What is an O-Ring?
An O-ring is a torus, or doughnut-shaped ring, generally molded from an elastomer. O-rings are used primarily for sealing. They are also used as light-duty, mechanical drive belts.
|
Advantages of O-Rings:
|
 | They seal over a wide range of pressure, temperature and tolerance |
|
| Ease of service, no smearing or retightening |
|
| No critical torque on tightening, therefore unlikely to cause structural damage |
|
| O-rings normally require very little room and are light in weight |
|
| In many cases an O-ring can be reused, an advantage over non-elastic flat seals and crushtype gaskets |
|
| The duration of life in the correct application corresponds to the normal aging period of the O-ring material |
|
| O-ring failure is normally gradual and easily identified |
|
| Where differing amounts of compression effect the seal function (as with flat gaskets), and O-ring is not effected because metal to metal contact is generally allowed for |
|
| They are cost-effective |
|
| Our standard O-Ring sizes are available in EPDM E540-80, NBRs N674-70 and N552-90 and FKM V747-75.
