Carbon & Graphite Gaskets

Mercer Gasket & Shim’s carbon fiber and graphite gaskets are among the most reliable gasket options available for high-pressure, high-temperature applications involving steam.

In addition to saturated steam, our carbon fiber and graphite gaskets are used against a wide variety of acids, alkalis and salt solutions, organic compounds, and heat transfer fluids at high temperatures.

Mercer’s carbon fiber gaskets offer wide chemical resistance, and their high thermal conductivity ensures rapid heat dissipation and allows high temperature capability (except in oxidizing atmospheres). Our gaskets made from graphite flake material excel in extreme conditions, withstanding heat, pressure and aggressive/corrosive chemical environments to retain stability and sealing performance in high temperatures and pressure fluctuations. Graphite gaskets are often reinforced with a stainless steel insert.

At Mercer, we utilize high-grade carbon and graphite fiber materials to ensure superior integrity and sealing performance in our gaskets:

  • Carbon or Graphite/Nitrile
  • Carbon or Graphite/SBR
  • Pure Flexible Graphite
  • Pure Flexible Graphite – Metal Inserted

Mercer carries Garlock and Thermoseal brands of carbon fiber and graphite gasket materials.
