Abstract

In the search for reliable, simple low-temperature static seals, O-rings made from elastomers have received little acclaim, since rubberlike materials are glassy at temperatures below 140°K, and no longer exhibit the properties ordinarily associated with O-ring seals. However, it has been demonstrated that with proper design the rubbery properties of the materials are necessary only during assembly of the seal[1]. During cool-down the sealing force is maintained at a safe level if the initial force is large enough.
