The adaptor is a hinged two-piece ductile iron ring that closes over the groove of the pipe end. Its face is drilled to the flange standard of the equipment, and an EPDM gasket moulded to seal on both the pipe OD and the mating flange face sits inside. Bolting it to a flanged valve or pump creates the joint without welding, which makes equipment removal much easier.
