Single Hole Round Ceramic Tube Insulators

The following single hole alumina ceramic tube type insulators are available in six inch lengths. The tubes are constructed of a 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 through lines, thermocouple insulators, and in other applications requiring electrical and thermal insulators. Other types are also available - two hole, four hole insulator tubes, and solid rods.

The following ceramic tubes are supplied in 6 inch lengths. Unless otherwise noted they can also be supplied in longer lengths (up to 24 inches long). We can also custom cut shorter lengths to your specifications. Contact us with your specific requirements.

Other sizes available on request

Tolerances on all diameters are ±0.005"
