Accu-Glass Products Inc. offers a complete line of elctrical breaks designed for vacuum applications requiring cryogenic, water, and vacuum environments.  Cryogenic an vacuum breaks consist of ceramic insulating tubes with metal tubes brazed to each end and welded to ISO or CF flanges.  Water breaks consist of ceramic tubes brazed to copper tubes that can be easily brazed to existing copper tubes.  The central ceramic tube provides electrical isolation between the conductive metal ends.  If the breaks are used between two rigid components, a bellows should be used in the system to reduce mechanical stress that may cause the ceramic to break.

  Accu-Glass Products electrical breaks are all suitable for service in ultrahigh vacuum environments.  Cryogenic and vacuum breaks are not suitable for water service because of corrosion, while water and vacuum breaks are not suitable for cyrogenic service because of expansion differentials and material embrittlement.

  All breaks are bakeable to 450ºC for short term.  Long term will cause oxidation of the metals exposed to air.
