Frequently Asked Questions

Q. "Are these fittings permanent?"
A. No. These fittings can be removed using the quick and easy to use "disconnect tool".

Q. "Why do some of the push connect fittings say FNPT and MNPT? I thought they were all push to connect?"
A. Some of the push connect fittings specify FNPT or MNPT because one side has either male or female pipe thread to make transition from threaded fittings or pipe easier.

Q. "Do you offer any other push connect fittings?"
A. Yes, we offer these quick (push to fit) fittings: John Guest quick connect fittings for copper, CPVC and PEX and SharkBite® fittings. We also offer quick connect fittings for garden hoses.
