Carbon Graphite Seal Rings has the advantage of excellent corrosion resistance, self lubricity, high coefficient of heat conductivity. In addition, resin impregnated carbon has low permeability and good thermal conductivity. Resin impregnated Carbon Graphite Seal Faces is the normal rotary seal face material.Â
We have following grades of carbon graphite:Â
*Impregnated Phenolic Resin Graphite
*Impregnated Furan Resin Graphite
*Impregnated Antimony Alloy graphite
*High Purity Graphite
Carbon seals offer the greatest economy and lubricity for sealing non-abrasive products. It's good for clean, abrasive free materials. It self-lubricates to reduce heat and extend service life. It works great with all other seal materials.Â
