I got 50 feet of refrigeration copper. I need to figure out the fitting I need to go from my faucet to (I guess 3/8" hose). I have a swedging tool so I should be good with just a hose clamp on the tube end.
I just stuff my 3/8" vinyl tubing INTO the faucet and it stays without issue. I don't use a fitting on mine. But mine is a utility sink and doesn't have any screens or anything to inhibit my tubing from just going in it.
