Parker 6-6 F6L-S Swivel Connector 3/8-18 Nptf Orfs Steel

Product Description

The PARKER 6-6 F6L-S is a compression tube pipe thread swivel connector designed to join an O-Ring Face Seal (ORFS) tube end to a National Pipe Thread Fuel (NPTF) port. Constructed from steel, this fitting provides a leak-resistant connection by combining the sealing reliability of an ORFS face seal with the thread engagement of an NPTF pipe thread. It is rated for a maximum working pressure of 9,200 psi, making it well suited for high-pressure hydraulic and fluid power circuits. The swivel design on the ORFS end allows for rotation during assembly to simplify alignment without twisting the connected tube or hose. Licensed plumbers, hydraulic technicians, and fluid power specialists install this type of fitting in industrial and mobile equipment applications.

This fitting is used in hydraulic systems, fluid power assemblies, and high-pressure tubing circuits where a transition between an ORFS tube connection and an NPTF threaded port is required. It is appropriate for both stationary industrial hydraulic equipment and mobile machinery. The 3/8-18 thread size fits standard 3/8-inch NPTF ports, and the 3/8-inch tube outside diameter matches standard 3/8-inch compression tube lines. Typical installation environments include hydraulic power units, cylinder circuits, and manifold port connections.

Key Features

• ORFS x NPTF end connections provide a reliable transition between face-seal tube fittings and pipe-thread ports
• Maximum working pressure of 9,200 psi supports high-pressure hydraulic circuit demands
• Swivel design on the ORFS end simplifies tube alignment during assembly
• Steel construction for durability in industrial and mobile hydraulic service
• 3/8-18 NPTF thread size for standard port compatibility
• 3/8-inch tube outside diameter matches standard compression tube lines

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a 3/8-inch ORFS tube connection to a 3/8-18 NPTF threaded port.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the ORFS sealing face and O-ring for damage before assembly, and ensure the NPTF threads are clean and free of debris. Thread sealant or tape is not required on NPTF threads when proper thread engagement is achieved, but follow the equipment manufacturer's instructions and applicable fluid power standards.
