One-push safe connection and disconnection. The pressure release mechanism eliminates accidental disconnection risks - a next-generation coupler system.
prevoS1 is the safety coupling system developed by Prevost. It enables one-push connection and disconnection, equipped with a safety mechanism that prevents accidental disconnection during work. Combining technical performance with economic benefits, it is adopted in industrial sites worldwide.
Supporting multiple profiles (European, Industrial, Automotive), it accommodates various applications including air tools, paint guns, and blow guns. With a 3-year warranty for long-term reliable use.
Connect and disconnect with just a button press. Safety lock mechanism prevents accidental sudden disconnection.
Multiple profiles including European (DN 7.4), Industrial (DN 10.4), and Automotive to match your site's standards.
Optimized internal flow path design minimizes pressure loss and maximizes air tool performance.
High-quality materials (nickel-plated brass, stainless steel) achieve long service life. Reduces maintenance costs.
A comprehensive coupling system covering 4 fluid categories
Over 267 models. Industrial couplings pursuing safety, flow rate, and durability
Patented one-push safety coupling. Silicone-free, anti-static construction with ATEX Zone 2 certification. 3-year warranty.
