Spring Energized PTFE Lip Seals

Spring energized PTFE lip seals is a U-shaped Teflon seal with a special spring inside. The appropriate spring elasticity plus the system fluid pressure pushes out the sealing lip and gently presses the sealed metal surface to produce excellent sealing. Sealing effect. The braking effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, maintaining sealing performance. Widely used in seals for vacuum pumps, food industry, automobile industry, metering equipment, and other pressure vessels.
