Parker 6 Elo-s Steel Tube Union Orfs 3/8 in Od 9200 Psi

Product Description

The PARKER 6 ELO-S is a steel compression tube union with O-Ring Face Seal (ORFS) end connections, designed for high-pressure hydraulic and fluid system applications. It joins two tube lines of equal outside diameter using a leak-resistant ORFS interface that relies on a flat face seal against an O-ring rather than a flared or tapered seat. Rated to 9200 psi maximum working pressure, this union is suited for demanding hydraulic circuits where reliable, vibration-resistant connections are required. The UNF thread standard ensures broad compatibility with standard hydraulic fittings. Installation is performed by licensed hydraulic technicians and fluid power specialists.

This fitting is used in mobile hydraulics, industrial machinery, and fluid power systems where tube connections must maintain integrity under high pressure and dynamic loads. The ORFS design is common in applications where leak-free performance is critical, including agricultural equipment, construction machinery, and industrial hydraulic circuits. It connects two tube runs of 3/8 inch outside diameter in a straight union configuration without redirecting flow.

Key Features

• ORFS end connections provide a flat-face O-ring seal for leak-free performance at high pressure
• Rated to 9200 psi maximum working pressure for demanding hydraulic applications
• Steel construction for strength and durability in industrial and mobile equipment environments
• UNF thread standard for compatibility with standard hydraulic fittings and components
• Straight union body joins two 3/8 inch OD tube lines in a single inline assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/8 inch outside diameter tubing with O-Ring Face Seal connections and UNF thread standards.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit fully before disassembly or fitting installation. Inspect the O-ring seating surface for nicks or contamination before assembly, and use the correct O-ring lubricant per system fluid compatibility. Tighten to the fitting manufacturer's torque specification for the connection size using a calibrated torque wrench.
