Spring Energized Seals
PTFE spring-energized seals are designed for the most demanding applications, offering exceptional sealing performance in extreme temperatures, high-pressure environments, and chemically aggressive conditions. These seals provide both static and dynamic sealing, ensuring reliability across various industries.
As system pressure increases, it enhances the seal’s effectiveness by engaging the shaft or bore. The internal spring maintains resilience, compensating for jacket wear, hardware misalignment, and eccentricity to deliver long-lasting performance. Choosing the right jacket material is essential to optimizing seal efficiency and durability.
Material Options:
- Virgin PTFE
- Graphite PTFE
- Moly-Filled PTFE
