Mac-Weld tri-clamp thermowells are of heavy duty design to withstand the challenging environments they have to operate in.

Our tri-clamp (or sanitary) thermowells are designed and manufactured 100% in-house, and are made to accept standard and custom made thermometers, thermocouples, bulbs and RTD’s.

Designed for food processing or pharmaceutical production. Sanitary thermowells are typically used when contaminants could collect in exposed threads, such as pharmaceutical or food processing production. The polish and large radius between the stem and face help support easy cleaning.
