10 PIECES XFITTING 1/2 PEX X 1/2 PB (POLYBUTYLENE) SPLICING COUPLING WITH RING, REPAIR KIT, BRASS

good but I needed two crimp rings (on the polybutylene side) to assure leak free.

If you’re modifying a polybutylene (Quest) water line system and want to switch to PEX, these will do the trick.

Works as it should. Was able to make my repair with no leaks.

Works perfectly. Saved me a lot of time and money. Great product. Will definitely buy again

Worked as designed to do.

These PB to PEX adapters work great for running new PEX lines in a house with polybutalyne pipes.

I was replacing polybutylene pipes underneath the house but there were a couple of lines that went they a maze throughout the house so I wanted to replace with PEX right up to the point where these went up into the house leaving the last few feet as polybutylene. This product worked great allowing me to connect my new PEX to the old polybutylene. Also, they kept these together with cable ties making it easy to keep the adapter connections together. They would have been easily lost had they not been cable tied together.

received in timely matter,product was just what i needed

These adaptors work great! Thanks
