A seal includes a first portion and a second portion, wherein the seal is configurable as a continuous seal having an overlapping region in which the first portion and the second portion overlap. The seal has a jigsaw seal configuration at the overlapping portion. The seal includes a transverse surface that extends between the inner surface and the outer surface of the seal, and a first sealing bead located at a junction between the transverse surface and the inner surface and a second sealing bead located at a junction between the transverse surface and the outer surface. The transverse surface may be recessed relative to the first and second sealing beads when the seal is in a non-compressed state. When the seal is in a compressed state, in the overlapping region one of the first or second sealing beads at the first portion and the other of the first or second sealing beads at the second portion seal against each other, and the transverse surface contacts and seals against a surface of a component being sealed.

Extruded interlocking jigsaw seal with sealing beads

A radially expandable backup ring (50) with relatively rigid segments () and relatively resilient segments () that are integral with one another to circumferentially urge the relatively rigid segments () together when the backup ring () expands. The backup ring () may radially expand to reduce or eliminate a radial gap between the backup ring () and a radially inwardly facing surface of a corresponding cased wellbore () to prevent or minimize axial extrusion of a corresponding sealing member (), such as a compressible packer seal of a cased-hole retrievable packer assembly. The relatively resilient segments () allow the backup ring () to elastically expand and retract to prevent axial extrusion of the sealing member (). The relatively rigid support segments () may be axially aligned with a corresponding relatively resilient segment () of the backup ring to prevent axial extrusion of the sealing member () through the corresponding relatively resilient segment ().

Expandable backup ring

A hollow seal for use in sealing between relatively movable first and second panels, such as between a fixed window panel and a slidable window panel of a rear window of a pick-up truck or the like. The hollow seal has an internal geometry that supports an outside layer or portion of the seal under pressurization to prevent leakage and seal blowout. The outside portion is shaped to provide a pair of laterally spaced-apart sealing lips that have a pressure-activated sealing geometry for tight sealing against the panels when under pressurization.

Supported hollow seal

A ring seal includes a sealing ring including an asymmetric body portion having axially-opposed and radially-offset seal beads. The ring seal may also include a reinforcement ring carried at least partially in the sealing ring to distribute load across the seal beads. The ring seal may further include a skirt depending generally axially from the body portion and defining an inner diameter of the sealing ring and preferably having frusto-conical cross-sectional shape.
