O-Ring Colors

Over time and in certain industries, specific o-ring colors have been used to easily, visually identify what type of o-ring is being used.

The chart below shows the standard colors that Global O-Ring stocks in our most common materials/compounds. Please note that we can supply ANY O-RING IN ANY COLOR.

**Disclaimer: It is never safe to assume an o-ring is a certain type, material, or hardness just based on the color alone.**
