Parker KP81311 Female Jic 37 Deg Swivel Fitting 5/8 in

Product Description

The PARKER KP81311 is a female JIC 37-degree swivel fitting designed for use with hydraulic hose assemblies in high-pressure fluid power systems. Built from steel with a threaded connection type, this straight-body fitting accepts hose with a 0.625 inch inside diameter (hose size 10) and features a 5/8 inch thread size. The swivel design allows the fitting to rotate during assembly, reducing hose twist and simplifying installation in tight routing environments. It is installed by licensed hydraulic technicians and fluid power mechanics on mobile equipment, industrial machinery, and stationary hydraulic systems.

This fitting is suited for hydraulic plumbing applications where a JIC 37-degree flare connection is required at the hose end. The straight configuration makes it appropriate for standard inline routing without angled adapters. Its steel construction handles the pressures common in industrial and mobile hydraulic circuits. The fitting ships in a package quantity of four, making it practical for shop stocking and multi-point service work on equipment requiring multiple hose end replacements.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with JIC flare fitting assembly procedures. Always depressurize and bleed down the hydraulic system before disconnecting or installing any hose end fittings. Hand-tighten the swivel nut onto the mating male JIC seat before applying final torque with an appropriately sized open-end or flare-nut wrench. Do not over-torque — consult the hose assembly manufacturer guidelines for final assembly torque values appropriate to the thread size.
