The chemical compatibility of rubber is extremely important as the rubber can degrade rapidly if the rubber material is not compatible with the environment or media that it comes into contact with.
As the nbr content increases resistance to petroleum base oils and hydrocarbon fuels increases but low temperature flexibility decreases.
O ring chemical compatibility chart learn how different o ring materials and chemicals interact.

Use this rubber chemical resistance chart to make sure that the elastomer or o ring seal you choose will be compatible with the particular environment.
About nbr due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of 35 c to 120 c 30 f to 250 f nitrile nbr is the most.
Resistance data was taken from parker s 2008 edition of the parker o ring handbook.

This material has a desirable set of properties including low compression set high resistance to abrasion and good tensile strength.
Buna n o rings also referred to as nbr o rings and nitrile o rings are the most widely used o ring material in the word because of low cost good mechanical performance with resistance to water most basic oils lubricants and some fuels many pneumatic hydraulic systems and the default choice for basic applications.
Also called nbr or buna n nitrile o rings are probably the most economical and widely used elastomer out there.
