Tnisesm 105Pcs 1/16" to 5/8" Silicone Rubber Tapered Plug Assortment Kits for Masking Off Holes During Powder Coating, Painting, Hydro Dipping, Media Blasting

Used with some small bottles that are otherwise hard to find stoppers for

Had ever size I needed and a lot more. Good price and these stoppers are a must have for all day mechanics. Can be reused after use too

This product has other functions.

Many different sizes, great at plugging coolant/oil/power steering hoses.

I use these to create drainage holes in my resin planter molds, which work wonderfully but I do wish there were tweezers in the set.When I place these, they're in runny resin and getting them to not only be where I want them, but keep them upright (especially the smaller ones). I have some tweezers I use but I wish they had a tab or something to make them easier to grab and it'd be nice I'd they came with a strong pair of tweezers. I do enjoy the versatility of the different sizes and the colors are definitely helpful in keeping them organized.Overall, I'd recommend picking up this set and a pair of strong tweezers that can handle the bigger sizes as well as the tiny ones. Otherwise it can be a little frustrating to use/place in resin projects.

Whether I need to temporarily plug a line or prevent paint from getting inside an orifice, these are handy to have around.The composition of the silicone is soft enough to easily press in place and grippy enough to stay put.The range of sizes is excellent.And with the tapers, these should accommodate most any size between.
