Material expertise

Manufactured in many shapes and sizes, seals are critical components that are found in all major industrial applications and related equipment. By performing a range of functions, such as energy and shock absorption, media separation, pressure containment, and wiping and scraping, seals ensure applications operate properly through correct material selection and design.

With an extensive history of product innovation and material development, our team understands how critical material selection is to sealing performance.

Selecting the right material

The right combination of materials is a critical factor that can mean the difference between success and failure when a seal is installed in a given application.

Our engineers and material scientists can also work with you to determine the best material to use for your application.


Our full range of sealing products and components is complemented by sustained technical support offered in the areas of material selection and development, as well as custom compounding that can be tailored to meet your specific needs.

Our team of engineering experts and specialists regularly evaluate material compatibility and performance scenarios to offer the optimal sealing solution.

As part of this knowledge base, our in-house material library contains current and historical data on custom blends and formulations that document distinctive performance characteristics for the full range of sealing products we offer worldwide.
