Product Q&A
1 Question1 Question
Q: can this fitting be used to connect 3/4 Pro pex to a water pressure regulator using the expansion method of connecting to the Pro Pex pipe? Is any thing else needed? If not , what fitting do you recommend. Thank you

Verified Reply- PexSupply StaffThis fitting (part A4342575) is actually designed for connecting 3/4" copper to R25 threads. When connecting 3/4" PEX-A tubing to a 3/4" water pressure regulator, you will probably need a 3/4" male x ProPEX adapter (part LF4527575), a 3/4" female x ProPEX adapter (part LF4577575), or, if the adapter has sweat connections, a 3/4" ProPEX x copper fitting adapter (part LF4507575).
