Hello,
I'm looking for some guidance on the proper use of a left/right nipple and coupling to join two rigid pipe assemblies. As I understand it, the left-handed end of the L/R nipple and the threaded end of the other pipe assembly should be in line with just a small gap between them, maybe 1/4" for 3/4" iron pipe? Then you have pry them apart to insert the L/R coupling, and tightening the coupling draws the two threaded ends together. Do I have this right? It seems like the two assemblies must have some give in them in order to be able to insert the L/R coupling.
Thanks, Wayne
