Why all this talk of doubling up gaskets. In my gasket box, I have cork and composite gaskets in a range of thicknesses from 0.035, 0.040, 0.090 and 0.100″. Also I have copper /asbestos central gaskets in thicknesses ranging from 0.115, 0.125 and 0.135″ plus additional thin washers at 0.035″
Have you checked with the spares scheme on available sizes?
