Has anyone ever figured out the reason there is a thin paper gasket there?????
In all the time I've been involved with this stuff I've never heard a definitive let alone a logical answer to that question.
There is "NOTHING" to seal there!!!
That reminds me of the boiler patch that was on a US war ships steam boiler that the Japanese captured. They copied the design right down to the patch. No need for it on a new boiler but it was there so they just included it in their copies.
