how hot can these run before they give out? we got a pump that gets pretty warm.

Question by: Todd M on Dec 13, 2025, 9:33 AM

You can safely run these O-rings in applications reaching up to 300 degrees Fahrenheit. They also hold up well on the freezing end all the way down to -25 degrees.

what temp range does this o-ring hold up to? got some lines that see pretty wide swings and need something that wont give out on me

Question by: Eddie Y on Mar 14, 2026, 8:56 AM

HNBR material at 70 durometer handles a range of -25 to +300 degrees Fahrenheit, so moderate cold and fairly high heat are both within spec. That makes it a solid choice for systems that cycle through varying conditions without a lot of babying.

Will this little guy hold up to hydraulic fluid without dissolving?

Question by: Kirk G on Aug 6, 2025, 12:12 PM

HNBR is what this O-ring's made of, and it's known to stand up pretty well to hydraulic fluids, plus it can take temps from -25 up to 300 degrees.
