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 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: An energizing element including: an energizing element body oriented about a central axis, the energizing element body defining an inner radius, IR, and an outer radius, OR, where the difference between the outer radius and the inner radius defines an adjusted width, W, of the energizing element body, where the inner radius and the outer radius determine an average radius, R, of the energizing element body about the central axis, where the energizing element body defines an aspect ratio, W/R, where W/R>0.1, where the energizing element body has a maximum linear contact length on the inner radius, LIR, where the energizing element body has a perimeter on the inner radius, PIR, and LIR/PIR>0.80, where the energizing element body has a maximum linear contact length on the outer radius, LOR, where the energizing element body has a perimeter on the outer radius, POR, and LOR/POR>0.55, and where the adjusted width is less than 5 mm.

Abstract: Systems and methods include providing a seal for a valve assembly. The seal includes a metallic annular body having a main body portion, a first sealing leg extending from the main body portion and that provides an axial seal with a component in the valve assembly, and a second sealing leg extending from the main body portion that provides a radial seal with another component of the valve assembly. The seal may also include a sealing ring assembly having a sealing ring support and a sealing ring that forms a radial seal in conjunction with the sealing bumps of the second sealing leg.
