Parker 4 S5OLO-S Male Branch Tee 1/4 in Od Orfs Sae-orb

Product Description

The PARKER 4 S5OLO-S is a compression tube male branch tee fitting designed for high-pressure hydraulic and fluid-power plumbing applications. Constructed from zinc-plated steel, it provides corrosion resistance in demanding service environments. The fitting connects O-Ring Face Seal (ORFS) and SAE O-Ring Boss (SAE-ORB) end connections with a 7/16-20 UNF thread, accommodating 1/4 inch outside diameter tubing. Rated to 6000 psi maximum working pressure, this fitting is suited for hydraulic lines, mobile equipment, and industrial fluid systems where a branch connection is required. Installation is performed by licensed mechanics, hydraulic technicians, and journeyman pipefitters working on pressurized fluid circuits.

This male branch tee is used in applications requiring a branch takeoff from a main hydraulic or fluid-power line. Typical install scenarios include mobile hydraulic equipment, industrial machinery, and heavy-duty fluid transfer systems operating at elevated pressures. The ORFS x SAE-ORB end connection configuration makes it a common choice when transitioning between O-ring face seal tubing runs and SAE-ORB ported components such as valves, manifolds, and cylinders. The zinc-plated steel construction suits both indoor and moderate outdoor service conditions.

Key Features

• Zinc-plated steel construction for corrosion resistance in hydraulic service environments
• Rated to 6000 psi maximum working pressure for high-pressure fluid-power circuits
• ORFS x SAE-ORB end connections for cross-standard branch plumbing
• 7/16-20 UNF thread size for precise, leak-resistant seating with O-ring face seal
• 1/4 inch tube outside diameter compatibility for common small-bore hydraulic tubing
• Male branch tee configuration allows a single-outlet branch from a main fluid line

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid-power systems using 1/4 inch OD tubing with ORFS and SAE-ORB connections rated up to 6000 psi.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid-power systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring sealing surfaces for nicks or contamination before assembly, and use only clean, compatible hydraulic fluid or assembly lubricant on the O-rings. Follow applicable fluid-power piping standards and equipment manufacturer torque guidelines for ORFS and SAE-ORB connections.
