Installation Note:Wrap the threads of the fixed orifice (or any stainless male pipe thread) with Teflon tape before installing into the flow controller. Without tape there is a high potential for thread leakage and more importantly, thread galling (damage to threads). Do not tape the first thread, and wrap the threads about 4-5 turns. Do not overtighten when threading the fitting into the flow controller.
