Abstract
A flat sealing gasket, such as a cylinder head gasket, for an internal combustion engine, has at least one opening, a cross-sectionally generally U-shaped armor framing the opening. The armor has legs straddling marginal edge zones of the gasket defining the opening. Each armor leg has an inner face in engagement with the gasket and an outer face oriented away from the gasket. A low-friction coating is provided on the outer face of at least one of the armor legs. Those sealing faces of the gasket which are externally of the armor are substantially free from the low-friction coating.
