Parker PT-00203 Steel Flared Tube 90 Elbow 3/8 in Od

Product Description

The PARKER PT-00203 is a 90-degree flared tube elbow fitting machined from steel for use in high-pressure hydraulic and fluid power systems. It connects a 37-degree flared tube end to an O-ring boss (ORB) port, changing line direction by 90 degrees without requiring additional adapters. The fitting accepts a 3/8-inch tube OD on the flare end and a 7/8-14 thread on the ORB end. It is rated to 6000 psi working pressure and handles temperatures up to 500 degrees F, making it suitable for demanding industrial and mobile hydraulic applications. Licensed plumbers, hydraulic technicians, and industrial maintenance mechanics typically install this fitting.

This elbow is commonly used in hydraulic systems, lubrication circuits, and fluid power plumbing where a 90-degree direction change is needed between a flared tube line and an ORB-ported component such as a pump, valve, or manifold. It is appropriate for both stationary industrial equipment and mobile machinery requiring a compact, leak-resistant flare-to-ORB transition. The 37-degree flare angle conforms to SAE J514 standards, making it a standard choice for OEM and field service installations.

Key Features

• 90-degree elbow routes tubing at a right angle with a single fitting
• 37-degree flare angle meets SAE J514 and ISO 8434-2 specifications
• Flare x ORB end configuration connects flared tube lines to O-ring boss ports
• 6000 psi maximum working pressure for high-pressure hydraulic service
• Rated to 500 degrees F maximum working temperature
• Steel construction for durability in industrial and mobile hydraulic environments

Compatibility

Designed for use with 3/8-inch OD 37-degree flared tube lines connecting to 7/8-14 ORB-ported hydraulic components. Conforms to ISO 8434-2 and SAE J514 standards for broad compatibility with compliant hydraulic systems and equipment.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed mechanic. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Inspect the flare seat and O-ring boss port for damage or debris before assembly. Do not overtighten; follow the torque guidelines specified by the connected component manufacturer and applicable SAE standards.
