Product Description

Thermocouple Protection 99.7% Alumina Ceramic Tube

Mission Ceramic is making high quality ceramic products.
We are make 99.7%  Al2O3  tubes, which max working temperature is 1800ºC
and 95% Al2O3 tubes, which max working temperature is 1500ºC
80% , 70% and 60% purity, we can custom any sizes you need.
According to different usage, our tubes are widely used for furnace tube, thermocouple protection tube, thermocouple insulator and other applications.

Advantage:
1.High purity : 99.7% alumina purity make sure high working temperature.
2.Tight tolerance : we can grind OD to make tight tolerance for easy insulation.
3.Fast delivery : we have large quantity tubes in stock.
4.Inspection: each single tube will be checked before shipping.
5.Low transportation cost : We have long time cooperated shipping agency, which can provide very low prices.
