Spring energized seal is a spring-actuated, pressure-assisted sealing device consisting of a PTFE (or other polymer) jacket, especially encapsulating a corrosion-resistant metal spring energizer.
The jackets are precision machined from PTFE, filled PTFE composites and other high-performance polymers with temperature range from cryogenic to 280°C. We have a variety of energy storage springs for choose,each with characteristics that meet specific requirements.

spring energized seals are precision machined parts, both the seal diameter as well as the seal section are function critical. The jacket allows the system pressure to assist in maintaining a certain seating load. The high precision metal spring, located in the jacket creates the initial seating load needed to create positive sealing. Hongda are available in a wide variety of designs, each with a spring designs optimized to handle the most demanding applications.
