Termopozo 1 / 2» De Dietrich 7733688

The thermowell 1/2" is a protective sleeve designed to house temperature sensors in boiler and burner systems. With a 1/2-inch thread, it allows for easy installation into tanks, pipes, or boiler bodies. This thermowell shields the sensor from direct contact with the medium, ensuring accurate temperature readings while extending sensor life. It is a common spare part for heating equipment maintenance and repair, compatible with many standard sensor probes. Replace a damaged or missing thermowell to maintain precise temperature control.
