Spring energized seals are lip seals that incorporate a metal or composite spring into the seal design. The spring energizes the seal lip against the mating hardware, creating a seal capable of compensating for movement in a dynamic application. They are used in single acting dynamic applications and should be oriented with the spring towards the pressure side.

Spring energized seals are primarily used in extreme environments where a standard moulded elastomers or thermoplastics cannot meet the application requirements due to the material limitations. As these seals are designed to meet varying applications and high-performance requirements, Hi-Tech Seals mainly stocks custom design seals.
