Got a port that needs to be capped off on a hydraulic manifold, this plug rated for that kind of use, and will the 1/8 BSPT thread actually match up right?

Answer by: Customer Support on Jan 1, 2026, 6:03 AM

For standard 1/8" BSPT ported manifolds, yes, this should seat properly. The thread spec is R 1/8 - 28, which is the male BSPT designation, so as long as your manifold port is a matching female BSPT connection, you'll get a solid fit. Steel construction holds up well in hydraulic manifold applications, and the hex countersunk profile means you can torque it down without needing much clearance around the port.

trying to plug a port on a hydraulic manifold, is this the one with the 1/8 BSPT male thread?

Answer by: Customer Support on Mar 11, 2026, 7:09 AM

For a BSPT port that takes an R 1/8 - 28 male thread, this plug matches that size and thread callout. It is a steel hex countersunk plug meant to seal off that type of connection.
