Parker 6 F5OX-S Flared Tube Straight Thread Connector

Product Description

The PARKER 6 F5OX-S is a steel flared tube straight thread connector designed to join 37-degree flared tubing to SAE straight thread O-ring boss (ORB) ports in hydraulic and fluid power systems. It features a 3/8 inch tube OD on the flare end and a 9/16 inch UNF straight thread on the ORB end. Rated to 6000 psi maximum working pressure and capable of handling temperatures up to 500 degrees F, this fitting is built for demanding industrial and mobile hydraulic applications. Licensed plumbers, hydraulic technicians, and fluid power specialists install this type of connector as a reliable leak-free interface between tubing runs and component ports.

This connector is suited for hydraulic circuits, fuel systems, and fluid transfer lines where a 37-degree flare tube must terminate at an SAE-ORB threaded port. It is appropriate for use in both industrial machinery and mobile equipment environments requiring rated high-pressure performance. The fitting conforms to ISO 8434-2, SAE 070120, and SAE J514 standards, making it suitable for OEM builds and MRO replacement installations where specification compliance is required.

Key Features

• 37-degree flare angle per SAE J514 for leak-free tube connections
• SAE straight thread O-ring boss (ORB) end ensures positive port sealing
• Rated to 6000 psi maximum dynamic working pressure
• Temperature range up to 500 degrees F (260 degrees C)
• Steel construction for durability in high-pressure hydraulic service
• Compliant with ISO 8434-2, SAE 070120, and SAE J514 standards

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems using 3/8 inch OD flared tubing and SAE straight thread O-ring boss ports conforming to SAE J514 and ISO 8434-2.

Installation Notes

This fitting is installed by licensed hydraulic technicians or fluid power specialists. Always depressurize and bleed down the hydraulic circuit 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 design specifications and verify for leaks before returning the system to service.
