Ozone Compatible Materials

22nd Apr 2020

Many of these materials were tested in-house at Ozone Solutions. Some are commonly known and rated as shown by others. All tests were performed at very high levels of ozone concentration. For any materials not shown, please call. We may have data on file or we can use our labs to test the material for you!

Our Rating System

  Rating Description
A Excellent Ozone has **no effect** on these materials. They will last indefinitely.
B Good Ozone has minor effect on these materials. Prolonged use with high concentrations of ozone will break down or corrode these materials beyond usefulness.
C Fair Ozone will break down these materials within weeks of use. Prolonged use with any ozone concentration will break down or corrode these materials beyond usefulness.
D Poor Ozone will break down these materials within days or even hours of use. These materials are not recommended for any use with ozone.
