Review on 🔌 High Temp Silicone Rubber Tapered Plug Kit - 40 Pc Set, Ideal for Powder Coating & Custom Painting Supplies by David Ruwala

This is my second set of this brand. They are of exceptional quality and are primarily used to plug holes in items prior to powder coating. They seal very well and I have also used them as test plugs when testing vacuum lines. Surprisingly durable - I've reused many times in a 400F powder coating oven. Different sizes intersect so that all holes are covered from the minimum to the maximum dowel size.
