Gasket materials range from metals, fibers, composites and elastomerics. Within each of these categories there are tens or hundreds of variations. Elastomeric materials or “rubber” materials include silicone, chloroprene (Neoprene), EPDM, urethane, and fluoroelastomers (fluorocarbon and fluorosilicone) to name a few. Within each polymer group there are physical variations such as expanded sponges and foams, solids, thermally conductive and electrically conductive. Lastly, many of these materials are molded in 3D shapes or die cut from sheets.

Stockwell Elastomerics has a core competence in commercially available, high performance, elastomeric gasket materials. What does this mean? This means Stockwell Elastomerics offers materials that are readily available to be converted into custom parts for OEMs. “Performance” means quality, engineered materials where the function is paramount.

Below are a few examples of materials and gasket uses/types:

Gasket Materials


  • UV and ozone resistant gasket
  • Outdoor gasket / rain gasketing
  • High and low temperature gasket
  • Low durometer gasket (soft)
  • Long life gasket


  • General purpose gasket
  • Oil resistant gaskets (moderate)
  • Environmental gasketing


  • Outdoor gasket
  • High strength gasket


  • Chemical resistant gasket (fuel)
  • High and low temperature gasket
  • UV and ozone resistant gasketing

Selecting the proper material for performance and cost can be difficult and tedious. Stockwell Elastomerics’ Applications Engineers can help narrow the options and discuss applications details. To contact Stockwell Elastomerics, please call 215-335-3005, email service@stockwell.comor visit
