Parker KP81363 Hydraulic Hose Male Rigid Fitting Steel

Product Description

The PARKER KP81363 is a straight male rigid hose fitting designed for use in hydraulic fluid systems. It connects hydraulic hose to threaded ports using a Male O-Ring Boss (ORB) thread interface, providing a leak-resistant seal under pressure. Constructed from steel, this fitting accepts hose with a 0.375 inch inside diameter and uses a 1/2 inch thread size. At 2.11 inches in overall length, it is a compact, fixed-position end fitting suited for use where a swivel is not required. Hydraulic technicians and fluid power mechanics install this fitting during hose assembly fabrication or field replacement of damaged end fittings.

This fitting is intended for hydraulic hose assemblies in industrial and mobile hydraulic applications. The straight profile is appropriate for installations where the hose can be routed without requiring an angled fitting. It is sized for Hose Size 6, corresponding to a 3/8 inch hose diameter, and is compatible with a wide range of Parker hose series commonly used in medium-pressure hydraulic circuits. It is sold in a package of 4 units per package.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic familiar with hose assembly procedures. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Male ORB fittings require correct torque to seat the O-ring properly against the port face — follow the fitting manufacturer torque specifications for the thread size. Inspect the O-ring for damage before assembly and replace it if any cuts or deformation are present.
