Here is what is known as an explosion whistle that will screw into the primer hole of a gas engine. When activated it will make a whistle sound when the engine fires. There might be a very slight crack in the threaded mounting area. Check out the pictures and see if you need it. The bell is about 2 in diameter. 1/8 pipe mounting, those threads might have a slight crack. The valve seems to work fine but I haven’t tried it under any pressure. “AS IS” what you see is what you get. For questions 419 789 1159. Thanks for looking at this listing!
