Although HNBR O-rings are highly resistant to heat, oil and chemicals, there are some situations in which its qualities are limited. For example, they are not resistant to strong acids, ketones, ethers and chlorinated hydrocarbons which makes them of limited to no use in some chemical applications. Moreover, they are also less suitable at temperatures below 30°C, as the temperature is too low and then the material may lose its flexibility. When extreme chemicals or temperature resistance (above 150°C) is required, alternatives such as FKM (Viton®) or EPDM are recommended. Also, for use in the food or medical industry where specific certifications are required, HNBR O-rings are not always the best choice either. By carefully considering these restrictions, you will find the best seal for your application
Despite their excellent oil and chemical resistance, HNBR O-rings are not resistant to strong acids, ketones, esters and chlorinated hydrocarbons.
