Lee Specialities Ltd. of Red Deer, Alberta, Canada was fined $90,000 for trying to export Viton O-rings to an Iranian address in January 2012, in violation of the Special Economic Measures Act.  The Act is intended to prevent nuclear weapon-related material from entering Iran.  The O-rings, made from a special heat-resistant synthetic rubber, are often used in oilfield parts but can also be used in nuclear reactors.  The order was placed by Kan Dana Middle East LLC, which has affiliates in Iran and Dubai.  Canada Border Services Agency seized the shipment during a routine inspection at Calgary International Airport.
