Parker KP81288 Male Rigid Hydraulic Hose Fitting 3/8 in

Product Description

The PARKER KP81288 is a male rigid hydraulic hose fitting designed for use with a wide range of Parker hydraulic hoses. Constructed from steel with a straight shape and threaded Male JIC connection, this fitting attaches hose ends securely to hydraulic system ports and components. It accommodates a 0.375 inch inside diameter hose in the 3/8 inch hose size. With an overall length of 2.36 inches, it provides a compact, low-profile connection suitable for high-pressure hydraulic circuits. Licensed HVAC technicians, fluid power mechanics, and industrial maintenance technicians rely on fittings like this for reliable hose termination in mobile and stationary hydraulic systems.

This fitting is used in hydraulic systems across industrial, mobile equipment, and fluid power applications. The Male JIC threaded interface is a widely adopted connection standard in hydraulic plumbing, making this fitting suitable for both new hose assembly and field replacement work. It ships in a package quantity of four units, making it practical for bench assembly or service van stocking. Applications include hydraulic power units, mobile machinery, and any system routed with Parker hose series listed below.

Installation Notes

Installation should be performed by a qualified fluid power mechanic or hydraulic technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any hose fitting. Use appropriate hose crimping or assembly tooling per Parker assembly guidelines to ensure a leak-free connection. Verify thread engagement and torque to specification using a calibrated torque wrench; do not over-tighten, as this can damage the JIC seating surface.
