Nitto Kohki Full-Blow SN quick coupler socket optimizes industrial air and inert gas systems. It provides full-flow passage for efficient pneumatic equipment supply, increasing performance and productivity. Simple assembly with a lock nut, service temperature from -5°C to +60°C, safety lock to prevent accidental disconnection and purge operation to reduce operating risks.
Socket with lock nut, allowing the hose to be assembled very easily; observe the internal and external hose dimensions.
It is interchangeable with the entire Nitto line (PH, PF, PM, PN, PAH, SH, SF, SM, SN).
Full-flow compressed-air passage provides better equipment supply.
Specifications:
• Application: air and inert gas;
• Body composition: aluminum;
• Service temperature: -5ºC ~ +60ºC;
• Interchangeability: compatible with all CUPLA Series plugs.
Operation with the valve open or closed
The valve may be open or closed when the coupler is connected.
After connection to the plug, slide sleeve B to open the valve. Full flow is obtained this way.
Slide sleeve B back to the original position to block the flow.
Lock operation
Slide sleeve B toward the plug and turn ring A to lock the lock ring, preventing accidental coupler disconnection.
Purge operation
When sleeve B returns to the original position, the valve closes and all residual air on the plug side is released, reducing accident risks.

Description
The exclusive fully open gate-type valve mechanism provides low pressure loss and high flow, reducing the required source air volume.
-Flow is increased by up to 40% compared with HI CUPLA.
-During connection and disconnection, the valve is closed, allowing connection/disconnection under zero line pressure.
-When the socket sleeve returns to its original position, the purge mechanism releases residual air pressure in the coupler, eliminating unpleasant popping noise and hose whip movement during disconnection.
-The separation-prevention mechanism prevents accidental Cupla disconnection, ensuring safe operation.
-The valve can be opened and closed while the socket and plug are connected.
-Weight is reduced by 30 to 45% compared with conventional Cuplas.
Note: Direct mounting of Full-Blow Cupla on percussive and vibrating tools should be avoided. The exclusive fully open gate-type valve mechanism provides low pressure loss and high flow rate, reducing the required source air volume.
