Dear Engineer,
We have recently observed premature failure of the ozone diffuser gaskets. These gaskets are stocked and used accordingly. Operating temperature is around 70 F.
Historically, they have lasted around 3–5 years in service but we have started seeing failures after just 1 year. The material is becoming gummy and is no longer sealing properly.
The Viton used was grade "A".
Can you tell if grade A Viton is chemically compatible for this application? What other factors can be involved that can give this kind of failure?
