Galvanised malleable iron 50mm x 20mm reducing couplings are used to connect a 50mm (2") male BSP threaded fitting or pipe end to a 20mm (3/4") male BSP threaded fitting or pipe end. They are suitable for water, air and general pipework applications where a straight female-to-female threaded join needs to reduce in size.
Made from hot dip galvanised malleable iron, this reducing coupling provides a 50mm (2") female BSP thread on one end and a 20mm (3/4") female BSP thread on the other. Use suitable thread sealant or PTFE tape when installing male BSP threads into the coupling.
