Parker 4 F65OL-S Swivel Connector 7/16-20 Orfs Sae-orb Steel

Product Description

The PARKER 4 F65OL-S is a compression tube straight thread swivel connector designed for high-pressure hydraulic and fluid system applications. It provides a leak-free transition between an O-Ring Face Seal (ORFS) tube end and an SAE straight thread O-ring boss (SAE-ORB) port. Constructed from steel, this fitting handles working pressures up to 9,200 psi, making it suitable for demanding industrial and mobile equipment environments. The swivel design allows the tube side to rotate during installation, reducing torsional stress on the tube and simplifying assembly in tight spaces. Licensed plumbers, hydraulic technicians, and fluid power specialists are the primary installers.

This connector is used wherever a 1/4-inch outside diameter compression tube must terminate at a straight thread SAE-ORB port. Typical applications include hydraulic power units, mobile equipment, industrial machinery, and high-pressure fluid transfer lines. The 7/16-20 UNF thread size corresponds to standard SAE-ORB port sizing commonly found on pumps, valves, manifolds, and cylinders. Its steel construction suits both stationary and mobile hydraulic systems operating across a wide range of pressures.

Key Features

• ORFS x SAE-ORB end connections provide a dual-seal, leak-resistant joint suitable for high-pressure service
• Maximum working pressure of 9,200 psi supports demanding hydraulic system requirements
• Swivel design on the tube end reduces torsional stress and simplifies installation in confined spaces
• 7/16-20 UNF straight thread conforms to SAE-ORB port standards
• Steel construction provides durability in hydraulic and fluid power environments
• Compatible with 1/4-inch outside diameter compression tube

Compatibility

Designed as an OEM-style replacement or direct-fit connector for hydraulic systems using 1/4-inch outside diameter compression tubing terminating at 7/16-20 UNF SAE straight thread O-ring boss ports.

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 fittings. Inspect the O-ring and sealing surfaces for damage before assembly, and replace the O-ring if any deformation or cuts are present. Follow the fitting manufacturer and system designer guidelines for proper assembly sequence; do not overtighten, as steel fittings at SAE-ORB ports rely on O-ring compression, not thread crush, for sealing.
