Parker 12 S5OLO-S Male Branch Tee Orfs Sae-orb 6000 Psi

Product Description

The PARKER 12 S5OLO-S is a male branch tee fitting designed for high-pressure hydraulic tube and port connections. It combines an O-Ring Face Seal (ORFS) tube end with an SAE O-Ring Boss (SAE-ORB) port connection, creating a branch tee configuration that routes flow to two outlets from a single port. The fitting is manufactured from zinc-plated steel for corrosion resistance and is rated to 6000 psi maximum working pressure. It accepts 3/4-inch outside diameter tubing and uses a 1-1/16-12 UNF thread standard. Hydraulic system technicians and fluid power specialists install this fitting in mobile equipment, industrial machinery, and fluid power circuits where a reliable, leak-resistant branch connection is required.

This fitting is suited for use in hydraulic systems operating at up to 6000 psi where branching a line off an SAE-ORB port is required. The ORFS face seal end provides a metal-to-metal seating surface supplemented by an O-ring, making it a preferred choice in high-pressure or vibration-prone environments where threaded NPT connections may be inadequate. Typical applications include construction equipment hydraulics, agricultural machinery, industrial power units, and other systems where clean, high-integrity tube branch connections are essential.

Key Features

• Male branch tee configuration routes hydraulic flow from a single SAE-ORB port to two ORFS tube connections
• Rated to 6000 psi maximum working pressure for demanding hydraulic circuits
• ORFS end connection delivers a reliable O-ring face seal for leak-resistant performance in high-vibration environments
• 1-1/16-12 UNF thread size compatible with standard SAE-ORB port specifications
• Accepts 3/4-inch outside diameter tubing
• Zinc-plated steel construction provides corrosion resistance for industrial and mobile equipment environments

Compatibility

Designed as a direct-fit replacement or new-installation fitting for hydraulic systems using ORFS tube connections mated to SAE O-Ring Boss ports with a 1-1/16-12 UNF thread and 3/4-inch outside diameter tubing.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect the O-ring seating surface and O-ring condition prior to assembly; a damaged or missing O-ring will result in leakage under pressure. Torque the fitting to the appropriate SAE standard value for the thread size referenced in the equipment service documentation, and verify system integrity by pressure-testing before returning equipment to service.
