What is ACM?

The ACM (acrylic rubber) O-ring offers good resistance to mineral oils at high temperatures. The O-ring ACM is generally used the most in the automotive industry. The water compatibility and cold flexibility of the O-ring ACM are significantly worse than with NBR.

The advantage of ACM O-ring:

  • Aging
  • Weather conditions
  • Ozone
  • Engine, transmission and AFT oils based on mineral oil
  • Temperature from -30 °C to +160 °C

The disadvantage of ACM O-ring:

  • Hot water, water vapor
  • Acids and alkalis
  • Brake fluids based on glycol
  • Aromatic and chlorinated hydrocarbons
