140PCS 9 Sizes Silicone Plug Set, Silicone Rubber Tapered Plugs 1/16" to 3/4" High Temperature Resistant Hole Plugs for Industrial Powder Coating Plugs Spraying (140)

I use it to plug my silencer to clean them. Different sizes for different opening then fill them with ‘the dip’ overnight, rinse it, dry it. Keep any liquid to leak. Great product.

Need to remove the rust from my CT90 gas tank. to do that I need to plug some holes and pour rust remover in the tank and let sit for 24 hours. these were just what I needed and moderately priced. You get a decent selection of sizes and 140 pieces. they are very flexible so you can stuff them in the holes and make a good seal. also would come in handy for painting where you need to plug holes before spraying. for 12 bucks I would say its a pretty good deal.

Worked perfect for automotive application

So far so good work well

Wry god sizes, work well

I got these for plugging small holes in stuff I need to spray paint. These stoppers cover a wide range of holes from about 1/2" down to maybe 1/16". They are flexible with a narrow taper so they actually stay put without falling out. Much better than rolling a plug out of a tissue or paper towel. They are lint-free, and the silicone releases paint overspray neatly. These are nice plugs. Highly recommended.

I got these to insert into threads and ports of parts that I am powdercoating. They would also work for spray painting, but their being silicone makes them heat resisitant which is perfect for powdercoating. I'm not really sure that I get why there are different colors because it doesn't matter what color they are, but that also means I don't care. They work well for the purpose and there are enoigh variations in size to plug up holes on most parts that will fit in an oven.
