FAQ
What does an insert coupling do?
It joins two pieces of insert poly pipe or hose end to end. Each side slips inside the pipe and is secured with a clamp.
Is it safe for drinking water?
Yes. It is lead-free bronze, intended for potable water systems where lead-free fittings are required.
Is this threaded?
No. Both ends are insert hose barbs, so no thread sealant is needed—just slide on the pipe and clamp.
What is the pressure rating?
Rated to 150 psi. Stay within the lower of the fitting, pipe, and clamp ratings for your system.
