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

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

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

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

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!

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

I bought as a back up for problems that just seem to happen

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