These things plug up vacuum ports of various sizes. They don’t hold a high amount of pressure so some things I put them on didn’t work. But they work for what they’re designed for. Just don’t put them in your orifice(s), they are a challenge to get out. I wish I’d known that before getting some stuck. It can be expensive to have a real doctor take them out.
