The Amtrol 2500-218 Flange Gasket is a sealing element that is used to ensure a leak-free connection between the tank flange interface. The gasket is a compressed seal between the flange surfaces of the water heater tank and the connected components that ensure that fluid does not leak out but it does not compromise the pressure integrity in hydronic circuits that are used in HVAC systems. Its profile of sealing is shaped in accordance with the flange mounting pattern of WH7 and WH9 Boilermate tanks. It is located at the point of tank flange connection, which seal the water pathway correctly when the system is in operation.

What maintenance is required for the Amtrol 2500-218 Flange Gasket?

Inspect the gasket regularly for cracks, wear, or compression damage. Ensure it is seated correctly between flanges to prevent leaks. Replace immediately if signs of deterioration appear, and avoid overtightening bolts to maintain a proper seal.

  • Warping or deformation from heat exposure.
  • Cracking or splitting of the gasket material.
  • Difficulty achieving a proper seal after repeated use.

Installation Steps

Step 1: Turn off the boiler system and allow the tank to cool completely to avoid burns.

Step 2: Drain the tank to below the flange level to prevent leaks.

Step 3: Remove the old gasket carefully, cleaning the flange surface of residue and debris.
