Midland Industries FS6400O46 Straight Adapter Orfs X Orb

Product Description

The MIDLAND INDUSTRIES FS6400O46 is a straight hydraulic adapter that converts a 1/4-inch Male O-Ring Face Seal (ORFS) connection to a 3/8-inch Male O-Ring Boss (ORB) connection. Machined from steel, it is rated for a maximum operating pressure of 6000 psi and a maximum operating temperature of 375 degrees F. The adapter uses a 9/16-18 thread and is part of the FS6400 Series of ORFS-to-ORB fittings. It is installed in hydraulic plumbing lines where a face seal port must interface with a boss-style port, a common requirement in mobile equipment, industrial machinery, and fluid power systems.

This adapter is suited for hydraulic applications requiring a leak-resistant transition between ORFS and ORB port styles. The steel construction handles high-pressure hydraulic fluid service. Typical installation scenarios include connecting hydraulic hose assemblies, manifold ports, and valve bodies in both mobile and stationary hydraulic systems. It fits within the Hydraulics category under Steel O-Ring Face Seal Adapters. Licensed hydraulic technicians and fluid power mechanics are the primary installers.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic system completely before removing or installing any fittings. Inspect O-ring sealing surfaces for nicks or contamination prior to assembly, as surface damage can cause leaks under pressure. Follow applicable industry standards for hydraulic fitting assembly and torque procedures.
