Description
The Emerson Climate-White Rodgers F89-0027 Well Brass 1/2 inch NPT is an immersion well designed to house sensing bulbs for temperature control system. It provides a sealed brass interface that allows the accurate temperature transfer from the medium to the sensing elements while keeping the sensor isolated from direct contact with the fluids. It is compatible with models such as 1609, 1629, and 2A23, ensuring the proper fitment within those control setups. It is installed in boiler and hydronic control assemblies in HVAC systems, and it operates as a protective sensing sleeve that supports the accurate temperature monitoring for stable control operations.
