Bspp Countersunk Sealed Plug

That's the kind of application this plug is built for. It's a male G 1-1/2 - 11 BSPP threaded fitting, so it'll thread directly into a female 1-1/2 inch BSPP port on a manifold. The countersunk profile keeps it sitting low once it's installed, which helps if clearance around that port face is tight. Steel construction, 55mm hex width for solid torque during installation.

For sealing off unused or inactive ports in a hydraulic circuit, this plug is meant for exactly that job. It is a steel, male BSPP plug sized for a 1-1/2 inch port with a G 1-1/2 - 11 thread, commonly used on manifolds, valves, cylinders, and similar hydraulic components.

The hex width on this BSPP countersunk plug is 55mm, so you'll need a wrench that size to tighten or remove it.
