Description
Overview:
The Flange Gasket for Honda WB30-series 3 inch (76.2 mm) water pumps is a flat sealing ring used to create a tight, leak-free joint at the pump flange. Made from durable, water-resistant gasket material, it sits between mating faces on the pump housing and pipework or adapters to prevent air and water leaks. This helps the pump hold prime and maintain correct flow and pressure during operation. Referenced by Honda OEM No. 78114-YB4-000, it is designed to match the dimensions and profile required on the WB30 family, including WB30XT2 and WB30XT3. Ideal for routine maintenance or repairs, it restores sealing performance when the flange joint has been disturbed, fasteners retorqued, or an old gasket shows signs of wear.
