A static gasket and method of construction thereof is provided. The gasket includes a functional layer constructed of one type of metal having an opening bounded by an inner periphery an outer periphery. The gasket further includes a carrier layer constructed of a different metal than the functional layer. The carrier layer has an opening bounded by an inner periphery configured to receive the outer periphery of the functional layer in a line-to-line or loose fit. The functional layer is configured in substantially coplanar relation with the carrier layer with a first portion of the outer periphery of the functional layer being welded to a radially aligned first portion of the inner periphery of the carrier layer. A second portion of the outer periphery of the functional layer remains detached from a radially aligned second portion of the inner periphery of the carrier layer.

The cylinder head gasket includes a gasket layer which presents an inner periphery that surrounds an opening. The gasket layer has a first thickness adjacent the inner periphery. A combustion seal is positioned in the opening and extends circumferentially around an axis. The combustion seal is joined with the inner periphery of the gasket layer. The combustion seal has a height that is greater than the first thickness of the gasket layer. The combustion seal includes at least one seal body which is generally C-shaped as viewed in cross-section and is resiliently flexible for maintaining fluid tight seals with the cylinder head and the engine block. The C-shaped seal body presents a pocket which faces away from the inner periphery of the of the gasket layer for receiving combustion gasses during use to improve the fluid tight seals established with the cylinder head and the engine block.

A metallic flat gasket with at least one metallic layer and at least one filter element. The at least one metallic layer has at least one passage opening, which is covered by the filter element. The filter element has a mesh material.

A method and sealing gasket are shown for providing a sealing joint between a spigot section and a socket section of low pressure plastic pipe, such as drain waste vent pipe that require a minimum of tools and operational steps to complete. The sealing gasket is installed in one of the sections to be joined and the spigot section is inserted within a mouth opening of the socket section with the sections being pressed together in a single operation, thereby forming both the joint and the seal. The sealing gasket is a composite gasket made with one section of a hard plastic material and one section of a thermoplastic elastomer material. No glue or adhesive is required.

A cylinder head gasket including a stack of layers that includes a first functional layer having an embossed first sealing full bead and a first stopper, a second functional layer having an embossed second sealing full bead, and a carrier layer having an embossed carrier layer full bead. The first sealing full bead and the second sealing full bead are mutually superimposed. The carrier layer full bead and the first stopper are mutually superimposed. The carrier layer full bead when it is fully compressed has a maximum line load range included between 75 and 125 N/mm and assumes a flat configuration.

A metallic flat gasket with at least one metallic layer and at least one filter element. The at least one metallic layer has at least one passage opening, which is covered by the filter element. The filter element has a mesh material.

A multilayer metal gasket (28) for establishing a seal between two mating members, such as between a cylinder head (22) and an engine block (24). The gasket assembly (28) includes a primary functional layer (30) having an embossed primary sealing bead (38). A primary stopper layer (52) bridges the convex embossed portion of the primary sealing bead and is fixed relative to the primary functional layer (30) by welding (54) or clinching. A secondary functional layer (44) is paired with the primary functional layer (30) and inverted relative thereto so that its secondary sealing bead (48) aligns with the primary sealing bead (38) and their respective concave depressions open toward one another, with the primary stopper layer (52) sandwiched therebetween. A compression limiter (50) may be carried on the functional layer (44) or alternatively a distance layer (364, 464). The assembly (28) may include a tertiary functional layer (58) having a tertiary sealing bead (62) inverted relative to, and aligned directly with, the primary sealing bead (38).

A gasket assembly is provided including a first gasket layer and a second gasket layer having an outboard region and an inboard edge circumscribing an aperture. The gasket layers present a sealing bead between the inboard edge and the outboard region. A stopper layer disposed between the gasket layers is attached to the outboard region of the first gasket layer at an attachment joint and extends from the attachment joint to the inboard edge. A coating of sealing material is applied between the first gasket layer and the stopper layer. The coating extends from the attachment joint to the inboard edge of the first gasket layer to present a contact region immediately surrounding the aperture where the first gasket layer and the stopper layer are in direct continuous contact with the coating thereby preventing gas leakage and metal to metal contact between the first gasket layer and the stopper layer.

The cylinder head gasket includes a gasket layer which presents an inner periphery that surrounds an opening. The gasket layer has a first thickness adjacent the inner periphery. A combustion seal is positioned in the opening and extends circumferentially around an axis. The combustion seal is joined with the inner periphery of the gasket layer. The combustion seal has a height that is greater than the first thickness of the gasket layer. The combustion seal includes at least one seal body which is generally C-shaped as viewed in cross-section and is resiliently flexible for maintaining fluid tight seals with the cylinder head and the engine block. The C-shaped seal body presents a pocket which faces away from the inner periphery of the of the gasket layer for receiving combustion gasses during use to improve the fluid tight seals established with the cylinder head and the engine block.
