SUCCESS HISTORIES : Extreme low temperatures make most
O-rings brittle which in turns leads to failure. The TEO Cryogenic
seal was created by an Aerospace Engineer Bill Creavey in 1964 to
combat the harsh environments associated with liquid oxygen and the
problems involved with sealing in other cold media such as liquid
nitrogen and hydrogen. Since then the seals have been successfully
used in several shuttle /rocket launches and a multitude of other
applications by organizations such as Boeing, NASA, Lockheed, and
newly founded SpaceX.
