Parker 8 Klo-s Tube Union Orfs Steel 1/2 Inch 9200 Psi

Product Description

The PARKER 8 KLO-S is a compression tube union with an O-Ring Face Seal (ORFS) end connection, manufactured in steel. It joins two tube runs of the same outside diameter with a leak-resistant face seal design that uses a captive O-ring to eliminate weeping at the fitting interface. With a maximum working pressure of 9200 psi and a UNF thread standard, this union is built for high-pressure hydraulic and fluid power circuits. It is typically installed by hydraulic technicians, industrial maintenance mechanics, and fluid power specialists working on mobile or stationary hydraulic systems.

This fitting is suited for high-pressure hydraulic plumbing in industrial, mobile, and agricultural equipment applications. The ORFS design is commonly specified where vibration, pressure spikes, or field-service demands make a reliable, serviceable seal essential. The 1/2 inch tube outside diameter sizing places it in a common range for mid-capacity hydraulic circuits, including valve block plumbing, cylinder supply lines, and pump outlet connections.

Key Features

• O-Ring Face Seal (ORFS) end connections for leak-resistant, high-integrity tube joining
• Maximum working pressure of 9200 psi, suitable for demanding hydraulic circuits
• UNF thread standard for broad compatibility with standard hydraulic hardware
• Steel construction for durability in high-pressure and high-cycle service
• 1/2 inch tube outside diameter fits a widely used hydraulic tubing size

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems using 1/2 inch OD tubing with O-Ring Face Seal ORFS connections and UNF thread standard hardware.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and de-energize the hydraulic system completely before removing or installing any fitting. Inspect the O-ring for damage before assembly and replace it if any nicks or deformation are present. Torque fitting connections in accordance with the system designer's specifications and applicable hydraulic system standards.
