Parker KP81361 Hydraulic Hose Male Rigid Fitting 0.25 in

Product Description

The PARKER KP81361 is a male rigid straight fitting designed for hydraulic hose assemblies in demanding fluid-power applications. Manufactured from steel, this fitting features a 9/16-18 male ORB (O-Ring Boss) threaded connection and accepts hoses with a 0.25 inch (1/4 inch, Hose Size 4) inside diameter. At 1.67 inches in overall length, it delivers a compact, low-profile inline termination. The straight geometry suits installations where a direct axial connection to a port or manifold is required. Licensed hydraulic technicians and fluid-power mechanics are the typical installers for this type of fitting.

This fitting is suited for use in industrial and mobile hydraulic systems where a reliable, leak-resistant ORB port connection is needed. The male ORB thread form uses an O-ring face seal against the port boss, reducing the risk of thread-joint leakage under pressure cycling. It is appropriate for both stationary hydraulic power units and mobile equipment hose assemblies operating within the pressure ratings of the compatible Parker hose series listed below.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid-power mechanic familiar with ORB port fitting assembly. Depressurize and isolate the hydraulic circuit completely before removing or installing any fitting. Inspect the O-ring for damage before assembly and lubricate it lightly with clean system fluid prior to torquing into the port boss. Follow the equipment manufacturer and applicable industry standards for assembly torque and hose routing clearances.
