What is spring energized seals

Variseal is called a spring energized seal. It is a type of sealing ring with a special spring built in a U-shaped sealing ring, or a high-performance seal with a special spring built in a U-shaped PTFE ring. With proper spring force and system fluid pressure, the sealing lip (surface) is pushed out and gently pressed against the sealed metal surface to produce a very excellent sealing effect. The actuation effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, continue to maintain the expected sealing performance.
