FAQ
What does this adapter connect?
It joins 3/4 in. insert poly pipe or hose (barb end) to a 3/4 in. female NPT threaded fitting.
Is it safe for drinking water?
Yes. It is lead-free bronze, intended for potable water systems where lead-free fittings are required.
Do I need thread sealant on the NPT end?
Yes. Apply Teflon tape or pipe dope to the male NPT thread; the insert barb end needs only a clamp.
How tight should the NPT thread be?
Hand-tighten, then turn 2 to 3 turns past hand tight. See our turns-past-hand-tight guide above.
