The PARKER 12 F5OX-S is a steel flared tube straight thread connector designed for high-pressure hydraulic and fluid power lines. It features a 37-degree flare end mating to an SAE O-Ring Boss (ORB) port, providing a leak-resistant metal-to-face seal. The connector handles dynamic working pressures up to 5000 psi and temperatures up to 500 degrees F. It conforms to ISO 8434-2, SAE 070120, and SAE J514 standards. Licensed HVAC, plumbing, and hydraulic technicians install this type of fitting in industrial, mobile, and commercial fluid systems where tube-to-port connections must hold under sustained pressure and thermal cycling.
This fitting suits applications where a 3/4 inch OD flared tube must terminate at an SAE straight thread O-ring boss port. Typical scenarios include hydraulic power units, industrial machinery fluid circuits, and commercial refrigeration or HVAC equipment that uses SAE-standard flare connections. The UNF thread standard and 37-degree flare geometry make it a direct match for SAE J514-compliant port assemblies. The compact overall length of 1.97 inches allows installation in space-constrained equipment panels and manifold blocks.
Designed as an OEM-style replacement or service fitting for fluid power and hydraulic systems using 3/4 inch OD flared tubing and SAE straight thread O-ring boss ports conforming to SAE J514 and ISO 8434-2 specifications.
Installation should be performed by a qualified hydraulic or mechanical technician. De-pressurize and isolate the fluid circuit completely before removing or installing any fittings. Inspect the flare seat and O-ring sealing surface for nicks or contamination before assembly. Torque to the fitting manufacturer and system designer specifications; do not over-tighten, as this can damage the flare seat or O-ring groove.
