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.
Answer by: Customer Support on Oct 31, 2025, 5:51 PM
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
Answer by: Customer Support on Dec 12, 2025, 11:28 AM
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.
