Our brass tank connection sets are designed to fit the respective brass threaded bsp outlets on our water tanks. Always check that the inch size of the tank connection set matches the brass threaded BSP outlet on the water tank and decide which hose size the tank connection should end in. We offer all brass tank connection sets in straight or bend versions for hose sizes of 10, 13, 25 and 32mm internal diameter. Only hand-tighten the parts for installation on the brass threaded outlet and ensure that all external threads are sealed with Teflon tape.
