20 Pack 3/4 Inch 90 Degree Black Elbow Threaded Pipe Fittings, Cast Pipe Fittings for DIY Furniture Decorative, Steampunk Industrial Vintage Style.

This company makes the best black galvanized fittings I've ever used. Clean, oil preserved, sharp threads that fit sweet without leaks. Paid not have to use Teflon or pipe dope to gain seal. Based on full five thread connection technique.

Great price and good quality for 3/4” black pipe closet rods. Not for gas lines

These are great for decorative reasons, but do not expect to be building ladders out of it. The material is as thin as it gets. I'm impressed that you even can make cast iron this thin. Also, their mold for casting is a tad deformed (not quite circular), but the thread is true. One out of the twenty pieces that I got was bad, and should have been scrapped at the factory.
