Nitrile rubber custom gaskets:

In addition to custom rubber seals, A.J. Rubber & Sponge Ltd. also manufactures nitrile rubber custom gaskets for a variety of industrial and commercial applications. Our nitrile rubber custom gaskets physical and chemical properties can vary depending on the composition of the specific acrylonitrile species involved. As an example, the higher the concentration of acrylonitrile in the polymer, the higher the nitrile rubber custom gaskets resistance to oils will be. This particular property, however, can compromise the flexibility of the custom rubber gasket and make it more rigid.

Also referred to as buna-n rubber, nitrile rubber belongs to a family of synthetic rubber custom gasket materials that are comprised of a copolymer of acrylonitrile and butadiene. Nitrile rubber custom gaskets tend to be highly resistant to:

  • Grease
  • Oil (natural & synthetic)
  • Gasoline
  • Diesel
