Quick-connect socket with internal BSP thread, with and without shut-off valve, resistant to ultraviolet radiation, intended for water, chemical, pneumatic installations, etc. Compared to traditional massive couplings with balls and protective sleeves, it has a very low weight. Ergonomic shape and large disconnect button enhance manipulation comfort and ease of use. Very efficient valve allows for high flow rates and minimal leakage. This coupling also allows for slight rotation of the connected hose, preventing twisting and accidental disconnection. Applications: chemical photographic processes, battery and accumulator filling installations, sprayers, pneumatic systems, and non-freezing liquids, etc. It features high mechanical strength and chemical resistance. Suitable for autoclaving. Length L [mm] – total length. Material: UV polysulfone. Sealing: EPDM o-ring. Working pressure: up to 8.6 bar. Operating temperature: from -40°C to +138°C.
