They are not 100% sanitary, what I am going to do is, cut most of the threads off the fitting using my chop saw. Then drilling both sides of the 1/2 inch fittings to 7/8, then tig welding a 1 inch triclover to each end.
1/2" fittings are closer to 7/8" with the threads, so its pretty easy to just drill them out on the press with a 7/8 drill bit. And the inside diameter of the 1" triclover is 7/8"
the reason I am going to keep them 1/2 is because my chugger pumps are 1/2". Even though I plan on modifying those too with triclovers. The inlets are a little small (maybe 1/4") and can use some opening up.
