This Tru-Flate 21-133 hose adapter is made of brass and has a 1/4″ male end
for connecting to threaded pipe conforming to National Pipe Thread (NPT)
standard and a barbed fitting for a hose with a 5/16″ inside diameter. 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 male 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. Brass can be
connected to copper, brass, plastic, aluminum, and welded steel. This fitting
is for use in air line systems.Plews & Edelmann manufactures and distributes a
