 Applications

 The alumina ceramic tube type insulators are constructed of pure 99% alumina ceramic that has superior gas and vacuum tightness and excellent insulating properties even at elevated temperatures. They are recommended for use in mass spectrometers and other vacuum systems as

feed thru lines, thermocoupleinsulators, and in other applications requiring electrical and thermal insulators.Our products have enjoyed great popularity in and out of china. 

 Four types are available one hole, two hole, four hole insulator tubes, and solid rods.
