Compared to rigid pipe, flexible PEX pipe has a lot of benefits in areas such as durability, reliability and cost-effectiveness. But when it comes to system installations, what connection method is best?
The five most common connection methods for PEX piping systems are crimp, clamp, push-to-connect, expansion, and expansion with compression. Here’s a more detailed look at each connection style and their benefits and challenges.
