To help you better gauge the usefulness of a seal material in a given fluid environment, we offer this Chemical Compatibility Guide (see Table 3). It features the most common fluids that your shaft seals will be likely to encounter in service.

This guide is based on volume swell, and though excessive swell is perhaps the most obvious sign of incompatibility, it is not the sole indicator. Changes in physical properties such as hardness and tensile strength are common. Length of exposure and ambient temperature will also undoubtedly affect a material’s response to a chemical.
