Rotary Seals

Versatile Sealing for Demanding Environments

Greene Tweed designs customizable rotary seals for corrosive environments and wide temperature ranges. Rotary seals prevent leakage and keep equipment safe from dirt, mud, water, and contaminants.      

An unlimited number of custom-engineered configurations are available. Our design team works with you to find the right sealing solution no matter how demanding the application. Each order is manufactured specifically for your order, enabling easy retrofit and installation.
