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 cuase 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

In designing an O-Ring Seal, it is best to determine the O-ring compound first, as the selected compound may have significant influence on gland design parameters.

Essentially, the application determines the rubber compound; the primary factor being the fluid to be sealed. The elastomer however, must also resist extrusion when exposed to the maximum anticipated system pressure and be capable of maintaining good physical properties through the full temperature range expected. In dynamic applications, the selected material must also have the toughness and abrasion resistance so important in reciprocating and rotary seals.

Parker's full range of KF type centering rings are available in standard ISO sizes assembled with Parker O-ring materials commonly used in semiconductor wafer processing systems. A variety of material choices are available in stainless steel or aluminum centering ring assemblies. Contact applications engineering for your application needs at 859-335-5101.

Parbak is a Parker standard rubber back-up ring of contoured design. It is intended for use in dynamic and static seal applications.

Features of Parkbak rings:

• Elastic memory permits Parbak rings to be stretched into place for assembly without preconditioning or cutting.
• Continuous construction prevents damage to the o-ring seal.
• Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces.

Back-up ring materials:

• E0652-90
• N0300-90
• N1444-90
• V0709-90
• V0894-90
• V1238-95
• V8588-90
