I am baffled, probably because you guys are already familiar with it. I would use sealant on both sides of my fiber washer, but when screwed together would be a compressed very thin layer and gas would only be attacking it from the edge
A very good sealant for that would be that Seals-All stuff. Has been on a fiber gasket on my modified petcock for years
