Parker 6 Jlo-s Tube Union Orfs Steel 1/2 Inch 9200 Psi

Product Description

The PARKER 6 JLO-S is a compression tube union with O-Ring Face Seal (ORFS) end connections, constructed from steel for use in high-pressure hydraulic and fluid system applications. This fitting creates a leak-resistant union between two tube ends using an O-ring sealing surface, which eliminates the metal-to-metal contact that conventional flare fittings rely on. It accepts a 1/2-inch outside diameter tube and is rated to a maximum working pressure of 9200 psi. Licensed technicians and fluid power specialists install this fitting in hydraulic lines, industrial equipment, and mobile machinery where reliable, vibration-resistant connections are required.

This union fitting is suited for both stationary and mobile hydraulic systems operating at elevated pressures. It is commonly used when connecting two tube segments in a straight-line run without the need for a threaded port. The ORFS design is preferred in applications where leak-free performance is critical, including agricultural equipment, construction machinery, and industrial fluid circuits. The steel construction provides durability in harsh service environments where corrosion and mechanical stress are common factors.

Key Features

• O-Ring Face Seal (ORFS) end connections provide a reliable, leak-resistant seal under high-pressure conditions
• Rated to 9200 psi maximum working pressure for demanding hydraulic applications
• Accepts 1/2-inch outside diameter tubing on both ends
• Steel construction for strength and durability in industrial and mobile equipment environments
• Union configuration allows straight in-line tube-to-tube connection without port threads

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 1/2-inch OD tubing with O-Ring Face Seal end connections.

Installation Notes

Installation should be performed by a qualified fluid power technician or hydraulic system specialist. Depressurize and isolate the hydraulic circuit fully before disassembling any fittings or tubing. Inspect the O-ring for damage before assembly and ensure the sealing face is clean and free of debris. Do not overtighten — follow the fitting manufacturer's recommended assembly procedure for ORFS connections to avoid deforming the sealing surface.
