Parker 6 F65OL-S Swivel Connector 9/16-18 Orfs Sae-orb Steel

Product Description

The PARKER 6 F65OL-S is a compression tube straight thread swivel connector designed for high-pressure hydraulic and fluid power line assemblies. It transitions between an O-Ring Face Seal (ORFS) tube end and an SAE Straight Thread O-Ring Boss (SAE-ORB) port, providing a leak-resistant, vibration-tolerant connection. Constructed from steel, this fitting handles working pressures up to 9200 psi, making it suitable for demanding mobile hydraulic, industrial, and fluid power applications. The swivel design allows the tube to be positioned during installation without twisting the assembly. Licensed plumbers, hydraulic system technicians, and fluid power specialists are the primary installers.

This fitting is used in hydraulic systems, fluid power circuits, and high-pressure pneumatic lines where a straight-thread port connection meets a compression tube run. It accepts a 3/8-inch outside diameter tube on the ORFS end and threads into a 9/16-18 UNF SAE-ORB port. Typical installation scenarios include mobile equipment hydraulics, industrial machinery plumbing, and heavy-duty fluid handling systems requiring reliable, reusable connections. It is sold individually and available in single-unit quantities.

Key Features

• ORFS x SAE-ORB end connections for leak-resistant, high-pressure service
• Steel construction for strength in demanding hydraulic environments
• Rated to 9200 psi maximum working pressure
• Swivel design allows tube alignment without twisting the assembly during installation
• 9/16-18 UNF straight thread for precise port engagement
• Accepts 3/8-inch outside diameter compression tube

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 3/8-inch OD tube ORFS connection to a 9/16-18 UNF SAE-ORB threaded port.

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 sealing surfaces for nicks or contamination before assembly, and replace the O-ring if damaged. Tighten to the fitting manufacturer's recommended procedure for SAE-ORB straight-thread ports — back off and re-engage to seat correctly rather than relying on thread torque alone for sealing.
