This hose fitting adapter has a male end for connecting to threaded pipe conforming to National Pipe Thread (NPT) standards and a barbed fitting for connecting to a hose. The barbed fitting on one end creates a tight seal on flexible or semi-rigid hose when used with a hose clamp or crimp sleeve or ferrule (sold separately), and a male NPT connector on the other end connects to threaded pipe to form a tight, fixed connection This fitting is made of stainless steel for corrosion resistance, ductility at high temperatures, and low magnetic permeability.
