Technical specifications

Most conventional graphite seals are not resistant to the effects of oxidation at very high temperatures. In order to meet the specifications of a high temperature gasket, Leader designed and developed LeaderTHERM gaskets. 

LeaderTHERM withstands extreme temperatures

These high temperature gaskets have a unique composition that makes them resistant to oxidation, solvents, acids, bases and mineral oils. Thanks to the addition of Mica, LeaderTHERM withstands temperatures up to 1800 °F. LeaderTHERM is used in gas turbines, oil burners and heat exchangers.

Advantages of high temperature gaskets

Other than the resistance to extremely high temperatures (up to 1800 °F), high temperature gaskets (or heat exchanger gaskets) have many more advantages. For instance:

  • They are made with a high-density inner ring that increases sealability many times over traditional flexible graphite.
  • These gaskets are the most economical way of meeting low emission requirements.
  • High temperature gaskets utilize a unique corrugation pattern which increases the depth of the grooves and the pitch at the peak of the corrugation.
