Compound Compatibility Table
Do you know how O-rings will behave when in contact with different materials? Understanding the chemical compatibility of materials is key to ensuring the tightness and durability of any sealing system.
In this section, we offer you a practical tool to identify which materials are most suitable depending on the fluid, temperature, and working conditions of your application. Whether it's for O-rings, oil seals, or other sealing elements, this guide will help you make safer and more efficient decisions.
1 – Very good suitability.
2 – Good suitaibility.
3 – Limited suitability.
4 – The elastomer is not suitable for the application.
x – Insufficient information available for service in this media.
