The Intergas 86474 is a genuine large black Viton front plate seal, designed specifically for Intergas 36kW and 40kW boilers. This is the current approved replacement seal, superseding the older red silicone versions previously listed under part numbers 876597 and 620274, and represents the upgraded specification that Intergas introduced to deliver improved durability and long-term reliability across their boiler range.
This seal sits within the recess on the rear face of the front plate, forming a critical gas-tight barrier between the combustion chamber and the surrounding components of the heat exchanger assembly. Its role is simple but essential, it keeps combustion gases, including potentially harmful carbon monoxide, fully contained within the heat exchanger and directed safely through the flue system. A seal that has deteriorated, compressed flat, or cracked over time can allow flue gases to escape into parts of the boiler where they should never reach, creating a serious safety risk and causing persistent fault codes and reduced boiler performance.
