High Temp Masking Supply 160 Piece Silicone Rubber Plug and Cap Set - 1/16" to 3/4" Range - for Powder Coating, Painting, Ceramic Coating, Sealing Holes - Non-Toxic, Flexible, Reusable

The size of these are great, the durability is endless, functionality is perfect, and easy use and reusable …,

Bought this kit because I do small restorations of many items and often get those items powder coated. These help me plug threaded holes and bores to protect them from wet spray and or powder coating application. After coated, simply flexing and squeezing these tends to flake off the coating and they are almost like new each time. very helpful with the many sizes.

I keep a bag or 2 of these on hand as I’m a auto tech and these are great when you are taking something apart and it’s leaking everywhere you can shove a plug in it and you good to go i deffinly recommend and they are cheep enough when u got to leave them in some thing you just by more

Product is as described, work good for my needs.

They help up to the heat while powder coating and didn’t melt but they would expand and fall off or pop out

Needed these to plug hoses on my car in order to do my spark plugs without having to drain the coolant out of the system. Fortunately, the plugs did what I expected them to do..... plug the holes. They appear to be good quality, no issues thus far.

exactly as advertised . worked great

Use these when pulling and disassembling engine to block off holes and they work perfect for plenty of sizes. Pulling lines off of transmissions and radiators.

They work as expected. Would recommend

Worked as required to powder coat

Motor vehicle restoration - used the end caps to minimise fluid loss.

Happy with purchase
