Seal Science, Inc. PolySpring™ - Spring-Energized Seals 842 AH Series

Spring energized seals are uni-directional u-cups seals. An energizer is required to provide a pre-load for low pressure sealing and to maintain intimate lip contact with the mating hardware. As the seal wears the spring continues to exert pressure on the lip until the useful performance of the seal is exhausted. The seal is designed to have the pressure entering the “U”. Seals can be used from high vacuum to over 100,000 psi (combined with the appropriately designed back-up ring).
