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

good

Good value

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!

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

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.

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

Worked as designed to do.

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

The adaptors worked perfectly and the price was very competitive

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