Advantages of an O-Ring

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 crush-type 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), an O-ring is not effected because metal to metal contact is generally allowed for.

• They are cost-effective.
