Spring energized piston seals feature a polymer sealing jacket and an internal spring that applies continuous pressure to maintain contact with the cylinder bore. This ensures tight, low-friction sealing in dynamic conditions. Commonly made from PTFE, PEEK, or other high-performance materials, spring energized piston seals resist wear, chemicals, and extreme temperatures. They are used in aerospace systems, cryogenic equipment, chemical processing, and high-pressure hydraulic cylinders, delivering long-term sealing reliability in demanding environments.
