What are Freudenberg O-rings?

Freudenberg is an industry-leading brand that specializes in the design and manufacture of unique products - from sealing packages to bellows to dust caps to O-rings. 

Freudenberg specializes in creating different types of O-rings, such as those in standard sizes for common parts and applications and custom sizes for more unique parts and components.

There are two main types of O-rings: static and dynamic. Static O-rings are designed to come into contact with two or more surfaces that don't move, while dynamic O-rings are designed to form a seal between surfaces that do move. Freudenberg makes both static and dynamic O-rings, which means you can get an O-ring sealing solution for virtually any application. 

When you work with Wyatt Seal, we'll ensure you get the right O-ring for the job so that it performs well for your application.
