Parker KP17700 Steel 90 Elbow 5/8 in Od 3/8-18 Nptf Flare

Product Description

The PARKER KP17700 is a 90-degree flared tube elbow fitting manufactured from steel, designed to connect tubing to NPTF-threaded ports in hydraulic and fluid power systems. It features a 37-degree flare end on the tube side and a 3/8-18 NPTF thread on the port side, providing a leak-resistant metal-to-metal seal under high-pressure conditions. With a maximum working pressure of 5000 psi, this elbow is suited for demanding applications where directional routing changes are required. Licensed plumbers, pipefitters, and hydraulic system technicians typically install this type of fitting during new construction and service work.

The KP17700 is used in hydraulic lines, fluid transfer systems, and compressed-air plumbing where a 90-degree change of direction is needed between a 5/8-inch OD flared tube and an NPTF-threaded port. It is appropriate for both industrial and mobile equipment installations. The 37-degree flare seat conforms to SAE standard flare geometry and provides a positive mechanical seal without relying on thread sealant alone. This fitting is packaged in a quantity of 2 per package.

Key Features

• 37-degree SAE-style flare seat on tube end for metal-to-metal sealing
• 3/8-18 NPTF thread on port end for leak-resistant tapered thread connection
• 5000 psi maximum dynamic working pressure
• Steel construction for durability in high-pressure hydraulic and fluid systems
• 90-degree elbow geometry for compact directional routing changes
• Packaged in quantity of 2 per package

Compatibility

Designed for use with 5/8-inch OD flared tubing and 3/8-18 NPTF-threaded ports in hydraulic, pneumatic, and fluid transfer systems utilizing 37-degree flare connections.

Installation Notes

Installation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Depressurize and isolate the hydraulic or fluid system completely before removing or installing any fittings. Inspect the flare seat and threads for damage before assembly. NPTF threads are designed to seal on the thread form itself, but follow the system manufacturer and applicable code requirements for thread preparation and assembly practices.
