The quick-connect socket with internal BSP thread, available with or without a shut-off valve, is designed for maximum versatility in water, chemical, and pneumatic systems. Manufactured from UV-resistant polysulfone and sealed with a durable EPDM o-ring, it ensures long-lasting performance even under demanding conditions. Its lightweight construction, compared to traditional heavy couplings with balls and sleeves, makes handling effortless, while the ergonomic shape and large disconnect button provide exceptional comfort and intuitive operation. The high-efficiency valve guarantees excellent flow capacity with minimal leakage, and the innovative design allows slight hose rotation, preventing twisting and accidental disconnection. Withstanding pressures up to 8.6 bar and operating temperatures from -40°C to +138°C, this coupling is ideal for applications such as chemical photographic processes, battery and accumulator filling, sprayers, pneumatic systems, and installations with non-freezing liquids. Its outstanding mechanical strength, chemical resistance, and suitability for autoclaving make it a reliable and professional solution for industries requiring safety, efficiency, and durability.
