Parker KP81301 Female Jic 37 Deg Swivel Fitting 1/4 in

Product Description

The PARKER KP81301 is a straight female JIC 37-degree swivel fitting designed for hydraulic hose assemblies. Machined from steel, this threaded fitting connects to 0.25-inch inside diameter hoses and uses a 1/2-20 thread size. With an overall length of 2.03 inches, the KP81301 is part of Parker Series 43 and provides a reliable, leak-resistant swivel connection in high-pressure hydraulic systems. Licensed hydraulic technicians and fluid power specialists install this fitting in mobile equipment, industrial machinery, and fluid transfer applications where a female JIC interface is required.

This fitting is designed for use in hydraulic hose assemblies on mobile and stationary equipment where a straight, female JIC swivel end is needed at the hose-to-port connection. The swivel design allows for easier routing and installation without twisting the hose assembly. It is suited for shop fabrication or field repair work on hydraulic lines operating in demanding environments. The 1/4-inch hose diameter sizing makes it appropriate for smaller-bore hydraulic circuits.

Installation Notes

Installation is performed by licensed fluid power technicians or hydraulic system mechanics. Depressurize and isolate the hydraulic circuit fully before disconnecting or assembling any fittings. Use appropriate thread sealant or dry-seal practices as specified by the system design — JIC 37-degree flare connections rely on metal-to-metal seating and do not use pipe thread sealant at the flare interface. Follow applicable fluid power standards and equipment manufacturer guidelines for torque and assembly procedures.
