Easy to install - works like a charm.
o-rings bulged out past the fitting head and washer sides with only minimal torque. Used large diameter washers to ensure reasonable seal. Also, star washer would have cut into o-ring without flat washer. Seems to be holding ok.

Dont think about trying to use these as a sump fitting on a cross-linked poly gas tank. The round o-rings will not seal. They just deform out from under the nut and head and the fitting leaks. Not flight worthy. Dont ruin a tank for this. The brass is good quality and the threads and other machining are first rate, but this wont seal.
Mine didnt come with the rubber gasket, so it was unusable.
