CYLINDRICAL GASKET MANUFACTURING METHOD THEREFOR AND INSERTION TYPE EXHAUST PIPE CONNECTOR USING THIS CYLINDRICAL GASKET

摘要

A cylindrical gasket (27) is equipped with: a reinforcing material (70) comprising a compressed belt like metal mesh (5); a heat resistant material (71) filling the openings in the belt like metal mesh (5) of the reinforcing material (70); and air holes that are dispersed throughout the reinforcing material (70) and the heat resistant material (71). The inner circumferential surface (23) outer circumferential surface (24) and circular end faces (25 26) of the cylindrical gasket (27) form smooth surfaces wherein the heat resistant material (71) and the reinforcing material (70) are mixed together and the respective volume contents of the reinforcing material (70) the heat resistant material (71) and the air holes in the cylindrical gasket (27) are 32 60% 5 58% and 10 35%.
