This is a 1/4" x 1/4" x 1/4" Male Run Tee. When you look at a tee it has three connections. Two run left to right through the fitting, the other branches off. So here you see a male thread run and a right quick connect run. This fitting also has a quick connect branch. So the only different part is the run on the left and it is a male thread.
