Question by: Jerry T on Oct 31, 2025, 8:22 AM
got a half inch male NPT port on my compressor manifold, will this coupler thread right on without needing any adapters?
Answer by: Customer Support on Nov 2, 2025, 7:27 AM
A 1/2 inch male NPT port is exactly what this coupler is built for. The thread on the coupler is 1/2 male NPT, so it screws directly into a female NPT port on your manifold. No adapters needed for that connection.
