A thermally and electrically conductive gasket of a gasket set configured to be mounted between a faceplate and backing plate of a showerhead electrode assembly includes an inner gasket configured to be mounted on an inner electrode of a showerhead electrode assembly. The inner gasket includes a plurality of concentric flat rings connected by a plurality of spokes. A first annular gasket surrounds and is concentric with the inner gasket and includes a flat annular ring having a plurality of cutouts. A second annular gasket surrounds and is concentric with the first annular gasket and includes a flat annular ring having a plurality of cutouts. A third annular gasket surrounds and is concentric with the second annular gasket and includes a flat annular ring having a plurality of cutouts. The gasket accommodates gas injection holes, alignment pin holes, an alignment ring groove, and/or threaded holes.

A gasket (20) is provided with a uniform thickness spacer layer (66) between two metal upper active layers (78, 80) and two lower active layers (82,84). Each of the layers has aligned openings. A first tab (158, 140) is formed from one of the upper active layers and is located in a first slot (168) in the spacer layer. A second tab (132, 150) is formed in a flange of one of the upper active layers and is located in a second slot (174) located in the spacer layer. A third tab (190, 208) is formed from one of the lower active layers and is located in a third slot (212) located in the spacer layer. A fourth tab (176, 194) is formed in a flange of one of the lower active layers and is located in a fourth slot (218) located in the spacer layer.

A bead gasket for sealing off a gap between a first component and a second component, the bead gasket including: a first gasket layer including a holding element; a second gasket layer comprising a complementary holding element; and one or more folding portions which connect(s) the first gasket layer and the second gasket layer, wherein the first gasket layer, the second gasket layer and the respective folding portion are formed in one piece, and the gasket layers are or can be folded one onto the other by folding over the respective folding portion, such that they face each other in an axial direction, and wherein the holding element and the complementary holding element are in or can be moved into a holding engagement with each other based on a positive fit and/or frictional fit, in order to secure the gasket layers against diverging from each other.

A layered head gasket includes a gasket core, a head-layer, a block-layer, and a plurality of apertures. The head gasket may be useful for sealing an internal combustion engine having a cylinder head, a cylinder block, a plurality of combustion chamber passageways, a plurality of coolant passageways, and a plurality of oil passageways. The gasket core is made of a copper sheet. The head-layer may be made of spring steel and may be fixed to a top side of the gasket core, being configured to interface with the cylinder head. Likewise, the block-layer may be made of spring steel and may be fixed to a bottom side of the gasket core, being configured to interface with the cylinder block. The plurality of apertures may pass through the head-layer, the gasket core, and the block-layer.

A sealing gasket includes an outer flange, an inner flange, and a seal. The outer flange comprises a first surface and a second surface, parallel to the first surface and comprises a first opening, centered on a first opening axis, wherein said first opening is ringed by an inside edge of the outer flange, connecting the first surface and the second surface. The inner flange, is arranged inside the first opening and the inner flange is connected to the outer flange through at least one junction tab, the inner flange, the outer flange and each junction tab being made of metal. The seal, is made of elastomer, provided on the inside edge and protrudes from the first surface and the second surface.

A tube assembly comprises a tube having a tube flange securable to an associated mounting surface of a turbine engine component. A first seal is provided at the bore interface between the tube and a fluid port of the engine component. A second seal is provided at the flange interface between the tube flange and the tube mounting surface of the engine component. The second seal includes a gasket having a sheet metal body with corrugations projecting from the tube facing side of the gasket. Tabs are distributed along a periphery of the gasket for resiliently holding the gasket on the tube flange with the tube facing side of the gasket facing the tube flange.
