With more than 30 years developing and researching on seal industry, we can also produce spring energized PTFE seals. The PTFE spring energized rod sea is a kind of high-performance seal with special spring in U-shaped Teflon. The sealing lip (surface) is pushed out by the appropriate spring force and the system fluid pressure to gently press the metal surface to produce 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, and maintain the expected sealing performance. can be used as static seal, dynamic seal and slow dynamic seal. They have very excellent chemical compatibility .
