useful for fuel conversion
Got this for my husband's rc airplane project since he wanted to change an old glow fuel tank over to gasoline. He used this brown stopper and said it fits the tank opening nicely without any loose spots. Only giving four stars because you have to be careful not to overtighten the center screw or it might distort the rubber, but otherwise it creates a solid seal.
