This connector is designed for low-pressure LPG systems and typically fits 8 mm gas hoses with a 1/4" left-hand BSP thread. It uses a push-and-pull quick release mechanism with an integrated self-sealing valve, which automatically shuts off gas flow when disconnected. The unit is compatible with Cadac barbecues and most caravan BBQ point systems, and is manufactured from durable metal components for repeated outdoor use.
