This is what we see with the AFM Base Gaskets.
.018" AFM compressed thickness compresses to .011" to .014"
032" AFM compressed thickness compresses to .017" to .020"
060" AFM compressed thickness compresses to .029" to .034"
We machine the base gasket surface of the cases to make them flat and sqauare. When the cases are flat the AFM gasket does not require ANY sealant.
