  • Gasket with compressible sealing member and hard support layer
    Patent number: 6354599
    Abstract: A gasket is formed of a gasket member extending substantially throughout an entire area to be sealed, a compressible sealing member, and a hard coating. The gasket member has a first hole to be sealed, and a plurality of second holes for allowing bolts to pass therethrough situated around the first hole. The compressible sealing member is disposed on at least one side of the gasket member to completely surround the first hole without surrounding the second holes. The hard coating is disposed on the gasket member at the same side of the sealing member to surround the second holes. The hard coating is formed independently from the compressible sealing member and has compressibility less than that of the compressible sealing member. The gasket can be formed easily at a low cost.
