Your advantages

Today, the O-Ring is the most widely used seal because of its inexpensive production methods and its ease of use. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.

The perfect O-Ring for each purpose

Our O-Rings are both cost-effective and perform highly in almost every environment. No matter if you need metric or inch, standard or custom-made O-Rings – any size of O-Ring seals is available – including giant O-Rings using our Fleximold™ process. Our rubber O-Rings are made of EPDM, FKM, NBR, HNBR, as well as our proprietary FFKM, Isolast®. Special products apart from rubber O-Rings such as O-Rings in PTFE based Turcon® material and Wills Rings® metal O-Rings are also available.

Need an O-Ring seal in a specific material

If you want to find the best material for your application use our online tool:

  • The Material Search allows you to identify compounds that meet specific property requirements and those that comply to specific approvals or standards.
  • The Chemical Compatibility Check allows you to find the level of resistance of material groups to a broad range of media, both fluids or gases including those used within semiconductor manufacturing.

We also offer an e-Learning program on sealing technology.
