USA Made Thermowells - 2L, 5L, 12L & 22L - 24/40 & 45/50

The USA Made Thermowells are tube-shaped laboratory fittings designed to help protect temperature sensors and probes while providing thermal isolation within compatible laboratory equipment. Their specialized design supports temperature measurement applications where the probe needs to be positioned within the process without direct exposure to surrounding conditions.

Available configurations include 24/40 connections for 2L, 5L, 6L, 12L and 22L equipment, along with 45/50 head configurations for 12L and 22L systems. Multiple lengths and configurations make it easier to select a thermowell that matches the vessel or reactor setup.

Please note that the 5L and 6L sizes are not pictured and do not include the top handling prongs. The available options also include a coiled thermowell and dedicated head configurations for compatible laboratory systems.
