does this hook up to standard NPTF fittings or do i need some kind of adapter for the female end
Answer by: Customer Support on Mar 6, 2026, 10:13 AM
The female end on this coupling is 3/8 NPTF, so it threads directly onto standard 3/8 NPTF ports without any adapter needed. The male end uses UN thread to connect, and the whole thing operates on a thread-to-connect style, meaning no tools required to make or break the connection. It's a two-way valve setup, which keeps fluid from spilling out both sides when you disconnect.
