Quick coupling socket with hose end, with valve and without shut-off valve, intended for water, chemical, pneumatic installations, etc. Compared to traditional massive couplings with balls and securing sleeve, 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 of the coupling. Applications: chemical photographic processes, battery and accumulator filling installations, sprayers, pneumatic installations, and non-freezing liquids, etc. Length L [mm] – total length. Material: polypropylene. Sealing: EPDM o-ring. Working pressure: up to 4.2 bar. Operating temperature: from 0°C to +71°C.
