The ice maker line to my refrigerator currently has no shutoff valve and I'd like to add one but I can't figure out what size the connector is. I purchased a 1/4 inch valve since the ice maker connector I have says 1/4 FCM on it but it did not fit. It looks more like 1/8 inch, but a 1/8 inch valve doesn't fit either, although it is very close. Where can I find information about water pipe sizes, there must be some standard?
My fridge is a GE CFCP1NIZSS: http://products.geappliances.com/ApplProducts/Dispatcher?REQUEST=SpecPage&Sku=CFCP1NIZSS
The copper water line I am connecting it to has the exact same measurement as the fridge.
This valve was extremely close in size, and just barely didn't fit: http://www.amazon.com/gp/product/B005C0J3XI/ref=oh_o02_s00_i00_details
Okay I thought that searching the internet for 1/4" OD Valve Male Female would get me what I need but I am getting no results so I've reopened the question! Can anyone give me a web link to a product that will fit? I've added a photo of the current connection where I'd like to add the valve. Thanks!
