Nitrile vs Viton – What is the Difference?

Nitrile vs Viton – What is the Difference?

Nitrile is a compound that is organic with a chemical formula which is general as R-CN. Viton is just a name used to refer to fluoropolymer elastomers and synthetic rubber. Nitrile and Viton are approved elastomers which are mostly used. Nitrile is commonly referred to as NBR, while Viton is referred to as Fluorocarbon rubber. Both Viton and NBR have mostly used in industries because they have great compression resistance and other excellent properties. Nitrile and Viton have different properties, characteristics, and kinds of applications. Therefore, if you want to use either Viton or NBR, below is some crucial information to consider.                         

Viton vs NBR O-Rings Kits

Viton and NBR O-Rings Kits are kits that provide a solution that is used in seal replacement. There are various options to offer this solution for various sealing needs like environmental exposure, chemical resistance, and different temperature range. You must consider consulting well with the O Ring kits suppliers before you buy one. 

Viton and NBR O-Rings Kits options are splicing, metric, and parker O-rings kits. Viton O Ring KITS are good at giving excellent chemical resistance to weather, acid, heat, ozone, oil, and flame. NBR O-Rings Kits are good at providing chemical resistance to oil, diluted acids, alkaline, and fuel.

The differences between Nitrile and Viton

The appearance

Nitrile is yellow, while Viton is green-brown.


Nitrile compounds consist of carbon as the main component and hydrogen, which is a butadiene monomer. Viton compound consists of carbon as the main component and fluorine and hydrogen, which is flour elastomer.

Operating temperature

NBR O-Rings Kits are most effective in a given range of a lower temperature of -30°C and a higher temperature of 100°C. In comparison, Viton O Ring KITS can be more effective between lower temperatures of -20°C to a temperature of 210°C. You can check them on O Ring kits suppliers like Polymax.


Nitrile is most suitable for offering resistance to the general application, petroleum oils, aliphatic hydrocarbon, hydraulic fluids, and water. At the same time, Viton is most suitable for applications that need high chemical and temperature resistance. These include acids, oils, gases, silicon fluids, aromatic gases, and halogenated hydrocarbons. 


Nitrile is a product that, when applied, works best with chemical and temperature resistance. Viton works best when applied to chemical processing appliances and automotive.

Cost of Nitrile vs. Viton

Nitrile is cost-effective as compared to Viton compound. Approximately Viton is 15 times more expensive than Nitride. Despite their different prices, Viton and NBR O-Rings Kits are stocked from the same O Ring kits suppliers.

Environmental Properties

Viton O Ring KITS have a very vast chemical range of resistance. Viton and its kits can resist environmental effects like mould, UV exposure, oxidation, ozone, and fungus. Viton is specifically designed to resist oils or lubricants-based products. Nitride is less superior to Viton in terms of weather ability, but it is best at tear and abrasion resistance in heavy-duty applications in industries.

Therefore, the crucial distinction between Viton and NBR is the material functions and temperature range. Also, Viton has a high density as compared to NBR. When you want to select either Nitrile or Viton, then consider the points above how different they are. It is essential to look for reputable suppliers when dealing with O ring kits and also Viton kits.
