350 Coupler
For hydraulic pressures up to 34.5 Mpa {352 kgf/cm2}
- Airless valve shut-off design greatly reduces
air admixture! - Ideal for hydraulic lines with larger pressure
fluctuations - Both socket and plug have built in automatic
shut-off valves to prevent fluid spill out when
disconnected. Easy to handle.

Full Blow Coupler
Unique 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 then 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 an unpleasant popping noise and a hose whip back motion on disconnection.
