PERMCO 1/4 ORB HOLLOW HEX PLUG

Description & Features

Designed for use in hydraulic circuits, the Permco 1/4 ORB Hollow Hex Plug provides a reliable port-sealing solution compatible with 1/4-inch O-Ring Boss (ORB) threaded ports. The hollow hex drive allows for installation and removal using a standard hex key, making it a practical choice for accessible or recessed port locations.

Manufactured by Permco, this plug is suited for sealing unused ports on hydraulic pumps, motors, valves, and manifolds where a clean, leak-resistant closure is required. The ORB thread form provides a positive metal-to-face seal via the O-ring, reducing the risk of leakage under pressure compared to tapered thread alternatives.

What's this plug actually for?

It's a hollow hex plug designed to seal off a 1/4 ORB port in hydraulic systems. You'd use it to block a port you're not currently using.
