NASA NTRS1966

Bimetallic devices help maintain constant sealing forces down to cryogenic temperatures

Tantalum washers compensate for different thermal coefficients of expansion between stainless steel and an aluminum O-ring. The washers have sufficient thickness to maintain a vacuum seal from room to cryogenic temperatures.
