Product Details

The sealing ring is installed in the groove, and the spring is compressed to form an outward tension, which promotes the sealing lip to close to the sealing groove. Because the spring permanently provides elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the mating parts. Sealing from vacuum to low pressure range. In addition, the system pressure will assist the spring to accumulate energy. The greater the pressure, the more fully the sealing lip fits the groove, thereby forming a high-pressure seal.

There are many types of metal springs to choose from, including O-shaped springs, V-shaped springs, and U-shaped springs to meet the sealing requirements of different forms of motion. In some occasions, O-rings of different materials can be used as elastic bodies instead of metal springs.

The sealing shell is made of PTFE, filled PTFE, PEEK, filled PEEK, PVDF, PPS or other high-performance polymer materials through mechanical processing. The material determines that the spring energy storage sealing ring is suitable for the temperature range from -268°C to +427°C Inside, almost all liquids, chemicals and gases are sealed. And can be stored indefinitely, there is no aging problem.
