I have seen a few posts about left hand thread by right hand thread nipples. What is the reason some regulators are manufactured with left thread and some with right threads. I know in some cases when left threads are used they are usually used as a safety to avoid connecting dangerous gasses where they should not be connected. In this case I am trying to connect several c02 regulators together and I want to make sure I am not missing some safety factor. I am having a tough time finding a left thread by right thread nipple so my next step is to find a left thread pipe die.
