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

Great adapter for pex to polybutylene or braided nylon hose with a 1/2 inside diameter.

Heads Up! I bought these for my DIY faucet repair. They are for Poly to Pex fitment and the ends of brass insert are specific to type of pipe being used. One end has more grooves than the other end. I got 9 that were correct. But one was for Pex to Pex! If I had not noticed the difference? BIG Problem!

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

Worked as designed to do.

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.

Worked perfect for adding new plumbing on a 1990 manufactured home with polybutylene. Great quality and fit perfect.

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

These adaptors work great! Thanks

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

Product works as intended. No issues, good price. Very pleased.
