Review on 🛠️ 10-Pack Black Malleable Iron Cast Pipe Fitting, 1/2 inch x 6 inch by Alffun - Perfect for DIY Decor or Industrial Vintage Style by Eric Rodriguez

They have chairs with theirs Made by my own hands, industrial look. We used 1/2" black tubing and fittings. We ordered them but had to send them back because they were all black, not the hardware store ones, so didn't match the rest of the parts. They are also not as thick as the black tube. If you're happy with solid black, as well as a little thinner and lighter, then you're fine. Plain black pipe has an oil base that you can leave on or remove, but you must spray polyurethane or it will rust. You do NOT have to worry about them as they are black and oil free.
