Cantilever (V) Springs for Energized Seals
Cantilever V Springs (also called V Springs or Meander Springs) are metal energizing elements used in spring-energized seals. The V-shaped cantilever geometry provides a stable, near-linear load over a wide deflection range, ensuring consistent sealing force.
They are typically installed inside U-cup or PTFE seals as radial or axial energizers, compensating for wear, pressure variation, and thermal expansion. Suitable for both static and low-speed dynamic applications.
