Lochinvar & A.O. Smith 100108268 Thermocouple 321142-301 ensuring the system initiates defrostThe Lochinvar & A. O. Smith 100108268 Thermocouple is a critical safety component designed for precise flame rectification in commercial and residential water heating systems. This 24 inch thermocouple provides the necessary millivolt signal to the gas valve, ensuring the pilot flame is established before allowing the main burner to cycle. Engineered for high temperature environments, it is a direct replacement for various Lochinvar pilot assemblies
