Not 100% positive, but I think regular compression couplings/connectors stopped being code compliant for outdoor use a few code cycles back. Most people now use the actual rain tight stuff with the blue or yellow gaskets.Are we talking about true RT fittings that are gasketed or the common compression fitting that we used to call RT?
There’s a gasket on the inside. Kinda like a sealtight connector, except it fits over pipe.I've never seen (in person) or touched one of the "new" RT fittings, they still have that split ring in them? Where does the gasket/o'ring (what ever makes it RT) go in the fitting?
Your serious? How much pipe are you running a day like that??????If you use the tubing cutter and cut only partway through the wall and snap the tubing off at the score line, it leaves a slightly bigger smoother radius on the cut ends with minimal effort. The Rigid cutter works onEMT conduit from 1/2 to 2”
