Spring Energized PTFE Lip Seal

● Spring energized PTFE lip seal introduction : It is a U-shaped Teflon seal with a special spring inside. It is composed of appropriate spring elastic force and system fluid pressure.
Push out the sealing lip and gently press the sealed metal surface to produce an excellent 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.
