Parker 4-6 F5OX-S Steel Flare to Sae-orb Connector 1/4 in

Product Description

The PARKER 4-6 F5OX-S is a steel flared tube straight thread connector designed to join 37-degree flared tube lines to SAE straight thread O-ring boss (ORB) ports. Built for high-pressure hydraulic and fluid power systems, this fitting handles dynamic working pressures up to 6000 psi and operating temperatures up to 500 degrees F. The 1/4 inch tube OD end accepts a standard 37-degree flare per SAE J514, while the male straight thread end seals against an O-ring boss port face. Licensed plumbers, pipefitters, and hydraulic system technicians install this type of connector in industrial, mobile, and OEM fluid power circuits.

This connector suits applications where a flared tube line must terminate at a manifold, valve, pump, or cylinder with an SAE-ORB straight thread port. Common install scenarios include hydraulic power units, mobile equipment, and machine tool circuits requiring leak-free connections at elevated pressure. The 1.29 inch overall length keeps the fitting compact in tight plumbing layouts. It is sold as a single piece and is appropriate wherever a Flare x SAE-ORB end configuration is specified.

Key Features

• 37-degree flare end conforms to SAE J514 and ISO 8434-2 standards
• SAE-ORB straight thread end provides a metal-to-O-ring face seal for reliable leak resistance
• Rated to 6000 psi dynamic working pressure for demanding hydraulic service
• Rated to 500 degrees F maximum working temperature
• Steel construction for strength and durability in industrial fluid power circuits
• Compact 1.29 inch overall length suits tight plumbing envelopes

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and fluid power systems requiring a 37-degree flare tube connection to a 9/16-18 UNF SAE straight thread O-ring boss port, per SAE J514 and ISO 8434-2.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed pipefitter. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the O-ring on the straight thread end and replace it if damaged before assembly. Torque to the fitting manufacturer specifications for the port size and material; do not over-tighten steel fittings into aluminum ports.
