      FEATURES

       MOLD COUPLER

      Used in various piping for supplying cooling water of mold

      For connecting, can be finished in one act.

       PNEUMATIC QUICK COUPLINGS
      Uni-directional shut off coupler with an automatic shut off valve built in the socket. Recommended for piping of compressed air connections.
      or connecting, can be finished in one act.

       MEDIUM PRESSURE PNEUAMTIC AND HYDRAULIC QUICK COUPLINGS
      Bi-directional shut off coupler with an automatic shut off valve built in the socket and plug Recommended for piping of chemicals, steam and oil.

       HYDRAULIC QUICK COUPLINGS
      Double shut off couplings are used extensively when it is important to minimize fluid loss upon disconnections. Both halves of coupler, the body and nipple, contain shut off valves, These valves open automatically when the body and nipple are connected, and close automatically when two halves are disconnection-keeping fluid loss to a minimum.
