Welcome to our Viton® Specifications Section

Here you will find our Viton® specifications chart which can also be downloaded in PDF. The Viton® properties that are listed below are for our most popular Viton® 75 durometer (75A) rubber material. Make sure you review all of our other popular materials to ensure that the material you choose is correct for your application. If you need properties that are slightly different than the ones listed below, we can compound the formulation of the rubber material so that the Viton® rubber specifications suit your needs. Finding the correct material is important as the seal can degrade easily if the material is not compatible with the environment.

Viton FKM is DuPont-Dow Elastomer’s trade name for fluorocarbon elastomers. Fluorocarbon elastomers exhibit excellent resistance to high temperature and low compression set. They respond very well with resistance to ozone, high temperatures, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals over a temperature range of -25°F to +400°F. Low temperature resistance for static applications is limited to approximately –40°F (–40°C) under special formulation. Under dynamic conditions, the lowest service temperature is between 5°F and 0°F (–15°C and –18°C). Gas permeability is very low and similar to that of butyl rubber. Special formulation can also improve resistance to water, steam, acids and fuels.
