The present disclosure relates to a sealing assembly for sealing a space between a first machine element and a second machine element that is movable in relation to the first machine element. The first and second machine elements are arranged concentrically to each other. According to the invention, the sealing assembly is characterized in that it further comprises a conductive element that is used to establish an electrically conductive connection between the first and the second machine elements extending from the first machine element to the second machine element, and is mechanically connected at least in sections to the side of the seal facing away from the space to be sealed. The conductive element consists of an electrically conductive fiber fabric embedded in an elastomer matrix.

A sealing arrangement includes: a first machine element and a second machine element, each made of an electrically-conductive material; and a seal. The first and second machine elements are sealed against one another by the seal. At least one of the machine elements is made of an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production. The seal has an electrically-conductive support body. The support body has at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin.

Seal ring groups to be assembled with edges of through holes of a gasket includes a plurality of sealing groups. One of the plurality of sealing groups has an inner peripheral shape different from an inner peripheral shape of another of the plurality of sealing groups to distinguish one sealing group from another sealing group.

In accordance with at least one aspect of this disclosure, a fuel seal for an aircraft fuel system includes a seal ring of a metallic material configured to retain a shape of the seal ring under compression, and a coating of elastomeric material, over molded onto the seal ring and configured to conform to a shape of a sealing surface. In embodiments, the seal ring and coating can be configured to provide drop-tight sealing at a temperature of at least 400 degrees F. In certain embodiments, the seal ring and coating can be configured to seal one or more fuel system components of an aircraft fuel system.

A sealing device for sealing a pipeline arrangement, a method for the production of a sealing device, and a pipeline system including a sealing device and a pipeline arrangement. The sealing device includes a seal and data medium assigned to the seal with electronic data memory to which seal specific information can be or is written.

A connector for use in vacuum system is configured to fluidly connect a first opening formed in a first vacuum chamber to a second opening formed in a second vacuum chamber, the first opening of the first vacuum chamber being provided within the second vacuum chamber. The connector comprises a tube and a biasing O-ring. The tube has an outer wall to define a fluid flow path between first and second ends of the tube. Towards the first end, a sealing portion of the outer wall of the tube is provided. Towards the second end, an O-ring retaining point is provided along the tube spaced apart from the second end of the tube. The biasing O-ring is provided around and tensioned by the outer wall of the tube. The biasing O-ring is moveable along the axial direction between the O-ring retaining point and a sealing position where it seals the connector.
