ABSTRACT:
A high temperature gasket structure particularly useful in automotive carburetors but useful in other applications in which the gasket body is formed from a special type of semirigid asbestos board having a minimal elastomeric binder content, and with the bolt hole areas densified in part by embedded steel washers in the gasket body to minimize carburetor flange flexing and maintain high torque retention under heat. The gasket structure is intended to serve as a heat insulator and as a partial sound and vibration dampener and can be formed, when required, with upstanding beads to further minimize flexing of the carburetor flange while maintaining a seal.
