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

Question by: Billy W on Nov 7, 2025, 9:26 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.

trying to match up an old ORFS o-ring, are these the right dimensions for a 1/4 inch tube size?
