Parker 8 HL6-S Swivel Union Orfs Steel 1/2 Inch 9200 Psi

Product Description

The PARKER 8 HL6-S is a compression tube swivel union with an O-Ring Face Seal (ORFS) end connection, built for high-pressure hydraulic and fluid system applications. Constructed from steel, this fitting connects two tube ends while allowing rotational movement to ease assembly and reduce stress on the line. The swivel design accommodates installation in tight or awkward routing scenarios without twisting the tubing itself. Rated to 9200 psi maximum working pressure, it is suited for demanding industrial, mobile equipment, and fluid power systems. Licensed trades and fluid power technicians install this fitting where a leak-free, vibration-tolerant connection is required.

This fitting is designed for use with 1/2 inch outside diameter tubing and uses UNF thread standard on the swivel end. ORFS connections provide a reliable metal-to-metal plus O-ring seal that resists leakage under pressure fluctuation and vibration. Typical applications include hydraulic plumbing on mobile machinery, industrial fluid power circuits, and any system where tube routing requires a union that can rotate during make-up. It is commonly installed by hydraulic technicians, pipefitters, and mechanical contractors working on high-pressure fluid systems.

Key Features

• O-Ring Face Seal (ORFS) end connections for positive leak-free sealing under high pressure
• Swivel union design allows rotation during assembly to reduce tube stress and simplify routing
• Steel construction for durability in high-pressure hydraulic environments
• Rated to 9200 psi maximum working pressure
• UNF thread standard for broad compatibility with standard hydraulic hardware
• Fits 1/2 inch outside diameter tubing

Compatibility

Designed as a standard ORFS swivel union fitting for use in hydraulic and fluid power systems requiring a 1/2 inch OD tube connection with UNF threading and O-Ring Face Seal end connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or pipefitter familiar with high-pressure fluid system assembly. Depressurize and isolate the hydraulic circuit fully before removing or installing any fitting. Inspect the O-ring sealing surface for nicks or contamination prior to assembly, and use the correct O-ring lubricant per system fluid compatibility. Torque the fitting according to the system designer or equipment OEM specifications; do not over-tighten, as this can damage the ORFS sealing face.
