Will work well for hole plugs for painting or whatever you want.

We used these to block holes left in the floor of each room left after removing radiators. It’ll be a while before we refinish floors, and the kids were losing a lot of small toys into the abyss (on purpose and on accident). These work a lot better than tape, and because of course the holes aren’t the same size I ordered several other sizes as well. Happy they are sold in five packs so we don’t end up with too many extras.

I was going to use to plug PVC pipe while heating in order to bend . The ID of the pipe is trade size National Electric Standard 2" PVC and the plugs are to small. Will find another use for them i guess.

I was pleasantly surprised with the construction and quality of these plugs. I used them and a light acid bath of vinegar and also some rust dissolving chemicals. They held up well with no issues.

These are very stiff and solid a little hard to drill through like it heals the wound slightly, I used to plug a hole in firewall and pass through some cords. They can take a beating and lock in pretty solid.

Great silicone stoppers, a little hard, but with high temp rating you get that, they should last a very long time.
