Frequently Asked Questions

What is an energized seal?

An energized seal is a sealing element that uses a secondary component—such as a metal spring, elastomeric insert, or back-up ring—to apply a continuous, pre-loaded force against the sealing lips. This energization maintains consistent sealing contact across varying pressures, temperatures, and wear conditions, making energized seals ideal for high-pressure hydraulic and dynamic applications.
