The purpose of this report is to give the reader an appreciation of typical applications and problems encountered when sealing cryogenic and / or low temperature products. The term "cryogenics" can be defined as " the study of low temperatures or the production of the same".

Although cryogenics is often perceived by many to be limited to liquefied gases, it also encompasses low temperature hydrocarbons, refrigerants and coolants, to name a few. Therefore, this report will discuss all applications where the temperature falls below zero degrees Celsius (32 degrees Fahrenheit).
