Abstract: A metal O-ring is provided. The metal O-ring has a sidewall with an outer surface and an inner surface. The outer surface of the sidewall is machined to selectively thinning the thickness of the sidewall, such that the sidewall of the of the metal O-ring has a plurality of thicknesses equal to or less than a maximum thickness and equal to or more than a minimum thickness. Selectively thinning the sidewall by machining the outer surface allows for control of the elasticity of the metal O-ring. Controlling the elasticity of the metal O-ring, and potentially increasing the spring back, may provide for increased contract pressure at a sealing interface, which would facilitate sealing. The machined outer surface of the metal O-ring are generally machined to flat surfaces.

Abstract: An annular seal comprising a metallic ring having a cross section. The cross section includes an axially extending body portion having a radial width and an axial height. A spaced apart pair of sealing arms extend axially from the body portion, wherein each sealing arm includes a radially opposed arcuate sealing surface. The arcuate sealing surface may be convex, for example. The spaced apart pair of sealing arms are spaced apart a radial distance greater than the radial width of the body portion. A sealing system comprises a plurality of interconnected metallic rings wherein the body portion engages the sealing arms of an adjacent metallic ring.

Abstract: A resilient metal seal that includes a PTFE jacket or liner capable of improving the sealing performance of the resilient metal seal and providing a near chemically inert surface to protect the seal from coming into contact with potentially damaging media is provided. In some embodiments, the resilient metal seal is an E-, U-, C-, or V-shaped resilient metal seal. A jacket made of PTFE or similar material can be included on the interior or exterior surface of the resilient metal seal. The jacket can include a locking feature to prevent against the jacket becoming dislodged from the resilient metal seal.
Abstract translation: 提供了一种弹性金属密封件，其包括能够改善弹性金属密封件的密封性能并提供近化学惰性表面以保护密封件不会与潜在的有害介质接触的PTFE护套或内衬。 在一些实施例中，弹性金属密封件是E-，U-，C-或V形弹性金属密封件。 由PTFE或类似材料制成的外套可以包括在弹性金属密封件的内表面或外表面上。 护套可以包括锁定特征，以防止护套从弹性金属密封件移开。
