Ask A Question

Description & Features

Designed for use in Male SAE O-Ring Boss ports, the 03Morb Hollow Hex Plug provides a reliable sealing solution in hydraulic systems where a port needs to be closed off without sacrificing thread integrity. Conforming to SAE J514, it features a 3/8-24 thread and an external hex head for straightforward installation with standard tooling.

Constructed from straight steel, this plug incorporates an NBR O-ring seal, which provides effective resistance to petroleum-based hydraulic fluids across a broad range of operating conditions. With an overall length of 0.400 mm, it is suited to compact manifold and valve body applications where space is a consideration. The hollow hex configuration allows for consistent torque application during assembly.
