Swpeet 100Pcs High Temp Silicone Rubber Protective Tapered Plug Assortment Kit, Masking System Kit Perfect for Powder Coating, Painting, Anodizing, Plating & Media Blasting

Used this to replace a plug on an air conditioner. After market part was about $40. This kit had a nice assortment and cool colors. The plug worked, it saved me money and I have a bunch of other plugs I can use. Good deal.

I Cerakoted a barrel and they worked great!

Swpeet 100Pcs High Temp Silicone Rubber Protective Tapered Plug Assortment Kit: I bought the entire kit because I needed a few plugs for various hobbies & household uses. They worked best as stoppers for small glass vials where the plastic caps leaked. They worked well as temporary insulators for light electrical work. The one use where they failed was as a vent hole plug on a 5-gallon heavy duty plastic gasoline 'can.' The plug eventually reacted with the gasoline and crumbled into the 'can.' Had the pour filter not caught the pieces, they would've gone into my generator. So, no more contact with petroleum based liquids. Otherwise, the plugs are good to have around.

Comes with a nice assortment of tapered sizes from 3/4" on down. Chose this brand because it seemed like all the others started at 19mm (3/4") and then jumped down to 12mm. I was particularly interested in the larger sizes, 19mm, then 16mm to plug a hole in a drain pipe we removed a failed dishwasher from.The plastic box that comes with it, is pretty nice too, with a decent clasp to keep it closed.

Bought to use in sewing machine to repaint. Should work well.

This is one of those tools you never knew you needed, but you can't live without. It is SOOO nice to have these plugs to seal up all of the leaking holes in your life. These are intended for powder coating or painting, but they're also incredibly useful for wrenching in the garage. Brake caliper banjo bolts, power steering lines, fuel hoses, and carburetors - these plugs have saved me from a lot of nasty messes and helped with both cleaning and diagnosing fuel issues on my old bikes. The silicone is heat and chemical resistant. Just wipe them off when you're done.

A very good solution for plugging holes when doing repairs. Love that they are silicon and very well seutied for stopping leaks and drips.

Worked good did the job
