Chemical listing guide for O-Rings
This is an alphabetical listing of most of the common chemicals we find in industry. The chart was made to be used with my technical paper, ” Selecting the correct elastomer for your application“.
You can learn several things from this listing:
- The preferred O-ring material for the application. Column #2
- If the fluid is soluble in water. Column #3
- If the fluid is hazardous. Column #4
Click any of the following headings to go to the right spot on the list:
Please remember that your chemical is often a mixture of several chemicals that can react with the O-ring differently than any of the single components of the mixture.
You should additionally be aware that is very common to clean and flush process lines with a solvent or steam. The O-ring you select must be chemically compatible with these cleaners and solvents.
The last thing to remember is that each O-ring has an upper and lower temperature limit. Do not exceed these numbers.
