Copper Gaskets

Copper gaskets are a vital part of any UHV system with CF flanges as they act as the single use compressible seal between the two knife edges. VSM Instruments is your one stop shop for gaskets in any size please ask us for a quote.

Key Features


Our product range includes the following types

  • Standard copper gaskets

 

  • Annealed copper gaskets
    • can be preferable for mounting viewports as they are softer so less likely to cause the viewport to crack on tightening

 

  • Silver plated copper gaskets
      • Often used for applications where the system is baked frequently and to high temperature as the silver plating prevents oxidation of the copper which can eventually cause small leaks.
  • Blank copper gaskets
    • For special applications, these gaskets do not have a central hole so can be used to temporarily provide a barrier between both sides of a flange. They can also be drilled with a small aperture in the centre by the user to limit the conductance from one side of the flange to the other.

GVCG Series standard copper gaskets

These OHFC (oxygen-free) copper gaskets are the every-day choice for sealing standard flanges where no high temperature baking or special viewports are being mounted. They are the lowest cost option, and the default for many customers.

GVCGA Series annealed copper gaskets

These OHFC (oxygen-free) copper gaskets are annealed to make them softer. This results in a lower tightening torque requirement for fragile components such as viewports.

GVCGB Series blank copper gaskets

These OHFC (oxygen-free) copper gaskets solid without a central hole. Applications include blocking the pathway between two flanges or to allow the user to drill a smaller hole to reduce the conductance between two parts of the chamber.

GVCGS Series silver plated copper gaskets

These OHFC (oxygen-free) copper gaskets are silver plated to prevent oxidation at high temperatures, making them ideal for systems which are frequently baked at high temperature. Oxidation of the gasket can eventually cause leakage, so the choice of silver plated gaskets, while more expensive is sometimes a price worth paying for reduced down-time and system reliability.
