A gasket for a combustion chamber is provided. The gasket comprises a plated surface extending across at least a portion of the metal base. In the gasket, at least a portion of the plated surface includes a laser treated section with a first raised surface that protrudes away from the metal base and the laser treated section is arranged in a mid-span that is arranged between two cylinder openings.

An upper gasket member includes an upper base portion of an annular flat plate, an upper outer periphery portion diagonally extending to an upper side from an outer periphery edge portion of the upper base portion, and an upper outer periphery side annular portion of an annular flat plate extending in an extension direction of the upper base portion from an outer periphery edge portion of the upper outer periphery portion. Further, a lower gasket member includes a lower base portion of an annular flat plate, a lower outer periphery portion diagonally extending to a lower side from an outer periphery edge portion of the lower base portion, and a lower outer periphery side annular portion of an annular flat plate extending in an extension direction of the lower base portion from an outer periphery edge portion of the lower outer periphery portion.

A high capacity universal connector for use in connecting tubular members and a method for sealing the tubular members is provided. First and second tubular members are provided which each have ends that are brought into face-to-face engagement by a connector. A metal sealing element seals against conical surfaces at the ends of the first and second tubular members and enables the entire surface of the end of one tubular member to be bought into engagement with the surface of the end of the other tubular member so as to improve the bending and compression capacity of the assembly comprising the tubular members and the metal sealing element. A metal sealing ring for use in this assembly is also provided, along with a gasket retention assembly.

A sealing device for a wheel hub unit configured to form a static seal to protect the wheel hub unit from environmental contaminants. The sealing device including a shield that is coupled to a collar of the wheel hub unit. The sealing device having a cylindrical lateral mounting wall pressed into the collar, an annular seat with a blind end formed in the cylindrical lateral wall, and a sealing gasket positioned, inside the seat and compressed radially between the groove and the collar, and formed by a sealing compound to allow the formation of a bead against the cylindrical lateral wall in a transport and/or assembly configuration of the sealing device. The bead being movable into the seat by a scraping action exerted by the collar during the assembly of the shield.

A gasket to be attached between a cylinder head and a cylinder block of an internal combustion engine includes a pair of substrates, an intermediate plate disposed between the pair of substrates, and a spacer disposed between the pair of substrates. Each of the pair of substrates includes a cooling water sealing bead for sealing a cooling water passage surrounding a bore wall formed in the cylinder block. The intermediate plate includes a wedge portion formed in a shape corresponding to a deck surface of the bore wall of the cylinder block so as to be sandwiched between the bore wall and the cylinder head. The spacer is formed so as to extend in a cross direction S crossing an arrangement direction L of boreholes of the cylinder block without overlapping the cooling water sealing bead.

A gasket plate having a rigid orientation plate retaining at least one seal in a predetermined location in the orientation plate, and a rigid insert placed inside the seal such that the seal interposes the insert and the orientation plate.

A method of fabricating a metal cup includes a tool having an interior profile of a predetermined shape, the tool having a body forming an inner area; placing a metal sleeve within the inner area of the tool; securing the tool in a closed position such that the metal sleeve is unremovable; applying internal pressure within the inner area and within an inside of the sleeve such that the internal pressure exceeds a yield point of a material comprising the metal sleeve, the metal sleeve deforms into the interior profile; opening the body of the tool; and removing the metal sleeve from the tool in the open position; the metal sleeve maintains a deformed shape having an exterior profile that matches the interior profile of the tool.
