Milwaukee ProPEX Expander

Navigating the realm of plumbing installations can be a daunting task, especially when transitioning from traditional methods to newer technologies. Recently, I had the opportunity to work with the Milwaukee ProPEX Expander, model 2532-20, and it has significantly altered my approach to plumbing projects. This tool, designed specifically for PEX (cross-linked polyethylene) installations, has proven to be a robust and reliable asset in my toolkit.

The ProPEX Expander is a cordless, battery-powered tool that facilitates the expansion of PEX pipes ranging from 3/8” to 1”. What immediately stands out is its auto-rotating head, which ensures uniform expansions with minimal effort. This feature is particularly beneficial when working in tight spaces, where maneuverability is often restricted. The right-angle design further enhances accessibility, making it easier to reach confined areas without contorting your body into uncomfortable positions.

One of the most notable aspects of this tool is its build quality. The ProPEX Expander boasts a durable all-metal gear system and a magnesium frame, which not only adds to its longevity but also provides a solid, reassuring feel in hand. Despite its robust construction, the tool is relatively lightweight at 4.54 pounds, striking a balance between durability and ease of use. The extended dual-actuating trigger is another thoughtful addition, allowing for improved reach and control during operation.

In terms of performance, the ProPEX Expander excels. The quick cam mechanism facilitates rapid expansions, significantly reducing the time required for each connection. This efficiency is further enhanced by the LED work light, which illuminates the working area, ensuring precision even in dimly lit spaces. The tool is compatible with all M12 batteries, providing flexibility and convenience for those already invested in Milwaukee’s M12 ecosystem.

During my projects, I found the ProPEX Expander to be incredibly reliable. The auto-rotating head consistently produced even expansions, which is crucial for creating secure, leak-free connections. This consistency is particularly important when working with larger diameter pipes, such as the 1” PEX, where manual methods often fall short. The tool’s ability to handle various pipe sizes with ease makes it a versatile addition to any plumber’s arsenal.

However, the ProPEX Expander is not without its drawbacks. One of the primary concerns is the absence of a PACKOUT compatible case. Given Milwaukee’s extensive range of modular storage solutions, it’s surprising that this tool is supplied with a standard box. For professionals who value organization and portability, this omission is a notable inconvenience. Additionally, the instruction manual is printed on low-quality paper with small type, which may not withstand the rigors of a construction environment. A more durable manual would be a welcome improvement, ensuring that users can reference it for years to come.

Another minor issue is the lack of a 3/8” expander head in the kit, despite the tool being advertised for use with 3/8” PEX. While this may not be a significant concern for everyone, it’s an oversight that could affect those who frequently work with smaller diameter pipes. On the positive side, the kit includes two M12 batteries, a charger, and expander heads for 1/2”, 3/4”, and 1” PEX, along with a tube of grease for maintaining the expander cone heads. This comprehensive package ensures that you have everything needed for most residential plumbing projects right out of the box.

In terms of ergonomics, the ProPEX Expander is well-balanced and comfortable to use. The tool fits nicely in hand, and the extended trigger design allows for easy operation. The LED light is a particularly useful feature, as it provides ample illumination in dark or cramped spaces, enhancing visibility and accuracy. The tool’s performance is impressive, with even 1” PEX expanding within a few seconds. This speed and efficiency are invaluable, especially when tackling larger projects or working in challenging conditions.

One area where the ProPEX Expander truly shines is in its ability to reduce physical strain. Traditional manual PEX expansion tools require significant effort and can be tiring to use, particularly during extended periods. The battery-powered ProPEX Expander eliminates this issue, allowing for effortless expansions with the simple pull of a trigger. This not only increases productivity but also minimizes the risk of injury, making it a safer option for both professionals and DIY enthusiasts.

Despite its high price point, the ProPEX Expander is a worthwhile investment for anyone serious about PEX plumbing. Its superior build quality, consistent performance, and user-friendly design make it a valuable addition to any toolkit. The tool’s ability to handle various pipe sizes with ease, coupled with its efficient operation, ensures that it will save time and effort on every project. While there are minor areas for improvement, such as the inclusion of a PACKOUT compatible case and a more durable instruction manual, these do not detract significantly from the tool’s overall value.

In conclusion, I highly recommend the Milwaukee ProPEX Expander for anyone involved in PEX plumbing installations. Its combination of durability, efficiency, and ease of use makes it an indispensable tool for both professionals and DIY enthusiasts. The investment is justified by the time and effort saved on each project, and the peace of mind that comes with secure, leak-free connections. Milwaukee has once again delivered a high-quality tool that lives up to its reputation, making the ProPEX Expander a valuable addition to any plumbing toolkit.
