Abstract

A non-corrosive metallic sealing assembly (310) is disclosed having a super-elastic component (314) made of, e.g., nitinol. The super-elastic component can expand or contract to form a seal, preferably upon mechanical stress activation using interference fit with one or more other components (312, 320) of the assembly. The improved seal is useful in fluid connectors such as hoses, electrical connectors, torque transmission devices, in vibration-dampening devices, and hinge or ball and socket joints. The assembly can seal against other components having different coefficients of thermal expansion or contraction, offering reduced temperature sensitivity during seal formation and at high performance operating conditions.
