UPE Spring Energized Seal

Spring energized seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.

Product Details

What are UPE Spring Energized Seals?

UPE spring energized seals are seals that use a spring element to provide a tight seal between two mating surfaces. The spring element is generally made of a flat or round wire and is encapsulated by a high performance polymer that provides excellent chemical, temperature, and wear resistance. The UPE material used for the encapsulation of the spring element is characterized by its low coefficient of friction, high abrasion resistance, and chemical compatibility. UPE spring energized seals are available in various cross-sectional profiles and can be customized to meet the specific requirements of the application.

Benefits of UPE Spring Energized Seals

Low Friction Coefficient

Chemical Compatibility

High Abrasion Resistance

Flexibility - UPE spring energized seals are highly versatile and can be designed for various applications, from high-speed rotary seals to low-pressure static seals.

Limitations of UPE Spring Energized Seals

While UPE spring energized seals offer several benefits, they also have certain limitations. UPE is not suitable for use in high-temperature applications above 100°C as it can deform at these temperatures. Additionally, UPE has poor UV resistance, which means that it can degrade when exposed to sunlight for extended periods.
