An automatic rotating head helps to ensure even expansion. The bright onboard LED work light and full trigger actuation make it an excellent tool in dimly lit, tight spaces. Carry this tool conveniently around the jobsite with a dual-sided hang hook and belt hook. Rubber overmold on the handle provides an ergonomic grip to keep you comfortable all day. This DEWALT pex expander tool uses DEWALT PEX Heads, and it is compatible with leading competitive PEX heads. Review: Well worth it. - Great tool. Little heavier than expected. Makes short work of installs Review: The only tool for PEX-A expansion - This tool is awesome. It works great and is fast. The tool comes with expansion heads for 1/2, 3/4, and 1 inch pex fittings. This kit has no battery or charger and since there were Dewalt batteries in my shop it made sense to get the bare tool. Plumbed an entire utility room with a pex manifold only took about 2 hours and would have been an all day job in copper. The hand operated tool is good for a here and there but not as good for 50 connections on a full re-plumbing job and this power expansion tool makes this job seem way too easy. Thats a good thing. Be sure to keep the cone portion of the tool clean and lubed with the special lubricant which comes in the tube. Remove the expansion head and clean the inside of the expansion head and the cone and apply lube. If you use too much lubricant then it will seep through the expansion head and get inside the pex tubing which does not seem to be an issue. Just wipe off the expansion head of the excess and keep working. Too little lubricant would shorten the life of the expansion head. It also has a hook that you can mount on either side and the head comes with a hook already. The hook on the head seemed a bit unhandy to use and preferred to use the hook mounted at the battery end of the tool and it made for a more natural grip when reaching for the tool when hung on your tool belt. Milwaukee makes a tool and seems like the head of the tools are identical. One may directly compare the two and for my use it made more sense to maintain battery compatibility. ## Features - The pex tool expands 3/8-inch - 1-inch Pex Type-A tubing - The pex expander tool has an automatic rotating head action for even expansion - The pex expansion tool comes with full trigger actuation for use in tight spaces - Bright LED work light to help illuminate dark areas - Dual-sided hang and belt hooks for convenient storage - Rubber overmold for comfortable, ergonomic grip - Uses DEWALT PEX Heads.

Lasted through many many Jobs *by N***J on March 6, 2026* I cant recommend this enough to people who are considering this. This tool outlasted my initial uses for it and has come in handy many times over afterwards in helping other people too. I did end up with a small issue with battery holding onto the item after so much use but it does not impact the use or speed once you secure the battery by any means. ## Frequently Bought Together - DEWALT DCE400B 20V MAX* 1" PEX Expander Tool (Tool Only) - (Pack of 100) EFIELD 1/2 Inch F1960 Expansion Rings/Sleeves for Pex A Piping System - Vigolix Pex A Fittings –1/2" inch Pex Fittings Set | Elbow, Tee & Coupler Kit | ASTM F1960 Certified PPSU | For Water Supply & Radiant Heating [Pack of 30] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/53947546-dewalt-dce400b-20v-max-1-pex-expander-tool-tool-only](https://www.desertcart.hr/products/53947546-dewalt-dce400b-20v-max-1-pex-expander-tool-tool-only) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-29*
