DOUBLE SHUT OFF COUPLINGS
This series incorporates valves in both the body and nipple halves to prevent fluid loss when the coupling is disconnected. These couplings are normally referred to as "hydraulic couplings", but they are used extensively with other media where fluid loss on disconnect is objectionable. Available in steel, brass, and 303 stainless steel. Body size 1/4" steel, rated to 5,000 psi.
