Abstract: Flexible seal assemblies having a relatively low torsional rigidity and high longitudinal flexure to thereby allow the flexible seal assembly to flex between adjacent components and maintain a seal, even when movement between adjacent components occurs, is described. In some embodiments, the flexible seal assembly includes one or more layers of metal matrix material, the metal matrix material being comprised of a plurality of short segments of thin wire arranged randomly and sintered together to form a semi-rigid sheet. The one or more layers of metal matrix material can be sandwiched between an upper casing and a lower casing of a metal alloy casing. In various embodiments, additional features are provided for helping to make sure the seal assembly stays together, such as spot welds formed through the seal assembly, an S-shaped casing, and a recess/protrusion feature provided on adjacent layers of metal matrix material.

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.
