So I got an AI duster gas adaptor, and a can of Ultra Duster computer duster gas. The problem is, these computer dusters come with one of those easy-to-use spray adaptors on top. I cannot figure out how to take that part off so I can attach my adatpor onto the bare nozzle. I don't really want to just pry it off with my hand (I tried a little bit, and it is very tight so I don't think that's how I am supposed to do it), since I am afraid gas might explode in my face.
Does anyone know how to safely remove this?
