Protection tubes for thermometers with union nut
Our protection tube range includes protection tubes made of several pieces being soldered or welded together and protection tubes turned from a single piece. The protection tubes are either screwed or welded into position.
We manufacture thermometers with internal or external threads which can also be combined with neck tubes to bridge thicker insulating layers. Protection tubes made of various materials are available. SIKA thermometer protection tubes are based on the DIN standard 43772. This results in the various protection tube designs and shapes.
