Compact Zero Spill Cupla

The Nitto Kohki Compact Zero Spill Cupla is a precision quick-release coupling engineered for pneumatic and hydraulic circuits where fluid loss at disconnection must be eliminated. The zero-spill valve design seals both the plug and socket simultaneously at the moment of separation, reducing residual fluid release to effectively 0 ml - a critical advantage in clean-room assembly, precision machining, and pressure-sensitive automation lines. Operating pressures up to 10 MPa (100 bar) and connection forces reduced by up to 50% compared to standard Cupla variants make this series a benchmark for high-frequency connect/disconnect cycles.

As an authorized distributor for Nitto Kohki, esd.equipment stocks the Compact Zero Spill Cupla series covering both steel and stainless-steel body configurations, compliant with ISO 6150 and JIS B 8381 dimensional standards. The compact form factor - up to 30% shorter than full-size Cupla equivalents - enables direct integration into confined machine spaces without sacrificing rated flow or burst pressure performance.
