Parker KP81355 Male Npt Swivel Fitting 0.375 in Id Steel

Product Description

The PARKER KP81355 is a male NPT swivel fitting designed for use with hydraulic hose assemblies in fluid power systems. Built from steel with a straight shape and threaded connection type, this fitting features a male NPTF shaft and accepts hoses with a 3/8 inch (0.375 inch) inside diameter. The overall length is 3.3 inches, and the thread size is 1/2-14. It is sold in packages of 4 and is suited for installation by hydraulic system technicians and fluid power mechanics working on industrial or mobile equipment applications.

This fitting is intended for straight-run hose terminations where a male NPT swivel connection is required. The swivel design allows for rotational adjustment during assembly, reducing hose twist and simplifying routing in tight or complex plumbing layouts. It is appropriate for use in both new hydraulic circuit builds and replacement service work on existing assemblies. Typical installations are found in industrial machinery, mobile equipment, and fluid transfer systems where NPT-threaded ports are standard.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power mechanic. Depressurize and isolate the hydraulic circuit completely before disconnecting or installing any fittings. Use appropriate thread sealant compatible with hydraulic fluids on the NPT threads. Torque to the fitting manufacturer and system designer specifications — do not over-tighten, as this can damage the NPTF threads or fitting body.
