How It Works 2. Lock the sleeve 3. Purge the residual air

1. Open the valve Rotate the flange counterclockwise to lock the sleeve B. Without unlocking the To disconnect the plug, first turn the flange back to its original position for unlocking and then pull the
plug you cannot disconnect. sleeve B back to the original position. The built-in valve will be closed to purge the residual air pressure.
Only after connection with the plug, you can slide the socket sleeve B toward
the plug in order to open the built-in valve. Full flow path is then obtained.

Sleeve B Pull the sleeve B The flange Rotate the flange counterclockwise Sleeve B Pull back the sleeve B to purge

- Built-in “lock mechanism” locks the sleeve upon connection,
thus prevents accidental disconnection. Suitability for Vacuum
Not suitable for vacuum application in either connected or disconnected condition.
- Just push the plug into the socket for simple connection.
- Spiral polyurethane coil hoses processed from straight tube have

self-recoiling feature. (Only with HI CUPLA ACE)
- A Sleeve Cover is attached to "NK CUPLA HOSE with FULL BLOW

CUPLA", which reduces the impact on CUPLA and improves
operability.

Note: Either socket or plug of HYPER HSP CUPLA must be used on the line where the residual pressure remains. The counterpart of HYPER HSP must be either plug or socket of standard HSP CUPLA.
HYPER HSP CUPLA can be connected under the residual pressure in the line,but cannot during pressurizing. It may lead to incomplete connection, durability deterioration or possible valve fly out.
