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.
