Spring Energized PTW Seal

The Spring Energized PTW Seal works by a spring-loaded seal that consists of a polymeric seal and a corrosion-resistant stainless steel spring. The sealing ring is installed in the groove, the spring is pressed to form an outward tension, and the sealing lip is pressed against the sealing groove. Since the spring permanently provides the elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the fitting part, thereby forming Sealing from vacuum to low pressure....
