Rubber O-Ring Chemical Compatibility Chart - O-Ring Material Resistance Guide

Basic O-Ring chemical resistance compatibility information is based on isolated generic O-Ring material testing in optimal conditions at room temperature and pressure. Exposing rubber O-Ring materials to multiple chemicals and compounding application factors like temperature pressure and gland design can result in significantly different performance. Specific material compound formulations can significantly alter generalized performance ratings. Please contact an application engineer for assistance in selecting the compound that provides the best combination of performance and price for your specific application.

Generalized O-Ring compatibility information is believed to be accurate and reliable. However, Marco Rubber makes no warranty, expressed or implied of actual performance in specific applications. It's the user's responsibility to evaluate specific parts prior to use.
