O-Ring Compounds

o-ring compounds

Seal and Design offers a wide range of rubber compounds also know as elastomers. Elastomers consist of both synthetic and natural materials, and are formulated to have a wide array of physical properties. Different compounds are better suited for a variety of applications, depending primarily on the compound’s exposure to fluids, heat, and pressure.

General compounds exist for applications with typical environments, while highly engineered compounds exist for the most demanding environments and applications. When an o-ring is required in automotive, aerospace, chemical processing, or pharmaceutical application, Seal & Design has access to the best compound for the job.

Teflon Encapsulated O-Rings

Teflon Encapsulated O-Rings Datasheet (PDF)

Teflon Encapsulated o-rings consist of a seamless and uniform Teflon® FEP/PFA encapsulation/jacket which completely encloses a core material of either silicone or Viton® elastomers. The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. Compared with solid o-rings, Teflon-encapsulated o-rings function in a broader range of environments, and have a temperature range from -60°C/-75°F to +205°C/400°F.

Ethylene Acrylic (AEM, Dupont VAMAC®)

Developed as a lower temperature version of Polyacrylate. The temperature range is -40°F to 325°F. It typically has higher swell than Polyacrylate in automatic transmission fluids and power steering fluids.
