Alumina Ceramic Insulating tubes are used in Thermocouples Assemblies, high temperature ceramic furnace or vacuum furnace. These ceramic insulating tubes are main made from materials  99.3% alumina.

The ceramic insulator tubes are produced with one, two or more holes, with both ends open. 

The standard tubes have shape and size tolerances according to DIN 40680, DIN 43724 und DIN 43725.

In the case of specific requirements, we are able to deliver tubes with special sizes and precision tolerances.  

We produce our ceramic insulating tubes through extrusion, slip casting, and isostatic pressing.

Insulating Tubes Including:

Extruded Tubing 
Cast Tubing (large diameter tubes) 
Round Double Bore Tubing 
Oval Double Bore Tubing 
Round Four Bore Tubing

• Excellent electrical insulation
