this. On Oct 21, 2026 the listing came from a reseller, Stevie’s Tool Garage, so watch the price box. If it’s gone, the DCE410 is the match on yellow packs.

“Ahead” means ahead on that one check, not overall. Weights are each maker’s listed figure. Neither maker says on its page whether that includes a battery.
Which heads fit which expander
A Reddit thread and a Garage Journal post in Google’s results both say the heads swap freely. The makers’ own papers say something narrower. Here’s each tool against each head family.

From DeWalt’s DCE400 and DCE410 product pages and manuals, and Milwaukee manuals 58-14-2532 and 58-14-2635, read Oct 19, 2026. “Not listed” or “not stated” means the maker’s papers don’t cover that pair. It isn’t a ban, but nothing on paper backs it.
DeWalt is the open one. Its DCE400 page says the tool uses DeWalt heads and is compatible with Milwaukee and Uponor heads. It doesn’t say whether that means M12 or M18 heads, so I’d read it as the ⅜ to 1 in. sizes the tool can reach.
Milwaukee is the closed one. The M12 manual says to use only Milwaukee M12 ProPEX heads or Uponor Standard heads. The M18 manual lists M12 and M18 ProPEX heads plus Uponor Standard and H heads. Neither lists DeWalt heads.
One more wrinkle catches people. DeWalt’s head pages call its heads “backward compatible with Milwaukee ProPEX heads” without naming a tool. That isn’t the same as Milwaukee approving them on a Milwaukee expander. If you put DeWalt heads on a Milwaukee tool, you’re outside Milwaukee’s manual.
So the low-risk path is simple. Moving Milwaukee or Uponor heads onto a DeWalt DCE400 has DeWalt’s word behind it. Moving DeWalt heads onto Milwaukee doesn’t have Milwaukee’s.
Auto-rotate depends on the head, not just the tool
Remove the battery before changing expander heads. Keep fingers clear of the cone and head during use; the closing head can pinch. All four tools auto-rotate between expansions, but Milwaukee’s manuals note exceptions for certain heads.

The ⅛ turn matters. Milwaukee’s manuals say skipping it can leave deep grooves inside the tubing and faulty connections. Its troubleshooting list says that if you forgot to rotate, cut 2 in. off the tubing and start over.
Both brands also cap the gap between the tubing and the fitting shoulder at 1/16 in. Past that, cut 2 in. off and start again with a new ring. DeWalt’s DCE410 manual says 2⅗ in. for tubing over 1 in.
What each brand’s speed claim measures
A TOOL TECHNICAL video in Google’s results times Milwaukee ahead on 1 in. pipe. Both makers’ pages print their own speed claims. None of these is an independent lab test, so here’s exactly what each one compares.

Claims quoted from dewalt.com and milwaukeetool.com product pages, read Oct 19, 2026. Footnote details are DeWalt’s.
In the 1 in. class, both tools claim fastest against different baselines, so the two claims can both be true. In the 1½ in. class, only DeWalt names its rival, and it names the 2632.
Speed per expansion matters less than the count. At 1 in., a big-cone head cuts the count from about 19 or 20 to 7 or 8 on both brands’ big tools. That saves more time than any percentage on these pages.
Expansions per 1 in. joint, by tool and head
Each manual prints a recommended number of expansions per size. At 1 in., the head you use changes the count more than the brand does.

For the small sizes, the brands land in the same place. The M12’s ranges are wider because Milwaukee prints one range per size for all conditions. DeWalt prints a tighter range and a note that weather and technique change it.

Batteries and what’s in each kit
One Reddit answer in the results picks DeWalt for its full-size batteries. The bigger question is which packs you already own, because a tool-only expander can use the compatible packs and charger you already own.

DeWalt’s 20V MAX packs fit both of its expanders, so a shop can buy one DCE400D2 kit and later add a bare DCE410 that runs on the same batteries. Milwaukee splits its two expanders across M12 and M18, two different battery lines.
That split cuts both ways. The M12 2532 is lighter in the hand on small pipe. But going to 1½ in. on Milwaukee means M18 packs, while DeWalt keeps you on one battery line.
The 2632-22XC kit includes a charger that takes both M18 and M12 packs. If you already run an M12 2532, that charger covers both tools on the truck.
DeWalt’s DCE410 runtime figure, up to 81 expansions of 1½ in. PEX-A on a 5Ah pack, is the only per-charge number either maker prints for these four tools. Milwaukee doesn’t list expansions per charge on the pages I read.
Listed weight and size
Weight matters most when you expand overhead in a basement ceiling. Here’s what each maker lists.
Longer bar means heavier. From dewalt.com and milwaukeetool.com, read Oct 19, 2026. Neither maker says on these pages whether a battery is included, so treat small gaps with care.
In the small class, DeWalt lists 3.9 lb and Milwaukee 4.54 lb. Milwaukee calls the 2532 a compact right-angle design for one-handed use, 7.28 in. long and 11.73 in. tall.
In the big class, the 2632 at 7.1 to 7.19 lb lists lighter than the DCE410 at 7.7 lb. DeWalt still calls the DCE410 the lightest pro-grade cordless option for 1¼ and 1½ in. Those two statements can’t both hold unless the makers weigh differently.

DeWalt from its DCE400 manual and product page; Milwaukee from its 2532-20 and 2632-22XC pages, read Oct 19, 2026. DeWalt’s warranty excludes normal wear and abuse.
Expander cones and heads wear, and both makers treat them as parts. Milwaukee’s troubleshooting list sends a bent or damaged cone back to a Milwaukee service center. DeWalt’s manual says it will maintain the tool and replace parts worn by normal use, free, for the first year.
On a tool you’ll run for years, the extra two years of Milwaukee cover count for more than the first-year service.

The shared rules come from the PEX system, not the tool. Uponor’s ProPEX joint relies on the tubing shrinking back onto the fitting, and cold slows that. RAPID SEAL heads are Milwaukee’s answer to the wait, and DeWalt lists no matching head.
It depends on your batteries and sizes. For ⅜ to 1 in., the DeWalt DCE400D2 comes with batteries and three heads and takes Milwaukee and Uponor heads, per DeWalt. The Milwaukee M12 2532 has a 5-year warranty and RAPID SEAL heads, and it’s the better buy if you’re already on M12.
Do DeWalt PEX expander heads fit Milwaukee tools?
Milwaukee doesn’t list them. Its M12 manual says to use only Milwaukee M12 ProPEX heads or Uponor Standard heads, and its M18 manual lists Milwaukee and Uponor heads only. DeWalt’s head pages say “backward compatible with Milwaukee ProPEX heads” without naming a tool.
Do Milwaukee heads fit the DeWalt DCE400?
Yes, per DeWalt. Its DCE400 page says the tool uses DeWalt heads and is compatible with Milwaukee and Uponor heads.
Can the DeWalt DCE410 use DCE400 heads?
Yes. DeWalt says the DCE410 works with its existing ⅜ to 1 in. expansion heads. With the small DCE4001 head, a 1 in. joint takes about 20 expansions; with the DCE410100 head it takes 7 to 8.
Does the DeWalt DCE400 work on PEX-B?
DeWalt’s DCE400 manual says PEX-A only. The DCE410 manual lists ASTM F1960 PEX-A and PEX-B.
Do Uponor heads auto-rotate on the Milwaukee M12 2532?
No. Milwaukee’s manual says Uponor Standard heads won’t rotate on their own on the 2532, so you turn the tubing ⅛ turn after each expansion.
Is Milwaukee higher quality than DeWalt?
Neither maker publishes failure rates, so I can’t rank build quality. On paper, Milwaukee gives 5 years on the expander against DeWalt’s 3, and DeWalt adds one year of free service.
Do plumbers prefer DeWalt or Milwaukee PEX expanders?
No published survey answers that. Milwaukee says its expanders are designed for Uponor ProPEX, and DeWalt says its DCE400 takes Milwaukee and Uponor heads. Most buyers should pick by the batteries they already own.
Which is faster, DeWalt or Milwaukee?
Each maker claims its tool is fastest against a different baseline. DeWalt says the DCE410 is up to 20% faster than Milwaukee’s 2632 on 1½ in. PEX-A, in its own test.
What is the best PEX expansion tool?
For most people doing ⅜ to 1 in. work, my call is the DeWalt DCE400D2 kit. Our best PEX expansion tool guide compares more brands, including manual tools.
How I compared them
Why trust me
I’m Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711). The facts on this page come from DeWalt’s and Milwaukee’s own manuals and product pages, not from tests of my own. Where a maker makes a claim, I say whose claim it is.
How I compare
Only what DeWalt, Milwaukee and the Amazon listings publish, read Oct 19, 2026.
A spec score from four published checks (sizes, heads, warranty, weight), shown below. It’s a guide, and the head chart still decides fit.

The spec score, check by check
Every tool gets the same four checks, each worth a quarter, using only the maker facts in the tables above: the pipe sizes it expands, how many head families the maker says fit it, the tool warranty and the listed weight. The score compares published specs. It doesn’t replace the head chart: the right tool is still the one that fits your pipe and your batteries.
