what temp range does this o-ring hold up to? got some equipment runnin pretty hot and need to know if it'll handle it
Answer by: Customer Support on Jul 25, 2025, 7:07 PM
Buna-N at 90 durometer gives you a working range of negative 40 up to positive 250 degrees Fahrenheit. That covers most heavy-duty hydraulic setups without issue. If your system stays under that ceiling, you're in good shape with this one.
