under the sink reverse osmosis installation

I just bought a small 5 stage reverse osmosis system that installs under your sink. In the picture is the adapter they sent for the install. the 2 stainless pieces are removable and will accept a 3/8" supply line, or a 1/2" supply line. I didn't realize that the shutoff valve and supply lines I have in the home are still 7/16" is their any adapters or anything I can buy to get from the 7/16" to the 3/8" or 1/2" that the ro system will accept.

7/16 compression is hard to come by. Ideally the angle stop would be changed to 3/8.
Here are links to a universal hose that includes adapters. I would buy the hose kit just to get the adapter needed, 7/16 to 3/8 compression:

Homewerks Worldwide Universal Connector Kit x 20 in. Faucet Supply Line Braided Stainless Steel-7223-20-38-5 - The Home Depot


To install the adapter ensure the rubber washer is inside and tighten 1/4 turn only past hand tight, maybe a little more after checking for leaks.

Thanks for the help @handyone that kit and a longer supply line took care of this until I can change the stop.
