The most common suction hose size used by brigades is the 4” BS336 BSRT. However to ensure that all equipment can be used in an emergency, our BS336 BSRT Round thread adapters can be used so that all 5-1/2” equipment and hoses can be connected, ensuring fire fighters continuity of water supply.
Our BS336 BSRT Round thread adapters are often used in conjunction with emergency water sources, such as water tanks which are normally fitted with our 5-1/2” BSRT round thread flange adaptors which can be found here.
