Vacuum Breaks & Envelopes

Various transitions in vacuum systems require voltage isolation. Breaks and Envelopes are all suitable for ultra high vacuum environments. Both are constructed using a high purity alumina insulator sealed into stainless or Kovar sleeve adapters. Vacuum Breaks are available with nominal tube diameters up to 3 inches, and voltage ratings up to 60,000 Volts DC. Standard designs include Weldable, Conflat Flange and Quick Flange adapters.

Vacuum Envelopes are available with nominal tube diameters up to 8 inches, and voltage ratings up to 20,000 Volts DC. Weldable and Conflat Flange adapters are standard.
