Thermocouple Putty is a specialized, heat-resistant sealing compound used to ensure accurate temperature readings during Post-Weld Heat Treatment (PWHT). This high-temperature material is applied over the thermocouple tip to shield the junction from direct radiant heat, preventing “false highs” and ensuring the sensor measures the actual metal temperature of the asset rather than the air or the heating element. This category features non-corrosive, industrial-grade putty that remains stable throughout the entire heating and cooling cycle. Essential for critical code compliance, our thermocouple putty provides a simple yet effective way to eliminate thermal interference and maintain the integrity of your temperature data.
