Abstract: Systems and methods include providing a seal for an assembly. The seal includes a jacket having a base, an inner sealing leg, and an outer sealing leg, and further includes a spring disposed within the jacket between and in contact with the inner sealing leg and the outer sealing leg. The spring includes an annular support ring disposed within the spring. The support ring biases an outer diameter (OD) of the spring towards the outer sealing leg of the jacket to maintain contact pressure between the inner sealing leg of the jacket and the shaft of the assembly. The support ring controls thermal shrinkage of the spring and the outer sealing leg to maintain a seal between a housing and a shaft of the assembly when the assembly is operated at cryogenic temperatures.

Abstract: Systems and methods include providing an annular seal stack for an assembly. The seal stack assembly includes, at least one second annular seal, a spacer disposed axially adjacent to the at least one second annular seal, and a third annular seal disposed axially adjacent to the spacer. The seal stack assembly is disposed between a probe and a housing of the assembly and configured to provide an annular seal between the probe and the housing during operation of the assembly at cryogenic temperatures, during exposure of at least a portion of the seal stack assembly to cryogenic temperatures, during a change in pressure, during a change in temperature, or a combination thereof.
