Polished Carbon Seal, Color : Black 20–124 mm

A carbon mechanical seal uses carbon-graphite material for the sealing face, typically paired with a harder counterface (like silicon carbide or tungsten carbide). This seal is designed to fit rotary equipment—such as pumps, compressors, and mixers—and prevent fluid or gas leakage at the shaft interface .

\\\
• \\\

  Temperature Range: From cryogenic conditions to over 500 °F (≈260 °C); specialized grades handle even higher, up to 1150 °F in inert environments .

  \\\
\\\
• \\\

  Pressure & Wear Capability: Engineered to withstand high pressure and mechanical wear. Carbon-graphite materials are selected to endure thermal shock and adhesive or abrasive wear .

  \\\
\\\
• \\\

  Dry Running Tolerance: Self-lubrication enables safer operation when fluid lubrication is intermittent
  

  \\\ Advantages\\\

   

  \\\
  \\\
  1. \\\

     Chemical Compatibility – Resistant to broad fluid types including acids, solvents, and aggressive media .

     \\\
  \\\
  2. \\\

     Low Friction & Energy Efficiency – Naturally lubricious, requiring less power to operate and generating less heat.
