The PARKER 8 C6LO-S is a compression tube swivel elbow fitting with an O-Ring Face Seal (ORFS) end connection, constructed from steel. It is designed to route hydraulic or fluid lines through a 90-degree change in direction while maintaining a leak-resistant seal via an O-ring at the face of the fitting. The swivel design allows the nut to rotate independently, making it easier to tighten connections in confined spaces without twisting the tubing. Rated to a maximum working pressure of 9200 psi, this fitting is suited for high-pressure hydraulic systems. The thread standard is UNF, and it accepts tubing with an outside diameter of 1/2 inch.
This fitting is used in mobile hydraulic equipment, industrial machinery, and high-pressure fluid conveyance systems where a reliable, vibration-resistant elbow connection is required. The ORFS configuration is a common choice on hydraulic circuits where zero-leak performance is critical, such as in construction equipment, agricultural machinery, and manufacturing lines. It is typically installed by hydraulic system technicians and millwrights working on tube and hose assemblies.
Designed as an OEM-style replacement or service fitting for high-pressure hydraulic tube assemblies using 1/2 inch OD tubing with ORFS connections and UNF threads.
Installation should be performed by a qualified hydraulic technician. Depressurize and bleed the hydraulic system completely before removing or installing any fittings. Inspect the O-ring for damage before assembly and ensure the mating face is clean and free of debris to achieve a proper seal. Torque the swivel nut to the fitting manufacturer's specification using appropriate hydraulic fitting tools.
