I bought from Home Depot a Glacier faucet that comes with 3/8 inch O.D. supply tubes. The supply lines from the wall have an outer diameter of 1/2 inches though. How do I connect the two?
This seems like a common enough question, but searching for "connector" I could only find this connector on Home Depot's site, which is from 3/8" to "M22". I'm not sure why "M22" is called that way, but its diameter is apparently 14mm, which isn't exactly 1/2".
Brass nipples on Home Depot's site seem to come only in the same diameter on both ends, e.g. 1/2".
(As you might suspect, I'm originally from Europe and have quite a bit of disdain for the imperial system and the US hanging on to it when the entire rest of the world uses metric.)
