Parker KP81280 Hydraulic Hose Mpt Fitting 0.625 in Nptf

Product Description

The PARKER KP81280 is a straight male pipe thread (MPT) fitting designed for hydraulic hose assemblies. It connects 5/8-inch (0.625-inch) ID hoses to threaded ports using a 3/4-14 NPTF thread form, which provides a pressure-tight metal-to-metal seal without relying solely on sealant. Constructed from steel for durability in high-pressure hydraulic environments, this fitting measures 2.87 inches in overall length. It belongs to Parker's Series 43 fitting line and is intended for installation by hydraulic system technicians and fluid power specialists in industrial and mobile equipment applications.

This fitting is suited for hydraulic hose assemblies in mobile equipment, industrial machinery, and fluid power systems where a threaded pipe connection is required at one end. It is compatible with a wide range of Parker hose series, making it a practical stocking item for shops that service multiple hose types. The straight geometry simplifies routing in applications where an angled adapter is not needed.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power assembly procedures. Depressurize and drain the hydraulic system completely before removing or installing any fittings. NPTF threads rely on thread-form interference for sealing; inspect threads for damage before assembly and apply thread sealant per system requirements. Torque to the hose and port manufacturer specifications using appropriate hydraulic fitting assembly tools.
