Ice maker install

I'm stumped. I have a 40 year old roughed in copper line sticking out of the sheetrock behind the fridge of my rental property. The new tenants want it connected to their fridge. I dont want to put a box in and would just like to put a stop valve in....not those needle or saddle valves. Problem is..I cannot find the combination of parts to do this without soldering...sharkbite or compression at big box stores. It seems the 1/4" shark bites are larger diameter and made for PEX...brass fittings/valves seem to be made for PEX too. I know I'm doing something wrong here...can someone point me in the right direction? Thanks

this is what you need, available at any big box store

use the valve Rickyman has provided and buy this kit and the compression sleeves...this is from ho depot

Switch from copper to pex and install said valve.

Reason I say to switch, pex has more leaniancy behind your fridge, copper is more rigid and doesn't have a lot of give to it.

Btw, it's a 1/4 inch outlet that you need off the angle valve.

I just went through the same issue over the weekend, using a 1/2 × 1/2 × 1/4 compression fitting similar to the one shown above by Rickyman. My problem was that the end of the 1/4 copper line was wavy and luckily I had enough slack to keep trimming it back until the compression nut and ferrule would slide over the tubing.

I do agree that a flexible line is the better way to go, but the compression fitting should "fit".

Use a flaring tool to re-round your pipe or a crescent wrench works also

The connection to the copper pipe with the stop valve is where I am having trouble. How do I connect the copper roughed in line to the stop valve? Copper is 1/4" and the stop valve is 1/2. I haven't found a coupler or fitting which will work....I'm sure I'm missing something...it cannot be this difficult.

if the copper line that is coming out out of he wall is 1/4'' copper

If you use plastic tubing from valve to fridge you must, use these plastic Ferrell instead of the brass Ferrell
