100Pack Silicone Rubber Tapered Plug Assortment Kit, Rubber Plug Assortment Kit for Powder Coatings,Painting, Anodizing,Media Blasting Supplies

They do exactly what they are supposed to do.

I use them for powder coating and they do the job well

I fitted stainless steel ptfe flexible pipes on a number of my vehicles,, these are tremendous apart from one problem, if you have to disconnect them from the caliper, you cannot crimp them to stop flow of brake fluid. This is where I use these stoppers most.However they have been put into service in many applications as well since I had them.

I just needed one, but wasn't sure of size. Had some work done on the central heating and drain off output leaked slightly after completing. Used one of these to plug the output and, as is often the case, the drain off sealed itself once system got hot, which it probably wouldn't have done if leaking constantly.Very handy to have for any minor leaks in the future, and seem to be a bit easier to use than the pure rubber ones.

Used this to seal a hole in my gutter.Totally water tight now.Excellent value and will last a lifetime.Pliable rubber seals holes perfectly. Easy to insert and twist tight.Great value too.

The bungs have absolutely no grip. Put them in the ends of my diesel pipes,but they kept popping out, got very frustrated in the end .

Need assorted bungs like me? Then buy these, great sizes, easy to sharpe or trim. Doesn’t make coffee, I had to buy instant coffee for that, who knew?!

Not much to say, as in the pictures and they do the job.
