1/2 copper in and 3/8 out
The 3/8 compression out is it desgined for faucet supply lines that have the nut with rubber washer. Standard sypply lines buy for faucet.
Or is there compression style fitting on the in supply and on the out the thread pitch for threaded supply lines.

If using the valve on the screen shot.
Ditch small compression ring and nut and use the standard supply line for faucet.

Using metal 3/8 faucet line = use small nut and ferule as shown.


Using a flex faucet connector with nuts on both ends = discard small nut and ferule.


Using a poly or pex supply line = discard the metal ferule and use the plastic ferule that came with the line.


Are you connecting an ice make or dishwasher? If ice maker you need the dual valve that has a 1/4 on one side or you will need to reduce it.


The braided connectors with nuts on both ends cost a little more but sure are easy to work with. Example: https://www.lowes.com/pd/Homewerks-...Stainless-Steel-Faucet-Supply-Line/1000578603

Thank you

Yes on the cold side supply for washer.
I did see the dual shut off valve.
One 3/8 on both outs
Another valve has 3/8 out and 1/4 out.

Is the supply on the dish washer end usually 3/8 as well?

Dishwasher = 3/8
faucet= 3/8"
ice maker needs 1/4"


Dishwasher is always connected to hot line.

Thank you sir.
Look like the connection on disher washer side had bigger flange nut.

Thank you sir.

The connection on the dishwasher side could be pipe thread. The tef tape on the tubing side with a ferrule compression fitting indicates whomever didn't have a clue.

Thank you sir.

Yes it most likely is a larger nut because the adapter it connects to is larger.


If you look at the the faucet supply hoses that I linked to above you will see that they also have one end that is larger.


Now whether you have the right part or not I can't tell from your image as it looks like like some Jake leg installed it initially and I have no way to know what they did. The dishwasher left the factory with the correct parts to utilize a dishwasher supply line.

Nothing jack leg about that dishwasher connection. The 90 degree elbow is a flared to IPS connection.

The leg that screws into the valve is IPS thread.

The leg that connects to the tubing is a flared connection.

To make a flared connection, using soft copper, you put the flare nut on the tubing, you flare the end of the tubing with a flaring tool. When you tighten the nut it compresses the flared end of the tubing against the machined end of the elbow to make a water tight connection.

Soft copper was used to give you flexibility in piping. Teflon tape which is a lubricant, not a sealer, was used to aid in tightening.
