Spring Energizers for Critical Sealing Applications

Spring energizers apply continuous preload force to the sealing jacket, helping maintain sealing contact during pressure fluctuation, thermal expansion, wear, and dimensional tolerance variation.

Different spring structures provide different load characteristics for static and dynamic sealing applications.

Spring-energized seals use an internal spring energizer to maintain continuous sealing force under low pressure, temperature fluctuation, vacuum conditions, and dynamic motion environments.

Compared with conventional elastomer O-rings, spring-energized seals typically provide better chemical resistance, wider temperature capability, lower leakage risk, and improved long-term sealing reliability.

Cantilever V spring energizers and canted coil spring energizers are commonly used in dynamic sealing systems because they provide stable spring loading with relatively low friction characteristics.

The final spring selection depends on operating pressure, media compatibility, motion type, temperature range, and sealing structure.

Cryogenic sealing systems such as LNG, liquid nitrogen, and low-temperature transfer equipment typically require spring structures and materials with low-temperature resiliency.

Full contact springs, canted coil spring energizers, and selected helical spring configurations are commonly used in cryogenic sealing applications.

Cryogenic sealing systems typically require materials with stable low-temperature elasticity and corrosion resistance.

Common spring materials for cryogenic applications include Elgiloy®, Inconel® X-750, and selected stainless steel alloys depending on operating temperature and media conditions.

Yes. Spring energizers are typically customized according to sealing structure, media compatibility, temperature, pressure conditions, and motion type.

Custom cross-sections, materials, dimensions, and spring force requirements are available based on drawings, samples, or sealing application requirements.
