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

Product Description

The PARKER 8 ELO-S is a steel compression tube union with an O-Ring Face Seal (ORFS) end connection. It joins two tube runs in a hydraulic or fluid system, providing a leak-resistant connection through a flat-face O-ring seal that mates against a machined seat. Rated to 9200 psi maximum working pressure, this union is suited for high-pressure hydraulic lines. Threads conform to UNF standard. The fitting accepts 1/2 inch outside diameter tubing on both ends. Installation is handled by hydraulic technicians, pipefitters, and fluid power specialists on mobile equipment, industrial machinery, and fluid transfer systems.

This union fitting is used in hydraulic fluid systems where a straight inline tube connection is required. The ORFS design minimizes leak paths compared to flare-style connections, making it appropriate for high-pressure applications in industrial and mobile hydraulic circuits. Typical install scenarios include connecting steel or stainless hydraulic tubing runs in equipment assemblies, manifold plumbing, and service line repairs where a union-style disconnect point is needed.

Key Features

• O-Ring Face Seal (ORFS) end connections resist leaks under high-pressure conditions
• Rated to 9200 psi maximum working pressure
• Accepts 1/2 inch outside diameter tubing on both ends
• UNF thread standard for compatibility with standard hydraulic hardware
• Steel construction for durability in industrial and mobile hydraulic environments

Compatibility

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

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and bleed down the hydraulic system completely before disconnecting or installing any fittings. Inspect the O-ring and seating face for damage before assembly, and replace the O-ring if any deformation or nicks are present. Tighten to the fitting manufacturer's recommended procedure using a calibrated torque wrench and a backup wrench on the mating component to prevent line twist.
