  • Two layer combustion flange
    Patent number: 5516120
    Abstract: A flange assembly adapted to be used in a gasket having an opening with an inner peripheral boundary including two flanges. Formed using a generally non-malleable metal, the flanges generally correspond to the shape of the boundary of the gasket body opening. Each of the flanges include a radially outer edge and a radially inner edge, an inner surface of each of the flanges adapted to be secured to the gasket body. The flanges may be mechanically or chemically secured to the gasket body. In one embodiment, the flange assembly includes a separate sealing element such as a wire ring. The inner edges of the flanges extend inwardly of the boundary of the gasket body to define a channel adapted to receive the sealing element.
