OD2.5x1x0.1mm Helical H type O type spring 1.4310

Description Of Spring Seal/ spring energized seal/ Variseal

Spring Seal/ spring energized seal/ Variseal is a high-performance sealing element with special spring inside U-shaped Teflon. With proper spring force and system fluid pressure, it pushes out the sealing lip (face) and gently presses the sealed metal face to generate excellent sealing effect. The actuating effect of the spring can overcome the slight eccentricity of the metal mating surface and the wear of the sealing lip, and the expected sealing performance can be maintained.

Spring energized seals are designed to be used in a wide range of applications and provide improved sealing performance where conventional seals may fail such as high/low speeds, wide temperature ranges and/or contact with corrosive media

SPRING SELECTION

When considering a spring energized seal, the spring choice can be very important. Through the spring the seal can be “fine tuned” for each individual application. For example, if an application requires tight sealing of light gases in a static environment then the helical spring may be a good choice. Likewise, if an application requires constant force over the useable life of the seal in a dynamic environment then perhaps the spiral pitch spring is the right choice. Once the spring type is selected, in some cases there is additional variability with the spring load.
