• Immersion wells and compression fittings are available to fit a 1/2-14 or 3/4-14 NPT tapping with a range of insulation depths Immersion wells and compression fittings are available in a variety of lengths and diameter Immersion wells and compression fittings are available in a variety of materials, to suit the application Element holders support the capillary and bulb or an averaging element in duct applications Bulb shields protect the sensing bulb from sun and weather with the bulb installed outdoors Immersion wells allow heat transfer while protecting the sensing bulb from contact with the controlled medium Immersion wells permit removal of the sensing bulb for testing or replacement without draining the system Compression fittings seal the boiler and allow bulb insertion directly into the controlled medium 1/2 in Dia and 4 in insertion 1/2 in NPT Materials include - brass, copper, stainless steel, mild steel or monel

Immersion wells, compression fittings and element holders are used with Aquastat temperature controllers to hold the temperature sensing bulb in the controlled medium. Immersion wells and compression fittings also prevent leakage of the controlled medium.
