British Instantaneous Couplings are quick-connect fire hose fittings commonly used in the UK and Commonwealth firefighting systems. Featuring a male-female push-and-twist locking mechanism, they allow fast, reliable, and leak-proof connections. Creative offers a wide range of materials (aluminum alloy, brass, stainless steel) and sizes (1.5", 2", 2.5") compliant with BS 336 standards. These couplings are widely used with hydrants, hoses, nozzles, and foam systems in buildings, industrial zones, airports, and military applications.
