There are different types of Viton. A good example of the differences can be viewed by examining the following chart: Viton A is the most common grade while the chemical compatibility and cost increase as you go accross the chart.

While there are substitues that will often perform, specifying the most recognized name in FKM material is an inexpensive form of insurance. Insurance that you will get what you pay for. Not all FKM's are equivalent.

Specify the Grade you need:

Specifications that are insufficient, inaccurate or that allow substitutions open the door to quality and performance problems. When you specify DuPont Performance Elastomers' Viton®, the most specified fluoroelastomer worldwide, you can enhance your products' performance by ordering the specific grade of Viton® that has been tailored for your application needs.

Viton® was introduced in 1958 and scientists and engineers have relied on DuPont and now DuPont Performance Elastomers Viton® for its superior performance and unique properties ever since. However, DuPont Performance Elastomers is not the only company that manufactures FKM products. Many people in the industry incorrectly refer to any and all FKM elastomers as Viton®. As a result, you could end up with sealing products that are not the type of Viton® you need, let alone made of 100% virgin DuPont Performance Elastomers Viton®. Products not made from DuPont Performance Elastomers Viton® may fall short of the expected performance levels afforded by the stringent quality standards DuPont Performance Elastomers has set for Viton®, which is manufactured at ISO 9002 registered facilities worldwide.

Q. What is FKM?

A. FKM is the ASTM designation for the fluoroelastomer category. It is not a mark of quality. Not all FKMs are equivalent, and some may fall short on desired performance.

Q. What does the "Made With Genuine Viton®" seal mean?

A. It means the part has been manufactured and distributed in accordance with DuPont Performance Elastomers' guidelines. Only parts made with 100% virgin Viton® as the sole elastomeric component are labeled with this seal.

To ensure that you always receive the highest quality FKM products available, insist on 100% virgin DuPont Performance Elastomers Viton® and look for the "Made With Genuine Viton®" seal.
