Filled Carbon



Carbon-graphite seal face mixtures are filled with organic and inorganic materials for a variety of reasons that include:

  • Increasing the seal face density.
  • Lowering the sliding friction
  • Increasing the strength

You should be aware that these many of these fillers have poor chemical resistance and are often sensitive to changes in temperature.

With few exceptions, you will be better off using an un-filled carbon seal face. This is a compound of carbon, graphite and nothing else.
