Abstract: Systems and methods include providing an annular seal stack for an assembly. The seal stack is disposed within an annulus formed between a probe and a housing of the assembly and configured to provide a radial seal between the probe and the housing. The seal stack includes a first support retainer, a first lipseal, a first seal support system comprising at least one support ring disposed between the first support retainer and the first lipseal, a second support retainer configured to support the first lipseal, a second lipseal, a second seal support system comprising at least one support ring disposed between the second support retainer and the second lipseal, and a third support retainer configured to support the second lipseal.

Abstract: Systems and methods include providing an annular bimetallic seal for an assembly. The bimetallic seal includes a first sealing component formed from a first material, a second sealing component formed from a second material that is different than the first material, and a joint formed between the first sealing component and the second sealing component. The bimetallic seal is configured to form a radial seal between a first assembly component and a second assembly component formed from dissimilar metallic materials. The coefficient of thermal expansion (CTE) of the first material and the second material are configured maintain the radial seal at extreme operating temperatures between the dissimilar metallic materials of the components of the assembly.

Abstract: Systems and methods include providing an annular seal for an assembly. The seal includes a metallic annular body comprising an inner sealing leg having a first sealing lip, a second sealing lip, and a valley disposed between the first sealing lip and the second sealing lip. The valley contains a plating reserve, such that the plating thickness in the valley is greater than the plating thickness on the first sealing lip and the second sealing lip.

Abstract: The present invention is directed to a high-pressure bi-directional sealing system having circumferentially extending outer support rings (1520, 1900), annular, axial seals (1600, 1800) between the outer support rings (1520, 1900) and a circumferentially extending inner support ring (1700) located between the annular, axial seals (1600, 1800). The outer support rings (1520, 1900), seals (1600, 1800), and circumferentially extending inner support ring (1700) are located within a space between an outer tube (1502) and an inner tube (1504) that is telescopically disposed within the outer tube (1502). Seals (1600) and (1800) are oriented in opposite directions. Specifically, the opening of seal (1600) is facing in a first direction and the opening of seal (1800) is facing in a second direction that is opposite the first direction. This configuration enables the high-pressure bi-directional sealing system to handle pressure in both directions.
