Parker 11343-4-6 Male Nptf Pipe Swivel Fitting 3/8 in

Product Description

The PARKER 11343-4-6 is a male NPTF pipe swivel fitting designed for use in hydraulic hose assemblies. Built from steel with a straight, threaded configuration, this fitting connects hose lines to threaded ports using a National Pipe Taper Fuel thread form for leak-resistant sealing under pressure. It fits hoses with a 0.375 inch inside diameter (hose size 6) and carries a 1/4 inch thread size. With an overall length of 3.01 inches, it is a compact, field-proven component used by hydraulic system technicians across mobile and industrial applications. It ships individually and is available in single-unit quantities.

This fitting is used in hydraulic hose routing where a swivel connection is needed at a male NPTF pipe port. The swivel design reduces torque transfer to the hose during installation and allows for easier line routing in tight or angled installations. It is suited for both original equipment assembly and service replacement work on hydraulic systems in mobile machinery, industrial equipment, and fluid power circuits. A licensed or trained hydraulic technician typically handles installation in pressure-rated applications.

Installation Notes

Installation should be performed by a qualified hydraulic technician familiar with fluid power system assembly and pressure ratings. Always depressurize and lock out the hydraulic system before removing or installing any fittings. NPTF threads rely on thread-form interference for sealing — inspect threads for damage before assembly and follow the fitting manufacturer's recommended assembly practice. Do not overtighten, as this can crack fittings or distort thread sealing surfaces.
