1/4" MNPT hose end with 1/4" ID hose offers a full swivel. The 360 degree full swivel prevents hose from kinking. A hose clamp may also be used but is not as desirable. Brass hose fittings are used to assemble new hoses or replace old fittings on hoses. For best results and professional finished product the hose end should be secured with a crimped ferrule.
