METAL 'E' RING SEALS

- E-Rings (E cross section seals, convolution seals) are engineered to operate in applications that require light loading, flexibility and high temperature capability. E-Rings operate primarily within the elastic limits of the material. The superior flexibility or springback characteristics are important when used in cavities that experience large amounts of separation during normal operation. - Applications include gas turbine engine housings, hot air ducting, exhaust manifold couplings and ball valve seat seals. This type of metallic seal exhibits very good fatigue resistance.
