O-rings

Viton

An O-ring is a torus – a doughnut shaped ring – generally molded from an elastomer. The simplicity of the shape of an O-ring and the reliability of its function is ingenious and that is why they are the most frequently used type of seal. They are economical to manufacture and easy to fit – that makes them unbeatable.

The advantages of O-rings are:

  • they work over a wide range of pressure temperature and tolerances
  • ease of service - no smearing or re-tightening
  • no critical torque on tightening so they're unlikely to cause structural damage
  • o-rings require very little space and are light in weight
  • the duration of life in the correct application corresponds to the normal ageing period of the O-ring material.
