Lochinvar & A.O. Smith 100110898 - Silicone Burner Gasket, 3.75"

Maintain combustion chamber integrity with this high-temperature silicone gasket designed for specific Lochinvar and A.O. Smith hydronic equipment. The 100110898 silicone burner gasket provides a resilient barrier between the burner assembly and the heat exchanger, ensuring that flue gases remain contained and system pressure is correctly regulated. By replacing a worn or brittle seal with this genuine 100110898 replacement, you prevent leakage and maintain the thermal efficiency of the combustion process.

This component utilizes high-grade, heat-resistant silicone material to withstand the extreme thermal cycling inherent in boiler operation. The 3.75-inch diameter ensures a precise mechanical fit, compressing under bolt torque to compensate for minor irregularities on the mounting surface, thereby creating a gas-tight seal that prevents unwanted air infiltration or exhaust discharge.

Key System Performance Baselines:

• Thermal Resilience: Constructed from high-temperature silicone designed to resist degradation from intense burner heat.
• Pressure Integrity: Engineered to provide an airtight seal, maintaining optimal combustion chamber vacuum or pressure.
• Mechanical Fit: Precision-molded 3.75-inch diameter ensures consistent contact across the sealing flange.

⚠️ Application Profile: Compatible with specific Lochinvar and A.O. Smith residential and commercial high-efficiency boilers requiring a 3.75-inch circular burner assembly seal.
