Parker 12 Elo-s Tube Union Orfs Steel 3/4 in 6000 Psi

Product Description

The PARKER 12 ELO-S is a compression tube union with an O-Ring Face Seal (ORFS) end connection, constructed from steel for durability in high-pressure hydraulic and fluid system applications. This fitting joins two tube ends using UNF threading and an ORFS sealing interface, which creates a leak-resistant metal-to-metal plus elastomer seal at the face of the fitting. With a maximum working pressure rating of 6000 psi and a 3/4-inch tube outside diameter, this union is built for demanding industrial and mobile hydraulic lines where joint integrity is critical. Licensed plumbers, hydraulic system technicians, and fluid power specialists are the primary installers.

This fitting is suited for use in hydraulic power units, mobile equipment, industrial machinery, and fluid transfer systems where steel construction and ORFS sealing are specified. ORFS connections are widely used in applications requiring vibration resistance and leak-free performance under high-pressure cycling. The 3/4-inch OD sizing accommodates common mid-range hydraulic tubing found in both stationary and mobile equipment installations.

Key Features

• O-Ring Face Seal (ORFS) end connections for leak-resistant high-pressure joints
• Maximum working pressure of 6000 psi for demanding hydraulic service
• 3/4-inch tube outside diameter compatibility
• UNF thread standard for consistent engagement with standard hydraulic hardware
• Steel construction for strength and durability in industrial environments
• Union configuration allows in-line tube-to-tube connection without system modification

Compatibility

Designed as an OEM-style compression tube union for hydraulic and fluid power systems specifying 3/4-inch OD tubing with ORFS end connections and UNF threading at up to 6000 psi working pressure.

Installation Notes

This fitting is typically installed by hydraulic system technicians or licensed fluid power specialists. Depressurize and lock out the hydraulic system completely before removing or installing any fitting. Inspect and lubricate the O-ring before assembly to ensure proper sealing at the face. Follow the equipment manufacturer and applicable industry standards for assembly torque and tube preparation procedures.
