Parker 4 C6LO-S Swivel Elbow O-ring Face Seal 1/4 in Steel

Product Description

The PARKER 4 C6LO-S is a compression tube swivel elbow fitting with an O-Ring Face Seal (ORFS) end connection. It is manufactured from steel and rated for a maximum working pressure of 9200 psi. The swivel design allows the elbow to rotate during assembly, reducing tube stress and making it easier to align mating connections without twisting the hydraulic line. This fitting is installed by hydraulic technicians, fluid power mechanics, and industrial maintenance professionals working on high-pressure hydraulic circuits.

This fitting is suited for high-pressure hydraulic plumbing where a 90-degree directional change is required on a 1/4 inch outside diameter tube. ORFS end connections provide a leak-free metal-to-metal seal backed by a face-mounted O-ring, making this fitting a reliable choice for mobile equipment, industrial machinery, and hydraulic power units operating under demanding pressure conditions. The UNF thread standard ensures compatibility with standard hydraulic port connections across a wide range of equipment.

Key Features

• Swivel elbow design allows rotation during assembly to reduce tube and fitting stress
• O-Ring Face Seal (ORFS) end connection for leak-free performance at high pressure
• Maximum working pressure of 9200 psi for demanding hydraulic applications
• Steel construction for durability in industrial and mobile hydraulic environments
• UNF thread standard for broad port compatibility
• Fits 1/4 inch outside diameter compression tube

Compatibility

Designed as an OEM-style replacement or service fitting for high-pressure hydraulic systems using 1/4 inch outside diameter tubing with O-Ring Face Seal port connections and UNF threading.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and lock out the hydraulic system completely before removing or installing any fitting. Inspect the O-ring and sealing face for damage before assembly and replace the O-ring if any deformation or nicks are present. Tighten to the fitting manufacturer's specified torque range using appropriate hydraulic fitting wrenches — do not over-torque, as this can damage the ORFS sealing surface.
