Parker 6 S5OLO-S Male Branch Tee 9/16-18 Orfs Sae-orb

Product Description

The PARKER 6 S5OLO-S is a compression tube male branch tee fitting designed for high-pressure hydraulic and fluid power lines. It connects a 3/8-inch outside diameter tube to a male branch port using an O-Ring Face Seal (ORFS) end connection mated with an SAE O-Ring Boss (SAE-ORB) port. The fitting is manufactured from zinc-plated steel for corrosion resistance and carries a maximum working pressure rating of 6000 psi. It is sized with a 9/16-18 UNF thread and is sold individually. Hydraulic technicians and fluid power mechanics install this type of fitting in mobile equipment, industrial machinery, and HVAC chiller systems where leak-free, high-pressure branch connections are required.

This male branch tee is suited for applications where a single hydraulic or fluid line must split into a branch circuit without introducing additional fittings or adapters. The ORFS interface provides a metal-to-metal face seal backed by an O-ring, which virtually eliminates leak paths at elevated pressures. The SAE-ORB male branch port threads directly into a boss port on manifolds, valve bodies, pumps, or cylinders. Typical installations are found in mobile hydraulics, off-highway equipment, industrial presses, and refrigeration systems using high-pressure refrigerant lines.

Key Features

• Maximum working pressure rated to 6000 psi for demanding hydraulic service
• ORFS x SAE-ORB end connections provide leak-resistant face-seal performance
• Zinc-plated steel construction resists corrosion in field and industrial environments
• 9/16-18 UNF thread size for standard hydraulic component compatibility
• Accepts 3/8-inch outside diameter tubing on the compression end
• Single-piece package simplifies procurement for service and repair jobs

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems using 3/8-inch OD tube with ORFS connections and SAE-ORB boss ports operating at pressures up to 6000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic familiar with ORFS and SAE-ORB fitting assembly procedures. Depressurize and isolate the hydraulic circuit fully before removing any existing fittings. Inspect the O-ring seating surface and boss port for nicks or contamination before assembly. Do not overtighten; follow the fitting manufacturer's standard assembly torque guidance for the thread size and material to avoid distorting the face seal or boss seat.
