I recall seeing mention of viton (?) seals being used in wing and header tank fuel drain valves. I drain my tanks for aircraft transport after each flight and as a result the fuel drain valves in the wings remain dry between flights. Would like a longer term solution than the month or two the existing seals last.
Looking for a supplier and part number.
Thanks for any help.

Take one of your old “O” rings into a gasket/seal business and tell them you want Viton seals of the same size. I had to drive 170 miles one way to Oklahoma City to find a source for them. I bought 100 of them since they were about 6 cents each at the time. That was 18 months ago, so prices may have changed. I changed out the tank drains on 2 Cessna 172’s and my Kitfox, all of which use unleaded gas, right after I bought them, and they are still holding.

S7 should have the latest drain valves with Viton. Amber colored is
correct. If you are not sure call the company and they will send new
o-rings at no cost. I forget the name of the company. sorry. The
header valve should have a touch of gas on it anyway. The drain
valves in the wings need to be replaced with a pipe plugs since they
serve no function and are just another failure point. The drain in
the header is plenty. That is where the bad stuff settles.
