Conductive Silicone O-Ring 70 Duro Black

These O-Rings draw in static and electrical currents to prevent electromagnetic interference and static shock which can damage sensitive part. EMI O-rings are not the same as flat EMI washer gaskets. They’re also different than jam nut seals, D-subminiature gaskets and other EMI gaskets used for sealing and shielding. At the most basic level, EMI O-rings are toroidal or donut-shaped EMI extrusions. This supports their usage in demanding applications where temperature, pressure, and tolerances could cause other types of elastomeric gaskets (such as flat washers) to fail.

The term silicone covers a large group of materials in which vinyl-methyl-silicone (VMQ) is often the central ingredient. Silicone elastomers as a group have relatively low tensile strength, poor tear and wear resistance. However, they have many useful properties as well. Silicone has a good heat resistance, good cold flexibility, and good ozone and weather resistance as well as good insulating and physiologically neutral properties.

Chemical Resistance:

  • Engine and transmission oil (e.g.: ASTM oil No.1)
  • Animal and vegetable oil and grease
  • Brake fluid (non-petroleum base)
  • Fire-resistant hydraulic fluid, HFD-R and HFD-S
  • High molecular weight chlorinated aromatic hydrocarbons (including flame-resistant insulators, and coolant for transformers)
  • Beer, Coffee, Whiskey and Milk
  • Moderate water resistance
  • Diluted salt solutions
  • Sea Water
  • Ozone, aging and weather resistant.

Not Compatible with:

  • Silicone Grease and Oils
  • Super-heated water steam over 250°F (121°C)
  • Acids and alkalis
  • Low molecular weight chlorinated hydrocarbons (trichloroethylene)
  • Chlorine wet or dry
  • Aromatic mineral oil
  • Transmission Fluid
  • Hydrocarbon based fuels
  • Diesel Oil
  • Aromatic hydrocarbons (benzene, toluene).
