Parker KP17823 Steel Flared Tube Connector 5/16 in 37 Deg

Product Description

The PARKER KP17823 is a steel flared tube connector designed for hydraulic and fluid-system plumbing applications where a reliable, leak-resistant connection is required. It features a 37-degree flare on the tube end and an O-ring Boss (ORB) port connection on the opposite end. The fitting accepts 5/16-inch tube OD and uses a 1/2-20 thread size. Rated for a maximum dynamic working pressure of 6000 psi, this connector is built for demanding service environments. Hydraulic technicians, fluid-power mechanics, and industrial plumbers rely on this type of fitting when connecting steel tubing to ported components such as valves, pumps, and manifolds.

The KP17823 is suited for use in hydraulic circuits, mobile equipment, industrial machinery, and high-pressure fluid-transfer systems. The flare-to-ORB configuration is a common interface found where hard tubing terminates at a threaded port on a hydraulic component. The 37-degree JIC-style flare end provides a metal-to-metal seal at the tube, while the ORB end seals against an O-ring seated in the port boss. This fitting is appropriate for both stationary and mobile hydraulic installations where high-cycle or dynamic pressure loads are present.

Key Features

• 37-degree flare tube end provides a positive metal-to-metal seal with compatible flared tubing
• O-ring Boss (ORB) port end minimizes leak paths at the threaded port connection
• 6000 psi maximum dynamic working pressure rating for high-pressure hydraulic service
• All-steel construction for durability in industrial and mobile equipment environments
• 1/2-20 thread size mates with standard ORB-ported hydraulic components
• Accepts 5/16-inch OD tubing for compact hydraulic circuit routing

Compatibility

Designed as an OEM-style replacement or service fitting for hydraulic systems using 37-degree flare tube connections and ORB-ported components with 1/2-20 thread specifications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the flare seat and ORB port for damage or debris before assembly, and verify the O-ring is properly seated before torquing the ORB end. Follow the equipment manufacturer's torque specifications and applicable industry standards for flared tube and ORB connections.
