How It Works
The internal spring continuously applies force to the sealing lip, maintaining tight contact with the mating surface. This compensates for wear, pressure fluctuations, thermal expansion, and low-pressure or vacuum conditions, delivering reliable sealing performance throughout the service life.
Key Features

Advantages Over Conventional Seals
Spring Energised Seals outperform O-rings and lip seals in applications involving extreme conditions. They provide superior sealing reliability where elastomers may harden, swell, or fail.
Customization
Spring Energised Seals can be customized in terms of material, spring design, dimensions, and profiles to meet specific operating conditions and industry standards
