ACV Gasket for dual ceramic ignitor 557A0163

The ACV Gasket for dual ceramic ignitor 557A0163 is a sealing component used to create a gas-tight seal around the penetration point of a dual ceramic ignitor assembly in burners or boilers. It prevents leakage of flue gases or combustion air and protects electrical connections from contamination. This gasket is designed for exact fit and high temperature resistance, suitable for high heat applications. It is compatible with ACV Prestige 18 MK2, Prestige 24 MK2, Prestige 32 MK2, HeatMaster 60, and HeatMaster 85 models. The gasket is not reusable and should be replaced if signs of cracking or hardening appear.

Parts of this type are selected by matching the exact dimensions and material specification required for the temperature and medium at the mounting location. When replacing, verify that the gasket profile matches the recess or groove on the ignitor flange or the burner plate. Do not reuse an old gasket; any deformation can compromise the seal. If the gasket is part of a repair kit, the kit is compiled for a specific ignitor series and is not interchangeable with other variants.

A worn gasket can lead to false flame signals or ignition failures. Signs of deterioration include cracking or hardening. During routine service, inspect the gasket and replace it whenever the ignitor is removed or if such signs are present.
