FEP Encapsulated O-rings

While choosing an O-ring for your application, a great deal of significance ought to be set on the material of the seal being utilized. Since an appropriate fixing activity is exceptionally reliant on the state of your O-ring, it is significant that an O-ring material be picked to best suit the working condition of your application. A portion of the regular materials used to make O-rings are nitrile elastic or Buna-N, Viton(r), silicone elastic, neoprene, and PTFE or Teflon(r).

Picking an O-ring material is reliant on various variables, yet two of the most basic elements are the working temperature run that O-rings are exposed to and the various synthetic concoctions they might be presented to. Some extra factors that assume a job in the determination of an O-ring material incorporate protection from tearing and scraped area, and daylight or maturing. Since most O-ring materials respond contrastingly to assorted conditions just as synthetic concoctions, every material has its very own points of interest and detriments. Silicone O-Rings

Nitrile Rubber:

One of the most widely recognized materials used to make O-rings is nitrile elastic or Buna-N, which is a manufactured elastic copolymer. This material has great protection from water, pressure driven liquids, solvents, oils and other oil based goods. This element, combined with its working temperature scope of between – 65 degrees F to +275 degrees F, has made nitrile elastic one of the most broadly utilized elastomers to make O-ring seals. Notwithstanding, this material has its impediments; nitrile is for the most part not prescribed for applications where it may be presented to daylight and ozone, just as specific synthetic compounds, which incorporate ketones, esters, and sweet-smelling hydrocarbons. Moreover, its defenselessness to ozone likewise makes it important that nitrile elastic seals are not put away close to electric engines that ordinarily create ozone. Its high protection from oil based commodities and sensible protection from temperature has prompted Nitrile elastic O-rings turning into the principal decision for different applications in the vehicle business.

Silicone Rubber:

Silicone rubbers are a gathering of elastomeric polymers created from silicon, hydrogen, oxygen, and carbon. Silicones for the most part have poor protection from scraped area and tearing, just as low rigidity in addition to high co-productive of contact – highlights that make them unsatisfactory for dynamic fixing applications. Be that as it may, its outstanding protection from outrageous temperatures, running from as low as – 150 degrees F to as high as +500 degrees F, makes it perfect for applications where seals are presented to high dry warms, as in car parts and cookware.


Viton(r) is another engineered elastic regularly utilized for making O-ring seals, which is a sort of FKM elastomer. This current elastomer’s great protection from solvents and oils, just as its protection from expansive working temperature ranges, has made it a well known for use in various applications. In spite of the fact that its working temperature ranges from – 10 to +400 degrees F, seals produced using this material are referred to withstand temperatures as high as +600 degrees F for brief occasions. This mix of properties settles on Viton a perfect decision for high temperature applications just as applications presented to a wide range of liquids. One such application that has received Viton O-rings is SCUBA jumping, where the O-ring seals are utilized in the jumper’s air tank. In any case, however Viton is good with most hydrocarbons, it is commonly not perfect with ketones and natural acids.


One fluoropolymer ordinarily used to produce O-rings is PTFE, or Teflon(r), as it is generally known. PTFE is one of the most artificially inactive materials used to make O-rings and amazingly impervious to oils, solvents, bases, acids, steam, and different synthetic substances. Its unmatched protection from scraped area and tearing makes it perfect for dynamic fixing applications. Nonetheless, there are scarcely any downsides to utilizing PTFE O-rings. The first is their powerlessness to be packed as successfully as other generally utilized O-ring materials, which converts into wasteful fixing. The other significant burden of this material is its poor virus stream attributes under consistent strain. In any case, its substance opposition and low coefficient of grating has made it a well known fixing alternative in numerous valves and different applications.


Neoprene is one more engineered elastic that is normally used to make O-ring seals. This elastomer is impervious to creature and vegetable fats, just as most oils and solvents. In any case, O-ring seals produced using this material are by and large not prescribed for applications that include introduction to ketones, esters, fragrant hydrocarbons, and solid oxidizing acids.

Characteristic Rubber:

At present, characteristic elastic O-rings are once in a while utilized because of the coming of manufactured elastomers, for example, Nitrile elastic and Viton. Regular elastic can be utilized with creature oils, vegetable oils, and most oxidizing synthetic concoctions. Notwithstanding, it isn’t prescribed for use with oils, oil solvents, fragrant hydrocarbons, and in applications that request presentation to daylight or ozone.

These recorded materials are normally utilized elastomers for making O-rings, however different materials, for example, Kalrez, are likewise utilized in certain unique applications. Kalrez is a perfect swap for Viton in applications that have working temperatures of up to 500 degrees F. Also, there are different elastomers utilized for explicit fixing purposes. Whatever the material you decide for your application, care ought to be taken to guarantee its similarity with working temperatures, liquids, and condition. Viton O-rings

The criticality of picking the best material for your application is immediately clear when we consider the reason for Space Shuttle Challenger fiasco. This disaster was brought about by the disappointment of an O-ring that lost its flexibility and got fragile because of a startling drop in encompassing temperature. In spite of the fact that most O-ring disappointments probably won’t prompt the death toll at standard with this debacle, there is no denying the clear monetary misfortune brought about by a bombed machine or gadget.
