Parker 16 S5OLO-S Male Branch Tee 1 in Od Orfs Sae-orb 5500 Psi

Product Description

The PARKER 16 S5OLO-S is a compression tube male branch tee designed for high-pressure hydraulic and fluid power plumbing applications. It connects a 1-inch outside diameter compression tube to a branch port using an O-Ring Face Seal (ORFS) end and an SAE straight thread O-ring boss (SAE-ORB) male thread. The fitting is rated to 5500 psi maximum working pressure, making it suitable for demanding mobile hydraulic and industrial circuits. Constructed from zinc-plated steel for corrosion resistance, it carries a 1-5/16-12 UNF thread size. Installation is typically performed by hydraulic system technicians and industrial plumbers.

This fitting is used in hydraulic systems requiring a branch connection off a main tube run. The ORFS end provides a leak-free metal-to-metal face seal with an O-ring, while the SAE-ORB port threads into boss fittings on pumps, valves, cylinders, and manifolds. Typical applications include mobile equipment, agricultural machinery, construction equipment hydraulics, and industrial fluid power circuits where reliable branch connections under high pressure are required.

Key Features

• Rated to 5500 psi maximum working pressure for demanding hydraulic service
• ORFS x SAE-ORB end connections for leak-free sealing at both the tube and port ends
• 1-5/16-12 UNF thread with O-Ring Face Seal design minimizes the risk of vibration-induced leaks
• Zinc-plated steel construction provides corrosion resistance in harsh operating environments
• Male branch tee configuration allows a branch takeoff from the main tube line without additional adapters

Compatibility

Designed as a direct-fit male branch tee for hydraulic and fluid power systems using 1-inch OD compression tube lines with ORFS connections and SAE-ORB port bosses. Confirm tube OD, thread standard, and port type before installation.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial plumber familiar with high-pressure fluid systems. Depressurize and drain the hydraulic circuit completely before disassembly or fitting installation. Inspect and lubricate O-rings before assembly; do not overtighten, as ORFS fittings rely on O-ring compression rather than thread torque alone for sealing. Verify all connections are rated for the system operating pressure before returning the circuit to service.
