Spring-energized lip seal
Coorstek
Energized PTFE seals offer extreme-temperature, high-pressure, chemically inert, static and dynamic seals for the most demanding applications. Our thin, flexible PTFE sealing jacket, made resilient by an internal energizing spring, applies a load to the sealing element at low pressures. As the system pressure increases, the spring engages to create a highly efficient seal against the mating surface. The spring provides permanant resilience to the seal jacket and compensates for jacket wear, hardware misalignment or eccentricity.
