Parker 4 F5OX-S Flared Tube Connector 1/4 in Od Sae-orb

Product Description

The PARKER 4 F5OX-S is a steel flared tube straight thread connector designed to join 1/4 inch OD hydraulic or fluid tubing to SAE O-Ring Boss (ORB) ports using a 37-degree flare seat. The fitting features a Flare x SAE-ORB end configuration and is machined to UNF thread standards, making it a standard component in hydraulic lines, fluid power systems, and high-pressure tubing assemblies. It carries a maximum working pressure of 7500 psi and a maximum working temperature of 500 degrees F, supporting demanding industrial and mobile equipment applications. Licensed plumbers, hydraulic technicians, and fluid power specialists install this fitting as part of pressurized line assemblies.

This connector is suited for use in hydraulic systems, fluid power circuits, and industrial tubing runs where a 37-degree flare tube end must terminate at an SAE-ORB threaded port. The 1/4 inch tube OD and UNF thread form are common in compact hydraulic manifolds, mobile equipment hydraulics, and machine tool plumbing. Its all-steel construction supports continuous operation at elevated temperatures and pressures. This fitting is sold individually and requires no special tooling beyond standard flaring and wrenching equipment appropriate to the line size.

Key Features

• 37-degree flare seat conforms to SAE J514 and ISO 8434-2 standards for reliable leak-free sealing
• SAE O-Ring Boss (ORB) straight thread end provides positive port sealing with an O-ring face seal at the port
• Maximum working pressure of 7500 psi suitable for high-pressure hydraulic circuits
• Rated to 500 degrees F maximum working temperature for high-heat industrial environments
• All-steel construction for durability in demanding fluid power and hydraulic applications
• Overall length of 1.23 inches for compact installation in tight plumbing runs

Compatibility

Designed as an OEM-style straight thread connector for hydraulic and fluid power systems using 1/4 inch OD tubing with a 37-degree flare and SAE O-Ring Boss port connections per SAE J514, SAE 070120, and ISO 8434-2.

Installation Notes

Installation is performed by qualified hydraulic technicians or licensed fluid power specialists. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Use calibrated wrenching to avoid overtorquing the straight thread into the ORB port, as thread damage will compromise sealing. Verify the O-ring is properly seated in the port boss before torquing, and inspect the 37-degree flare seat on the tubing for damage or burrs before making up the connection.
