Steel Adapter, 1-14 Male O-Ring Face Seal Cap

For a 1-14 male O-Ring Face Seal fitting, yes, that's exactly what this cap is built around. It's a female ORS cap, so it threads onto the male end and seals the port. The cap is steel construction from the Danfoss/Eaton Aeroquip FF9863 series, so it's a known-quantity part for capping off hydraulic lines during storage, shipping, or when a port is temporarily out of service.

This steel adapter cap fits a 1-14 male O-ring face seal.

Capping off an open O-ring face seal port is exactly what this piece is built for. The 1-14 thread size with the male ORS configuration lets it seat against the flat face of a female ORS port and seal it off clean. If you've got an unused port on a manifold or valve block with that thread spec, this is the standard way to close it out without plugging the whole assembly.
