This hose fitting is made of brass and connects hose to threaded pipe conforming to the National Pipe Thread (NPT) standard. This adapter is for a fixed connection between plastic or rubber hose and pipe made of copper, nylon, or plastic. A 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 female NPT connector on the other end connects to threaded pipe. This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. The fitting has a temperature range of 32 to 200 degrees F.
