Parker 4 S6LO-S Swivel Branch Fitting Orfs Steel 1/4 in

Product Description

The PARKER 4 S6LO-S is a compression tube swivel branch fitting with an O-Ring Face Seal (ORFS) end connection, constructed from steel. This fitting is designed to create a leak-resistant branch connection in hydraulic tubing systems by using a face-seal o-ring to eliminate the potential for port leakage under high-pressure conditions. Rated to 9200 psi maximum working pressure, it is suited for demanding hydraulic circuits where reliable sealing is critical. The swivel design allows for rotational adjustment during installation, reducing the need to twist or stress the connected tubing. It is typically installed by hydraulic technicians and fluid power specialists working on industrial or mobile hydraulic equipment.

This fitting is used in hydraulic plumbing applications where a branch connection is required off a main tube run. The 1/4 inch outside diameter tube size and ORFS interface make it appropriate for compact, high-pressure hydraulic circuits found in mobile machinery, industrial equipment, and fluid power systems. It is a direct assembly component installed at the point of tube branching, where maintaining pressure integrity and minimizing potential leak paths are the primary concerns.

Key Features

• O-Ring Face Seal (ORFS) end connection provides a positive, leak-resistant seal at the port face
• Swivel design allows angular positioning during assembly without stressing connected tubing
• Rated to 9200 psi maximum working pressure for high-pressure hydraulic service
• Steel construction for strength and durability in hydraulic system environments
• 1/4 inch tube outside diameter sizing for compact hydraulic circuit applications

Compatibility

Designed as an OEM-style hydraulic fitting for use in high-pressure tube systems with ORFS port connections and 1/4 inch outside diameter tubing.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system fully before removing or installing any fittings. Inspect the o-ring sealing face for nicks or contamination before assembly, and verify the o-ring is properly seated before torquing the fitting. Follow the fitting manufacturer and equipment OEM torque specifications applicable to the fitting size and thread type in use.
