O-Rings/ Seal Kits

 

 

 

O-Ring Seal Kits are made from a high-quality
Nitrile rubber or a high-temperature fluoroelastomer. These seal kits
are available in inch and metric sizes.

 

'O' Rings
‘O’ Rings are ring-shaped seals of circular section used in an infinite number of applications. The polymers available ensure that temperatures in excess of 300° C can be accommodated. They can also withstand most chemicals and work at extremely low temperatures.
For pressures in excess of 100 bar PTFE back-up rings are recommended to ensure that ‘O’ Rings resist extrusion.


Materials available are:
Nitrile
Viton
Silicone
PTFE
Polyurethane



The hardness of standard ‘O’ Ring is normally 70 IRHD but this can be increased or decreased to suit customers’ needs.
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 duratio 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 engineers can help you determine which O-Ring has the right physical limits for your unique application. To further improve your operating productivity, we can also assist in determining proper gland design, material selection and back-up rings that will serve your needs.
