Cantilever Spring Energized Piston Seal

Cantilever Spring Energized Piston Seals use a V-shaped spring inside a polymer jacket. During installation, the compressed V-spring provides sealing force to ensure a tight seal.

These seals replace rubber u-cups when they fail from chemical attack, extreme temperatures, friction, or wear. They're ideal for reciprocating applications like shocks, hydraulic cylinders, pumps,, and compressors.

The spring design concentrates load at the seal's front, making it suitable for environmental protection and scraping viscous materials. For FDA clean-in-place applications, the spring cavity can be filled with silicone.
