The Amtrol 2500-218 Flange Gasket is a replacement sealing component designed for compatible WH7 and WH9 Series BoilerMate tanks. It fits between the tank flange and connected components to create a secure, leak-resistant seal during operation. Replacing older gasket part numbers 2704-403 and 392932, this gasket is used in hydronic heating and domestic hot water systems equipped with Amtrol BoilerMate indirect water heaters. Its durable sealing function helps prevent water leakage, maintain system pressure, protect surrounding components from moisture damage, and support reliable, efficient tank performance during routine operation and maintenance.
