Q & A — Why do rings fail?

Q: Isn't premature ring failure the result of rings not seating because they are defective in the first place?

A: No, that's rarely the case. Still, this question comes up frequently in the industry, not just at Deves. It deserves a detailed answer. In the article "When Rings Fail," we've put together a Deves staff report that should give you a better idea of why some rings still do the job past 100,000 miles and others fail early on.
