I thought my coach had PEX as OEM plumbing, but now I'm not sure. It has plastic tubing with some sort of conical compression fitting that appears to be glued onto the tubing. As I'm doing some repairs/upgrades I'm curious as to:
* What is the original system called
* Is it compatible with PEX fittings

Black in the 1976 Royale, grey in the 1978 Palm beach, but it appears to be the same stuff.

The original plumbing was copper, then they switched to polybutylene, which is usually grey and as you described.
Sharkbite type fittings will work, but I don't have enough time/experience with them in an RV application to recommend push-on fittings. I did replace my kitchen faucet and use Watts plastic push-on fittings to hook up to the polybutylene original lines.

Richard--As everyone has told you, you have polybutylene piping. If you want to use pex in making repairs/mods, Watts makes a transition coupler (LFP-505) that will connect the two together. You should be able to find them at a good hardware store. Don't use regular pex fittings for the polybutylene!
Thanks,

If you need to make a connection in an inaccessible area you can Mc Gyver it by cutting the Quest line, using a brass barb fitting to the other line, heating the line until softened, pushing it on and tighten 2 hose clamps while still soft.
