TorqueUnique full-open gate type valve
mechanism realizes low pressure loss
and high flow rate, which reduces
required source air volume.
• The flow rate is increased by up to 40% more than that of conventional Cuplas.
• During connection and disconnection, the valve is closed, enabling
connection/disconnection under zero line pressure.
• When the sleeve of socket is returned to its original position, the purge
mechanism releases the residual air pressure in the plug, eliminating
unpleasant popping noise and hose whip motion on disconnection.
• Built-in sleeve lock mechanism prevents accidental disconnection of Cuplas,ensuring safe operation.
• The valve can be opened and closed while the socket and plug are connected.
• The weight is reduced by 30 to 45% compared with that of conventional Cuplas.

To mount on urethane hose, slide it over to the hose barb and tighten the nut until it is flush against the hose barb base.
It is recommended that grease is applied to the inside of the nut (threaded part and hose contact part) for easy tightening.

Flow Direction
Fluid must run from socket to plug.

Interchangeability
Can be connected with plugs for Hi Cupla Models 10, 17, 20, 30, and 40.
Interchangeable with all other Hi Cupla Series products. Please see the page for “Hi Cupla
Series Interchangeability.”
Not interchangeable with some plugs of plastic Hi Cupla 250 (discontinued product).

Note: Direct mounting of Full-Blow Cupla to percussive and vibrating tools should be avoided.

How It Works
1. Open the valve

2. Lock the sleeve

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

The flange

Pull the sleeve B
toward the plug.

Rotate the flange counterclockwise
and align themarks.

To disconnect the plug, first turn the flange back to its original position for unlocking and then pull thesleeve B back to the original position. The built-in valve will be closed to purge the residual air pressure.

Sleeve B

Pull back the sleeve B to purge
the residual air pressure.

LockOFFThe valve
closed.

The valveopen.

3. Purge the residual air

Rotate the flange counterclockwise to lock the sleeve B. Without unlocking theplug you cannot disconnect.

LockON

Residual air pressure
Air will be purged out under the sleeve B.
Before use, please be sure to read “Safety Guide” described at the end of this book and “Instruction Sheet” that comes with the products.
