Clean the threaded male end of the pipe connector. Ensure that it is free of any burrs and dirt.
Wrap the Teflon tape around the male pipe threads using a clockwise motion--the same direction in which you will be attaching the female end of the braided stainless steel hose. Use a couple of revolutions of tape, but do not over-coat the threads.
Tighten the flex hose to the pipe fittings, first by hand, then with a pipe wrench. Ensure that you get a firm, tight connection in the fittings without overtightening them.
Repeat the earlier steps to connect all the plumbing in your installation.
Turn on the water supply, and check your installation for leaks. Retighten fittings as necessary.
