Glarks 40Pcs High Temp Silicone Rubber Protective End Cap Kit for Masking Off Holes During Powder Coating, Painting, Hydro Dipping, Media Blasting (40Pcs)

These are a good range of sizes. especially for automotive screw holes which has been the main part of the jobs I have been getting. The durometer is very low as well so it is easy to stretch them into the threads to make a nice seal. You can see in the picture that these pulled in and set perfectly. Not spec of coating got on the inside.At first I though they were a bit high in price since I know what it cost to actually produce them but for the job they do I will be buying again.

I think the only way this product could be messed up would be if they made them out of the wrong material and they melted during powder coating. Fortunately this is not the case. I never seem to have enough of these and this resolved that problem. It also gave me a nice easy way to store these and the ones I had purchased previously.Nicely done !

F ing awesome. Tried to find these for a while in town for my tractor but nobody knew what I was talking about. They are great for any hole that you don't want paint in. Using them for my dirt bike that I'm refurbishing and going to be using them on my engine block and heads when I paint those.

Made in China, but quality is pretty good and the transparent box they come in is nice and compact so it wont take up much room in my tool chest. I work on outboard motors and will use these stoppers to temporarily plug fuel lines and gearcase vent and drain holes when doing maintenance.

Purchased these so I would have a collection of different sizes. Good for plugging the drain holes in clay post, various sizes of plugs are needed. Although the really small ones are really to small for anything I do.

Using them to plug tiny holes when I apply cerakote to a gun or rifle. These withstand heat and are convenient

I bought these for keeping spray paint out of threaded holes. They work so much better that masking tape and are much faster to use. Been using over and over just cleaning after each use with soap and water.

If you know what to use these high temps for they come in handy and will serve its purpose.

Really quick delivery and exactly what is described

Great products used them for work

They work great I’ve used in high temps without problems

The look good. I have not used them yet

Love it
