When you are making PEX connections all day, even one extra step can slow things down. That is where the new RIDGID RPE 100 PEX Expander Kit (RD80703) stands out.

Built for professionals working with PEX Type-A tubing, this cordless expander is designed to make each connection faster, more consistent, and easier to complete. With features like an automatic head reset, fast brushless motor, auto-rotating expander heads, and a compact one-handed design, the RPE 100 helps take some of the frustration out of repetitive PEX work.


What Is the RIDGID RPE 100 PEX Expander?

The RIDGID RPE 100 (RD80763) is a cordless PEX expansion tool made for installing PEX Type-A tubing and fittings. It works by expanding the end of the tubing so a fitting can be inserted. As the tubing returns to its original shape, it tightens around the fitting to create a secure connection.

The tool supports interchangeable expander heads for tubing sizes from 3/8 inch through 1 inch, making it useful for everything from residential plumbing repairs to larger installation projects.

AutoReturn Eliminates a Repetitive Step

One of the biggest highlights of the RPE 100 is RIDGID’s industry-first AutoReturn feature.

After the expansion is complete, the tool automatically returns the expander head to its closed position. That means you do not have to manually reset the head before moving on to the next connection.

It may sound like a small improvement, but when you are making connection after connection, it can save a noticeable amount of time. It also helps prevent the expander head from being left open between uses.

The result is a smoother workflow with fewer steps to think about.


Faster Expansions Mean More Connections

The RPE 100 uses a high-efficiency brushless motor to deliver quick, repeatable expansion cycles.

For professionals handling larger plumbing installations, faster cycles can mean more completed connections throughout the day. Instead of waiting on the tool or dealing with inconsistent performance, users can move from one fitting to the next with less downtime.

The brushless motor is also designed for long-term durability, making the tool a strong choice for contractors who expect to use it regularly.


Automatic Rotation Helps Keep Expansions Even

A good PEX connection starts with a clean, even expansion. If the tubing is expanded unevenly, getting the fitting into place can become more difficult and may lead to rework.

The RIDGID RPE 100 (RD80703) automatically rotates the expander head during use. This helps expand the tubing evenly around the entire opening without requiring the user to manually twist or reposition the tool between cycles.

That automatic rotation helps create more consistent results and gives users greater confidence that each connection is being prepared properly.


One Tool for Multiple PEX Sizes

The RPE 100 works with threaded, interchangeable expander heads for the most common PEX Type-A tubing sizes.

Compatible sizes include:
– 3/8-inch PEX Expander Head (RD80713)
– 1/2-inch PEX Expander Head (RD80723)
– 5/8-inch PEX Expander Head (RD80733)
– 3/4-inch PEX Expander Head (RD80743)
– 1-inch PEX Expander Head
(RD80753)


The threaded design makes it easy to switch between sizes while keeping the head securely attached during operation.

Whether you are working on a small fixture connection or a larger water line, the RPE 100 can be adapted to match the tubing size you need.


RIDGID PEX Expander Heads Are Built for the Jobsite

RIDGID PEX Expander Heads are made from stainless steel to help stand up to demanding jobsite conditions. The material also helps resist corrosion, which is important for accessories that may regularly be exposed to moisture.

Each head has its size clearly etched into the surface, making it easier to grab the correct one without guessing.

The heads are designed for quick changes and work with the tool’s automatic rotation system to create an even expansion across the tubing. This helps reduce mistakes and keeps the process simple, even when switching between different sizes throughout the day.

Compact Enough for Tight Spaces

Plumbing work rarely happens in wide-open spaces. Connections are often tucked inside cabinets, between floor joists, behind fixtures, or inside crowded mechanical rooms.

The compact design of the RIDGID RPE 100 (RD80763) makes it easier to maneuver in those areas. It is built for one-handed operation, which allows the user to hold or position the tubing with the other hand.

A built-in belt hook also keeps the tool close when moving around the jobsite or climbing between work areas.


Paddle Trigger Makes the Tool Easier to Use

The RPE 100 features a fully functioning paddle trigger rather than a small standard trigger.

The larger trigger area makes it easier to activate the tool from different hand positions. That can be especially helpful when working at an awkward angle or when there is not enough room to hold the tool in the usual way.

A dual-press startup helps reduce accidental activation, giving the user more control while positioning the tool around the tubing.


Better Visibility and Easier Maintenance

A built-in LED work light helps illuminate the connection area when working in dark or enclosed spaces. This makes it easier to line up the tool, check the tubing, and confirm that everything is properly positioned before beginning the expansion.

The tool also includes maintenance indicators that help users keep track of its condition. Staying ahead of routine maintenance can help reduce unexpected downtime and extend the working life of the tool.


What Comes in the RIDGID RD80703 Kit?

The RIDGID RPE 100 PEX Expansion Tool Kit (RD80703) is designed to give professionals a complete setup for common PEX Type-A applications.

The kit includes the cordless PEX expansion tool, battery and charging equipment, a carrying case, and expander heads covering tubing sizes from 1/2 inch through 1 inch.

RIDGID also offers other options depending on what you already have:

The bare tool (RD80763) is available for users who only need the expander.

The battery kit (RD80773) includes the tool, battery equipment, accessories, and carrying case

Is the RIDGID RPE 100 Worth It?

The RIDGID RPE 100 is built around the parts of PEX installation that can become repetitive or frustrating.

The AutoReturn feature removes a manual reset step. The automatic head rotation helps create consistent expansions. The brushless motor keeps the tool moving quickly, while the compact design makes it easier to work in tight areas.

With support for 3/8-inch through 1-inch PEX Type-A tubing, the RPE 100 gives professionals one versatile tool for a wide range of plumbing applications.
