Square Silicone 40 Duro O-Rings

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. Silicones have good heat resistance and good cold flexibility.
 

Operating Temperature:

–75°F (–59°C) to 400°F (204°C)

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)
  • Moderate water resistance
  • Diluted salt solutions
  • Ozone, aging and weather resistant.

Not compatible with:

  • Superheated water steam over 250°F (121°C)
