#3 EPDM and #5 Neoprene Stoppers
I purchased the wrong ones 1st time which I am sure I will use or give to a friend. But, I needed size #5 for for my 4 liter wine jugs that I use to fill my kerosene heater. With the Green Neoprene Rubber Stoppers I've drilled 2 holes. One to a length of 3/8 soft copper tubing to go from bottom of the glass jug to the top my removable filler tank. The other hole in my stopper I drill a 5/16 hole & put an old bicycle inner tube valve stem in. So now I can use my foot air pump to fill tank with out the funnel blocking the view of the filler hole. But now I can mark (tape) my glass jugs where I can put the correct amount in the jugs for a 12 hour burn time.
