what temp range does this o-ring hold up to? got some equipment running pretty hot and need to know if it'll handle it

Answer by: Customer Support on Nov 9, 2025, 5:51 PM

Rated from -40 up to +250 degrees Fahrenheit, so it covers a solid spread on both ends. Cold startup conditions and higher operating temps are both within range for this one.
