Bspp Cap

A 1-inch BSPP female port is exactly what this cap is sized for. The G 1-11 thread callout confirms the fit, and since the cap itself has a female connection, it threads onto a male BSPP port to seal it off clean. Steel construction keeps it solid under normal hydraulic conditions. At 29mm long and 41mm across the wrench flats, it gives you enough to tighten it down properly without any fuss.

You want the thread callout to line up. This cap is a BSPP female with a G 1 - 11 thread in 1 inch size, so it is made to screw onto a matching G 1 - 11 male BSPP connection.
