Parker 8-8 F6L-S Swivel Connector 1/2-14 Nptf Orfs Steel

Product Description

The PARKER 8-8 F6L-S is a compression tube pipe thread swivel connector designed for high-pressure hydraulic and fluid power lines. It joins an O-Ring Face Seal (ORFS) tube end to a National Pipe Thread Fuel (NPTF) port with a swivel connection that allows rotational alignment during installation. Constructed from steel, the connector is rated for a maximum working pressure of 9,200 psi. The 1/2-14 thread size fits standard half-inch NPTF ports. This fitting is installed by licensed hydraulic technicians, millwrights, and industrial plumbers working on fluid power assemblies, mobile equipment, and high-pressure process lines.

This swivel connector is suited for both stationary and mobile hydraulic systems where tube-to-port connections must resist vibration, resist leakage under high pressure, and allow final angular adjustment at assembly. The ORFS end provides a metal-to-metal seal backed by an O-ring, minimizing leak paths in high-cycle or high-vibration applications. The NPTF male thread end seals on the thread form itself without relying solely on sealant tape. Typical applications include hydraulic power units, construction equipment, agricultural machinery, and industrial press lines.

Key Features

• Maximum working pressure of 9,200 psi for demanding hydraulic service
• ORFS x NPTF end connections combining O-ring face seal integrity with pipe thread engagement
• Swivel design allows rotational positioning to ease tube routing and reduce assembly stress
• 1/2-14 NPTF thread size fits standard half-inch pipe thread ports
• Steel construction provides strength and durability in high-pressure environments
• 1/2-inch tube outside diameter compression end for secure tube retention

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 1/2-inch ORFS tube connections mating to 1/2-14 NPTF threaded ports.

Installation Notes

Installation should be performed by a qualified hydraulic technician or industrial plumber familiar with high-pressure fitting assemblies. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the ORFS O-ring seat and the NPTF port threads for damage or contamination before assembly. Apply appropriate thread sealant to the NPTF end per system requirements, and torque to the fitting manufacturer's published specifications for this series.
