Parker KP81290 Male Sae 37 Jic Rigid Fitting 3/8 in

Product Description

The PARKER KP81290 is a male SAE 37-degree JIC rigid fitting designed for use with hydraulic hose assemblies in fluid power systems. Constructed from steel, this straight-configuration fitting uses a 7/8-14 threaded connection and is sized for 3/8-inch (0.375-inch ID) hose. With an overall length of 2.4 inches, it provides a compact, reliable end termination for medium-pressure hydraulic lines. It is installed by hydraulic system technicians and maintenance professionals working on mobile, industrial, and stationary hydraulic equipment. The JIC 37-degree flare seat delivers a metal-to-metal seal that resists vibration loosening in demanding service environments.

This fitting is suited for straight-run hose terminations in hydraulic circuits requiring a standard JIC male end connection. It is compatible with a wide range of Parker hose series including 187, 302, 304, 387, 422, 424, 426, 436, 471TC, 471ST, 472TC, 482TC, 482ST, 487, 722, 787, 797, and 881 hoses. Typical applications include construction equipment, agricultural machinery, and industrial hydraulic power units where reliable hose-to-port connections are critical. This fitting is sold in packages of 4 with a minimum order quantity of 1.

Installation Notes

Installation should be performed by a qualified hydraulic technician. Depressurize the hydraulic system completely and allow it to cool before removing or installing any fittings. Inspect the JIC flare seat and mating port for nicks or contamination before assembly. Tighten to the fitting manufacturer-specified torque using a calibrated torque wrench; do not use thread sealant on JIC flare connections, as the seal is made at the flare face.
