SES 200 Series
- Elliptical Coil Spring Energized Seals with Constant Lip Load
Elliptical Coil Spring Energized Seals (SES) are commonly used in rotary, reciprocating, and static applications, where constant lip load or constant friction for low-pressure applications is needed. The elliptical coil spring provides an almost constant load on seal lips independent of hardware tolerances, eccentricity, and seal wear.
The 200 Series incorporates a U-shaped seal jacket with a high performance, stainless steel elliptical coil spring with high spring loading, which provides excellent sealing at zero or low system pressure, even in the case of fluid and gas applications.
Seal jackets are made from high performance fluoroplastic compounds and engineered plastics that provide a low coefficient of friction, high abrasion resistance, dimensional stability, and outstanding resistance to most fluids, chemicals, and gases as well as a resistance to aging.
The 200 Series is available in six unique jacket materials to address a broad range of applications. Each seal jacket is used in combination with a high performance, stainless steel elliptical coil spring to apply positive sealing force to the mating surface.
