Question by: Todd M on Dec 13, 2025, 9:33 AM
how hot can these run before they give out? we got a pump that gets pretty warm.
Answer by: Customer Support on Dec 15, 2025, 7:18 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.

For a -06 Bump Tube O-Ring Seal fitting, this matches the -06 dash size and is made specifically for that ORS fitting style. The dimensions are 0.301 inch ID, 0.426 inch OD, and 0.0625 inch width, with HNBR material at 70 durometer.
Question by: Eddie Y on Mar 14, 2026, 8:56 AM
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
Answer by: Customer Support on Mar 16, 2026, 7:50 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.
Question by: Kirk G on Aug 6, 2025, 12:12 PM
Will this little guy hold up to hydraulic fluid without dissolving?
Answer by: Customer Support on Aug 7, 2025, 8:49 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.
