Parker 12-8 F5OX-S Steel Flare Connector 3/4 in Od Sae-orb

Product Description

The PARKER 12-8 F5OX-S is a steel flared tube straight thread connector designed to join 37-degree flared tubing to SAE straight thread O-ring boss (SAE-ORB) ports. It is used in hydraulic and fluid power lines where a reliable, leak-resistant connection between a flared tube end and a threaded port is required. The connector carries a maximum working pressure of 5000 psi and handles temperatures up to 500 degrees F, making it suitable for demanding industrial and mobile hydraulic applications. Installation is performed by hydraulic system technicians and pipefitters working on high-pressure fluid circuits.

This connector is suited for use in hydraulic systems, fluid power assemblies, and high-pressure plumbing circuits requiring a 37-degree flare-to-SAE-ORB transition. The 3/4 inch tube OD and 3/4 SAE-ORB thread sizing make it appropriate for mid-range flow lines in both stationary and mobile equipment. It meets ISO 8434-2, SAE 070120, and SAE J514 standards, confirming dimensional and performance compliance for use in OEM and aftermarket hydraulic assemblies.

Key Features

• 37-degree flare end mates to standard SAE J514 flared tube connections
• SAE-ORB straight thread end provides a positive O-ring seal at the port face
• Rated to 5000 psi maximum working pressure for high-pressure hydraulic service
• Maximum working temperature of 500 degrees F supports high-heat environments
• Steel construction for strength and durability in hydraulic fluid service
• Meets ISO 8434-2, SAE 070120, and SAE J514 standards

Compatibility

Designed for use with 3/4 inch OD tubing with a 37-degree flare end connecting to 3/4 SAE straight thread O-ring boss ports in hydraulic and fluid power systems conforming to SAE J514 and ISO 8434-2 standards.

Installation Notes

Installation is typically performed by qualified hydraulic technicians or pipefitters. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the O-ring and flare seat for damage before assembly, and ensure the flared tube end is properly formed to the 37-degree angle to achieve a leak-free joint. Follow applicable SAE and ISO torque and assembly guidelines for straight thread O-ring boss fittings.
