Pex Transition Coupling - Products
A PEX transition coupling connects PEX to a different pipe type or PEX connection system, letting you tie new PEX into existing plumbing or join two methods. Moonshine Bath stocks PEX transition couplings for common material and system crossovers.

Frequently Asked Questions
What does a transition coupling connect?
It joins PEX to another piping material or connection method, for instance tying PEX into an existing copper or CPVC run, or between crimp and expansion systems. Check the listing for the exact transition.
Why not just use a regular coupling?
A standard coupling joins the same pipe type and size. A transition coupling is purpose-built to bridge two different materials or systems reliably and to code.
