94 Adventurer polybutylene.

Ok guys, I'm at my wits end. I've bought every kind of coupling I can find to change to pex, but can't find one to fit the poly. Any help?

I found some Snake Bite crimp adapters that go from PEX to PB at either Home Depot or Lowes.

Search for "pex pb 1/2" on Amazon for a wide variety.

Eagle Claw (Lowe's equivalent) work with PB without having to buy specific ones like the Shark Bite ones. I personally have used Sea Tech fittings which are available at most marine and rv centers and are specifically labeled as suitable for PB use. I found they are priced competitively to the big box stores and seem to have a wider variety more suited to the 3/8 size common in our rigs. Here's a shameless plug for the vendor I buy my stuff through Discount Marine and Boat Supplies - Inflatable Sales - Defender

Qest and Flair-It compression fittings work fine on polybutyl. I've used both, but like the Flair-It best because it is all hand-tighten stuff. Quick and easy. Flair-It will join poly to Pex too.
