|Specify Parts of Viton
® know the
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.
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 type 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.
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
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.
