Spring-energized seals typically consist of a polymer jacket and a metallic spring that provides a consistent load throughout the circumference of the seal and creates a leak-tight seal between the jacket and the hardware. The system pressure creates an additional sealing force between the jacket and the hardware. In this combination, the spring forces the seal lips against the gland and rod surfaces, while pressure assists the spring force.
