Ao Smith 100111745 Silicone Burner Gasket

Product Description

The AO SMITH 100111745 is a silicone burner gasket designed to seal the burner assembly in water heating systems. Silicone construction provides reliable heat resistance and a durable seal at the burner interface, helping to prevent combustion gas leaks and maintain proper system performance. This type of gasket is a standard service part replaced during burner maintenance, combustion component repairs, or any time the burner assembly is disturbed. Installation is typically performed by licensed plumbers or water heater service technicians.

This gasket is suited for use in residential and light commercial water heater applications where burner assembly sealing is required. It is intended as a direct replacement part for units that use the Type A silicone burner gasket configuration. Service technicians will encounter this part during routine burner pulls, thermocouple replacements, or gas valve service procedures that require the burner to be removed and reinstalled.

Key Features

• Silicone material construction for high-temperature resistance at the burner assembly

Installation Notes

Installation should be performed by a qualified plumber or water heater service technician. Shut off the gas supply and allow the unit to cool completely before removing the burner assembly.
