Black Malleable Iron Pipe Fitting Cap,Black Pipe Caps for Steampunk Vintage Shelf Bracket DIY Plumbing Pipe Decor Furniture(3/4 inch,20 Pack)

These are smaller than ones you’ll buy at a hardware store and don’t feel as substantial but are sufficient for decorating or if you do use them for actual plumbing, light pressure. One of mine wasn’t threaded but I checked them against the pipes from big box stores and they fit.

Work as they should

it is a pipe cap

It’s Black Pipe

Great product
