PEX tubing is more flexible than rigid galvanized or copper pipe. Since it can bend, PEX requires fewer fittings. Still, particularly when adapting to other devices, some fittings must be made. Six primary options exist for making these connections: crimp, clamp, PEX press, expansion, compression, and push-fit. The first two options, crimp and clamp, use the same fittings. They call for relatively inexpensive tools and the associated rings. PEX press and expansion (i.e. Uponor ProPEX) are separate, unique systems which demand more costly tools. These methods are employed most commonly by those who work in the trade. Compression and push-fit fittings need no tools to connect to PEX tubing. While push-fit fittings are popular with do-it-yourselfers, they continue to become increasingly more accepted among professional installers. SharkBite and John Guest fittings are two examples.
To see the differences that exist among these fitting-styles, visit SupplyHouse’s YouTube account. Our new PEX fittings videos show the various methods in action. They will help new PEX users decide which option to use for themselves.
