PEX Connection

Yodane

Which connection method is more reliable?

Daniel Holzman

This topic has been discussed repeatedly on this forum, do a search for PEX connection to see dozens of threads. Some use expansion fittings (Wirsbo), some use crimp ring fittings, some use sharkbites, all have opinions.

If a pro plumber does it, all of the connections are reliable.

If a DIY person does it, then in my opinion, the Wirsbo/Uponor PEX connection system is the most reliable.

Reason is that connections in the Wirsbo/Uponor PEX system are made by expanding the end of the PEX tubing and a PEX ring. The fitting is inserted and the tubing and ring contract around the fitting. The PEX tubing and ring contract "evenly" around the entire circumference of the fitting. All connections will be the same every time. No "go/no-go" gauge is needed to verify that crimp rings were properly crimped.
