As part of my restoration, I want to replace the gaskets used in my pump. I haven't had issue finding the rubber seals for the doors, the sight glass and the ad glass areas, but am curious to see what everyone else is doing for the sight glass or any of the internal components. From what in understand, in my pump they used a rubber/cork gasket mostly such as the two gaskets to seal the sight glass (internal seal to the piping and then a second external seal between the glass and mounting bracket). I figure I could just get a rubber or some fabric style gasket off Amazon, but would prefer to try to replicate the original where possible.
