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.

Coupling did its job no leaks.

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

Converts the grey piping to Pex. A must have when there are some of the polybutylene piping that is in an impossible position to reach.

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

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!

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

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

received in timely matter,product was just what i needed

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