Buna o rings temperature rating. O ring material family chemical compatibility temperature resistance and other properties all factor in to o ring material selection for an application. Also notice that silicone has high rubber temperature resistance and also great low rubber temperature resistance. These buna n o rings are made of fda listed material for use with food and beverage. However before you choose silicone for an o ring seal due to it s o ring temperature range there are also other silicone shortcomings so make sure that it can withstand your particular environment by going to our rubber properties section and rubber chemical resistance chart.

Depending on the grade the working temperature range is considered to be 26 c to 205 230 c 15 f to 400 440 f. O ring material quick reference guide rubber sealing materials. Find o ring temperature ranges in the attached o rings temperature guide for o ring compounds and general elastomers including viton fluorosilicone nitrile silicone epdm kalrez neoprene and aflas materials. But for short working periods it will take even higher temperatures.

Viton seals hold indefinitely at temperatures up to 400 f and can last up to 48 hours at temperatures up to 600 f. Viton is the choice over buna for high temperature applications. While both viton and buna seals both serve as great sealing options at moderate temperatures viton is far superior to buna for high temperature applications.
