Got a port I need to cap off on a hydraulic manifold, threading is G 1/4 - 19 BSPP. This plug gonna fit that up right?

That's what this one's made for. The SS9030-04 carries a G 1/4 - 19 male BSPP thread, so it'll seat right into a female BSPP port of that same size without any adapter in between. At 18.5mm long with a 19mm across-flat hex, you can torque it down with a standard wrench and get a solid seal on that open port.

got a port with G 1/4 - 19 threads, is this plug the right one or am i mixing up BSPP and something else
Answer by: Customer Support on Mar 31, 2026, 3:59 PM
The key is the thread callout. This plug is a male BSPP with G 1/4 - 19 threading, so it matches a female BSPP port with that same G 1/4 - 19 spec.
