Frequently asked questions
What thread size is this adapter?
It is a 1-inch female NPT (National Pipe Taper) thread, which seals against a matching 1-inch male NPT fitting when wrapped with thread-seal tape.
Is this a genuine BE Pressure part?
Yes. It is a factory BE Pressure component, so it matches the thread tolerances and pressure rating of BE pumps and washers.
Do I need thread tape to seal it?
NPT threads are tapered and typically need PTFE thread-seal tape or pipe dope to make a reliable, leak-free seal under pressure.
