Re: Shut off valve - NO icemaker
I beg to differ, Sprucey. "Compression" refers to the fact that it compresses a washer against a seat, as opposed to a ball valve, a gate valve, butterfly valve, or something else. You most certainly can have a "compression" valve that's threaded on both ends.
Sprucey's advice is good. The original poster wants to get a valve with a compression fitting that will attach to the polyethylene tubing. If using a standard compression fitting (the type with a brass ferrule), be sure to use a brass insert in the pipe otherwise the pipe will squish down and you won't get a secure connection. You could also get a "shark bite" type fitting that has O-rings and barbs, which you just push the pipe into and it stays.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
