AirConnection can be made smoothly
regardless of the existing pressure
inside the socket.
• Push-to-connect operation. Easy one-hand operation.
• Built-in sleeve lock mechanism prevents accidental disconnection of Cuplas,
ensuring safe operation.
• Upon completion of sleeve locking the valve will open to supply air.
• When the sleeve is turned back to its original position, the valve is closed
and purges residual air pressure in the plug without unpleasant popping
noise and hose whip motion on disconnection.
• Even after connection, valve opening/closing control is possible.
• Flow rate increases by approximately 20% over that of Hi Cupla Model 400SM.
• Can be connected with plugs for Hi Cupla Models 400, 600 and 800.

4. Disconnection
Disconnection can be made without unpleasant popping noise and hose whip motion due to noresidual air pressure inside the plug.

Before use, please be sure to read “Safety Guide” described at the end of this book and “Instruction Sheet” that comes with the products.
