I recently bought a blickhmann toptier and the burners came with some 1/2" diameter T's to build a gas pipe and split off the gas. I'm using black pipe but I was wondering if anybody knows if the T's that came are stainless steel? The outside is dull but the inside threads are pretty shiny but I'm not sure if it's just shiny because of the thread cutting process. If the T's are stainless then I rather use one to make a bleeder valve for my pump and replace the gas splitter with just black steel elbow at the top since I don't need a T at the top.
