The quick coupling socket with hose end, available with or without a shut-off valve, is designed for versatile use in water, chemical, and pneumatic systems, offering a lightweight alternative to traditional heavy couplings with balls and sleeves. Its ergonomic design with a large disconnect button ensures effortless handling and user comfort, while the high-performance valve guarantees excellent flow capacity with minimal leakage. The coupling allows slight hose rotation, reducing the risk of twisting and accidental disconnection, which significantly improves safety and reliability in demanding applications. With outstanding mechanical durability and chemical resistance, it is perfectly suited for environments such as chemical photographic processes, battery and accumulator filling systems, sprayers, pneumatic installations, and non-freezing liquid circuits. Manufactured from robust polysulfone with EPDM o-ring sealing, it withstands working pressures up to 8.6 bar and temperatures ranging from -40°C to +138°C, ensuring long-lasting performance even under extreme conditions. Additionally, it is fully autoclavable, making it an excellent choice for industries requiring the highest standards of hygiene and operational efficiency.
