Will this o-ring hold up if I'm usin' it with some kinda hot oil? Gotta make sure it don't melt on me.

Question by: Glen M on Oct 30, 2025, 10:25 AM

With a temperature range of -25 to +300 degrees Fahrenheit, this o-ring is made from HNBR, which offers good resistance to heat and oils. Just be sure your application stays within that temperature range to ensure a good seal.

what's the temp range on this o-ring? got some equipment running in pretty harsh conditions and need to know if it'll hold up

Question by: Earl B on Dec 10, 2025, 12:15 PM

Rated from -25 up to +300 degrees Fahrenheit, so it covers a solid spread of operating conditions. Whether you're dealing with cold startup temps or sustained heat during heavy use, that range gives you a reasonable margin to work with in most industrial setups.
