Oil Pan and Cylinder Head Cover Gaskets

Low Oil Swell and Low Compression Set Combine in Gaskets of Vamac®

DuPont™ Vamac® ethylene acrylic elastomers are useful in applications where combined heat and oil resistance plus exacting rubber-like mechanical properties are needed.

Properties of DuPont™ Vamac® contributing to long-life, heavy-duty oil pan and Cylinder Head  cover gaskets include:

  • Low melt viscosity, for molding and overmolding of long sections
  • Excellent oil swell resistance, to help keep gasket thickness stable; no tendency to “weep” oil
  • Low compression set
  • Durable service to 165 °C (330 °F) continuous
  • Excellent retention of sealing force at elevated temperatures
