Customer Reviews for STZ 1/2 in. x 3-1/2 in. Black Steel Nipple

Threaded black pipe what else can I say, It worked.

I bought 2 flanges to mount on a pair of 5”x8’ timbers to make a wall tent frame. These are advertised to be rated up to 214psi. I mounted the flanges and threaded this fitting in both flanges. I went to pick up the frame and the pipe sheared off flush with the threads of the flange. There’s no way I exceeded 214psi, these products are Chinese junk.
