RIDGID is taking PEX expansion to the next level with the all-new RIDGID RPE100 PEX Expander. This 12V cordless tool features an industry-first AutoReturn mechanism and a high-efficiency brushless motor — built for plumbers who need to make more connections in less time, without sacrificing a clean, reliable fit.
Engineered for versatility and speed, the RPE100 supports interchangeable expander heads for 3/8" to 1" PEX Type-A tubing, making it a single-tool solution for your full range of rough-in work.
Industry-first AutoReturn — faster connections, fewer steps
The RPE100's AutoReturn feature automatically returns the expander heads to the closed position after every expansion, eliminating manual resets and preventing heads from being accidentally left open. On a large rough-in job, that's one less step on every single connection — and that time adds up fast.
Combined with the auto-rotating head that ensures even, uniform expansion across all PEX Type-A fittings, the RPE100 minimizes rework and reduces the errors that lead to costly callbacks.
Brushless motor for maximum productivity
A high-efficiency brushless motor drives rapid PEX expansions so you can make more connections in less time. Brushless motors run cooler and last longer than brushed alternatives, which means less downtime and lower maintenance costs over the life of the tool.
The RPE100 runs on a 12V battery platform, keeping the tool compact and lightweight at just 4.2 lbs. — easy to move between rooms and levels without fatigue.
Built for tight spaces and all-day use
At 11.2" long and 4.2 lbs., the RPE100 is designed for one-handed operation in the confined spaces where PEX rough-in actually happens. The fully functioning paddle trigger gives you confident control at any angle, and a dual-press startup prevents accidental activations when moving around the jobsite.
A built-in belt hook keeps the tool accessible and off the floor between connections, and the LED work light illuminates your workspace in crawl spaces, wall cavities, and under-sink areas where visibility is limited.
Smart indicators to protect the tool
The RPE100 includes built-in LED maintenance indicators that alert you when the tool needs lubrication or is approaching an overheat condition — so you can stay ahead of service needs and extend tool longevity on every job.

Compatible expander heads & accessories
Note: The RPE100 is compatible with PEX-A tubing only. It is not compatible with PEX-B or PEX-C tubing. Expander heads are sold separately unless purchasing the 80703 Tool Kit, which includes 1/2", 3/4", and 1" heads. Regular lubrication with RIDGID expander head cone grease (81008) is required to maintain tool performance and trigger the maintenance indicator reset.
