05MORB HOLLOW HEX PLUG

Description & Features

Manufactured by Brennan Industries, this -5 ORB hollow hex plug is designed to close off unused or inactive O-ring boss ports in hydraulic circuits and manifolds. The hollow hex drive allows for installation using a standard hex key, making it well suited for confined spaces where a conventional wrench may not fit.

As a 05MORB Hollow Hex Plug, it threads into male O-ring boss ports and provides a reliable, leak-resistant seal through metal-to-body contact combined with the O-ring sealing method standard to ORB connections. This makes it a practical choice for blocking ports on hydraulic valves, cylinders, pumps, and related fluid power components.
