Gaskets Sewage

When sealing raised or flat face flanges there are two choices of gasket material shape: full-face gasket  material and ring-type. The difference between them is that the raised face flange has a raised region surrounding the sewage pipe bore. The bolt holes are outside of this. The flat face flange has no such step, this seals on raised flange faces, but has an OD the same as the flange.
