Product Description

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor

 

1. Description:

These mullite tubes can repeatedly be exposed to temperature fluctuations without deforming or cracking. They can be used as a protective cover over materials that are moved between hot and cold environments, such as thermocouples. These tubes are fully fired and seal out air and gas in high temperature applications like nonporous alumina. They also resist corrosion from a variety of chemicals. Use them in furnaces, heaters, electrical insulation, and glass- and steel-industry refractories.

 

2. Feature Advantages:

1) Abrasion resistance

2) Impact resistance

3) High precision

4) High stability

5) High welding sealing performance

6) Good wear resistance
