Parker KP81275 Hydraulic Hose Male Rigid Fitting 3/8 Nptf

Product Description

The PARKER KP81275 is a male rigid straight fitting designed for hydraulic hose assemblies. It connects 1/2-inch (0.5 inch) ID hoses to threaded ports using a 3/8-inch NPTF thread, creating a leak-resistant, pressure-rated joint without swivel movement. Constructed from steel, this fitting delivers the durability required for high-pressure hydraulic circuits in industrial and mobile equipment. The straight configuration and threaded connection type make it a direct-fit option for inline hose terminations. Overall length is 2.59 inches. This fitting is sold in a package quantity of four units, with a minimum order quantity of one.

This fitting is suited for hydraulic systems in mobile machinery, industrial equipment, and fluid power assemblies where rigid, non-swivel hose connections are required. It is typically installed by hydraulic technicians and fluid power specialists during hose assembly fabrication, system builds, or field hose replacements. NPTF threading provides a dry-seal connection, which reduces reliance on additional thread sealants in many applications.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and isolate the hydraulic circuit completely before disconnecting or assembling any fittings. NPTF threads are designed as dry-seal connections; inspect threads for damage before assembly and apply thread sealant only if required by the system specification. Torque fittings according to the hose and fitting manufacturer guidelines for the applicable thread size and system pressure rating.
