Midland Industries FS680488 Run Tee Steel Hydraulic Orfs Adapter

Product Description

The MIDLAND INDUSTRIES FS680488 is a steel hydraulic run tee adapter designed for high-pressure fluid power systems. It features three connection ports: a 1/2-inch Male O-Ring Face Seal (ORFS) on port one with a 13/16-16 thread, a 1/2-inch Male Adjustable O-Ring Boss (ORB) on port two with a 3/4-16 thread, and a 3/4-inch Male ORFS on port three with a 13/16-16 thread. The run configuration allows inline flow to continue while branching off to a side port, making it a practical fitting for hydraulic circuit routing. Overall dimensions are approximately 2.8 inches in length and 1.6 inches in width. This fitting is installed by hydraulic system technicians and fluid power mechanics working on mobile or industrial equipment.

The FS680488 is used in hydraulic plumbing applications where a tee connection is needed between ORFS and adjustable O-Ring Boss ports. It is suited for steel hydraulic tubing and hose assemblies in mobile equipment, industrial machinery, and agricultural systems. The mixed-port configuration makes it useful when transitioning between ORFS and ORB fittings within the same circuit without additional adapters. It falls within the Steel O-Ring Face Seal Adapters product family and is intended for professional hydraulic system assembly and repair work.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect O-ring seals on all ports prior to assembly and replace if damaged or missing. Torque all connections to system and fitting manufacturer specifications using appropriate hydraulic fitting tools; do not use pipe wrench-style tools that can damage sealing surfaces.
