An assembly (500) is provided including: a first component (10) having a first outer surface (15) defining an opening therein; a second component (30) having second surface (60); and a sealing system (100). The sealing system includes a sealing member (200) and a support member (300). The sealing member is configured for providing sealing between the first component and the second component with respect to the opening and along a generally non-planar sealing perimeters. The support member is configured for supporting the sealing member in a generally non-planar configuration corresponding to the generally non-planar sealing perimeter. At least one of the second component and the support member is configured for enabling the sealing system to be mounted to the second component in a sealing position wherein to align the sealing member with the second component along the sealing perimeter. The support member is configured for being sealingly affixed to the first component subsequent to the system being mounted to the second component in the sealing position.

A gasket for placement between a base of an aircraft structure and the underside of a workpiece, such as an aircraft antenna, is disclosed. The gasket has a cured polyurethane elastomeric gel body with a multiplicity of holes therethrough. The body typically has a flat lower surface and upstanding side walls, but the top surface is non-flat. The top surface may have sloped areas or raised tabular areas or a combination. The gel body may also have a skeleton member, such as a flexible metallic screen or other woven member. When the gasket is placed between the aircraft base and the workpiece, threaded on fasteners, and the fasteners torqued down, the non-flat upper surface will flow such that, at proper torque setting, it fully coats and fully covers the underside of the workpiece and, typically, makes contact with the screen or skeleton member, which also makes contact with the upper surface of the base.

A sealant is provided for use on an aircraft or other vehicle. The sealant may be used with a gasket. The sealant is a perimeter seal that comprises a polyurea member. The polyurea member is a self-curing, two-component mix. It may cure to a hardness in the range of about 40 to 100 (Shore A). It may maintain an adequate peel strength to withstand multiple thermal and pressure cycling, and may have a working life, wherein it may be shaped, of less than about eleven minutes.

A spherical annular seal member 38 is used in an exhaust pipe joint and includes a spherical annular base member 36 defined by a cylindrical inner surface 32, a partially convex spherical surface 33, large- and small-diameter side annular end faces 34 and 35 of the partially convex spherical surface 33, and an outer layer 37 formed integrally on the partially convex spherical surface 33 of the spherical annular base member 36. The spherical annular base member 36 includes a reinforcing member made from a metal wire net 5 and a heat-resistant material containing expanded graphite filling meshes of the metal wire net 5 of this reinforcing member and compressed in such a manner as to be formed integrally with this reinforcing member in mixed form. In the outer layer 37, the reinforcing member, the heat-resistant material, and the solid lubricant are integrated in mixed form.

A sealing device includes a reinforcing ring and an elastic body part formed from an elastic body and attached to the reinforcing ring. The elastic body part includes a seal lip projecting toward one side in a direction of an axis, a secondary lip portion projecting toward another side in the direction of the axis, and an outer peripheral portion covering the reinforcing ring from an outer periphery side. The seal lip projects beyond the reinforcing ring toward the one side, and the secondary lip portion projects beyond the reinforcing ring toward the other side. In the outer peripheral portion, at least one identification part acting as a mark is formed further on the one side or the other side than a middle of the outer peripheral portion.

A gasket includes an annular reinforcing ring formed around an axis, an annular base that is formed around the axis and that is formed from an elastic body into which the reinforcing ring is embedded, and an annular seal lip formed around the axis. The annular seal lip is disposed on an inner periphery side of the base and is integrated with the base. The seal lip includes one lip portion extending to the inner periphery side as progress toward one side in a direction of the axis and another seal lip portion extending to the inner periphery side as progress toward another side in the axis direction. A sum of a width of the base in a radial direction and a width of the seal lip in the radial direction is greater than a thickness of the base in the axis direction.

Gaskets for sealing two mating surfaces have an inner ring positioned between two inner sealing deformable layers and an outer ring positioned exterior and concentric to the inner ring, the outer ring positioned between two outer sealing deformable layers. The two inner sealing deformable layers are configured to compress a greater amount than the two outer sealing deformable layers when a compressive force is applied. In a compressed configuration, the two inner sealing deformable layers fill in the crevices of the mating surfaces of a corroded flange connection thereby avoiding immediate maintenance for the damaged flanges. The inner and outer rings have grooves and ridges on upper and lower surfaces to retain and receive portions of the inner and outer sealing deformable layers in a sealed flange connection.

A single piece gasket is disclosed having a skeletal member, typically metallic, and a pliable body. The pliable body includes a first portion having a first firmness and a second perimeter portion have a firmer consistency. When such a composite body is placed under compression, the perimeter will tend to limit the flow of the softer inner material past the firmer perimeter region or portion of the gasket. In this manner, creep or overrun of the less firm portion material will be reduced.

A pipe joining system and pipe joint are shown in which two sections of plastic pipe, particularly molecularly oriented pipe, are joined. A ring-shaped elastomeric body is installed within a mating groove provided in a mouth region of female pipe section. The ring-shaped body is formed of an injection molded elastomeric material which is joined to a series of arcuate gripping segments which have teeth on an inner surface thereof which are designed to engage an outer surface of a mating male pipe section to restrain movement of the male pipe after assembly of a pipe joint. The gripping segments are separated by a gap which is open prior to assembly, but which closes during assembly. Each of the segments also has a positive stop feature to prevent over travel of the male pipe section relative to the female pipe section.

An electrically and thermally conductive gasket includes a resilient core including a plurality of sides, a heat spreader disposed along at least two sides of the plurality of sides of the resilient core, and an electrically conductive layer disposed along and/or covering at least a portion of the heat spreader, such that the portion of the heat spreader is between the resilient core and the electrically conductive layer. The gasket is positionable and/or compressible between first and second surfaces to thereby define an electrically conductive path and a thermally conductive path between the first and second surfaces.
