Description
Overview:
This suction flange is a Honda OEM component for 2 in (approx. 50.8 mm) water pumps, used to connect the suction hose securely to the pump body and maintain a reliable seal under working pressure. Built from durable aluminium alloy with a corrosion‐resistant finish, it is suitable for outdoor and wet environments.
