Parker KP17689 Steel 45 Degree Flare X Orb Elbow 5/16 Inch Od

Product Description

The PARKER KP17689 is a steel 45-degree flared tube elbow fitting designed for hydraulic and fluid power plumbing applications. It connects a 37-degree flared tube end to an O-ring boss (ORB) port, providing a reliable, leak-resistant joint at pressures up to 6000 psi. The fitting has a 5/16 inch tube outside diameter and a 1/2-20 thread size conforming to the ORB standard. Licensed plumbers, hydraulic system technicians, and fluid power mechanics install this type of fitting when routing tubing at a 45-degree angle to a ported component such as a valve, manifold, or pump body.

This fitting is suited for high-pressure hydraulic lines, fluid power circuits, and industrial plumbing where a directional change in steel tubing is needed at a ported connection point. The 37-degree flare angle is the SAE standard used across a wide range of hydraulic and refrigeration-adjacent plumbing assemblies. It is typically found in mobile equipment, industrial machinery, and plant utility systems where steel tubing replaces hose for durability and vibration resistance.

Key Features

• 45-degree elbow body routes tubing at a right-angle offset to save clearance in tight installations
• 37-degree SAE flare seat provides a metal-to-metal seal on the tube end
• O-ring boss (ORB) port end delivers a positive, leak-resistant connection at the mating component port
• Rated to 6000 psi maximum working pressure for high-pressure hydraulic service
• Steel construction provides strength and durability in demanding industrial environments
• Package quantity of 4 pieces per package supports bench-stocking and small assembly jobs

Compatibility

Designed as an OEM-style replacement or new-install fitting for hydraulic and fluid power systems using 5/16 inch OD steel tubing with a 37-degree flare and 1/2-20 ORB port connections.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed plumber familiar with high-pressure fluid systems. Depressurize and drain the hydraulic circuit fully before removing or installing fittings. Inspect the flare seat and ORB port for nicks or debris before assembly, and verify the O-ring is seated correctly in the boss port before torquing. Follow the equipment manufacturer and applicable industry standards for fitting assembly procedures on high-pressure lines.
