Chemical Compatibility Guide

Chemical compatibility is a key factor in O-ring performance. Choosing the right material based on chemical compatibility and temperature exposure minimises costly failures that also could result in property damage and/or serious personal injury.

About the chemical compatibility guide

The information on this page was developed as a quick reference guide for O-ring chemical compatibility, with all information based on isolated material testing in optimal conditions at room temperature and pressure.

The O-ring chemical compatibility information’s is believed to be accurate and reliable. However, while every effort is made to ensure the accuracy of information contained on this page, M Seals can not warrant the accuracy or completeness of information.

Exposing rubber materials to multiple chemicals and compounding application factors like temperature pressure and gland design can result in significantly different performance.

Therefore, your specific application should not be undertaken without independent study and evaluation for suitability. For specific application recommendations, please contact us.
