May as well suck on a penny while drinking that lemonade

I had a guy come into the store last night and putz around in plumbing for twenty minutes so I wandered over to see if he needed some help. It's a good thing I did.
He'd replaced the saddle valve for his refrigerator ice maker with a threaded T sweated onto the copper line. In order to connect the plastic tubing he picked up a 1/4" compression by 3/8" MIP brass fitting and a 1/2" to 3/8" galvanized steel bushing. Fortunately I was able to stop him and find some brass fittings to make his connection.

For those playing along at home the reason you don't want galvanized and copper touching is that they will corrode each other. If you have to have both in the same line make sure to use a dielectric union so that the metals are isolated.
