Helical Spring Energized Seals

MFP Seals Helical spring loaded seals are made from a flat ribbon and wound into a round cross section helix geometry. The Helical spring is designed for use in U-Cup style seals, as well as other configurations, for radial or axial compression energized seals and produces a very high unit load over a small deflection range. The Helical spring loaded seal is usually used in static or slow dynamic applications and often for extremely low temperatures.
