Easiest way to go from 1/2" ball valve to 1/4 inch compression fitting?


I'm planning to replace a saddle valve that connects my 3/4" water line to my furnace humidifier via flexible copper tubing.

I'm going to install a 3/4-1/2-3/4 tee, and then the 1/2" ball valve on the 1/2" side of the tee leading to the humidifier, but then I need to get some kind of reducer to connect the 1/2" ball valve to the 1/4 inch compression fitting that is at the end of a flexible cobber tube that leads to the humidifier.

I went to two Home Depots and the only thing they have to go from the 1/2" ball valve to 1/4" compression is to sweat an MIP female fitting onto the ball valve and then connect a threaded 1/2" male MIP fitting to that, which then has the 1/4" compression connection on the other end.

Isn't there a way to go directly from the ball valve to some kind of reducer that connects to 1/4" compression fitting, w/o messing with the MIP threaded fittings in between?

Or maybe I just need to try a different store than Home Depot? Would Menard's have more fittings than an HD?

You are thinking about this wrong.

Once you have the T and 1/2" stub---simply add a 1/4" shut off valve --they are exactly like the shut offs under your sink---except they have a 1/4" outlet for the little copper line.

Use a 5/8 comp x 1/4" comp, quarter turn straight stop.

Do they have quarter-turn ball valves that are 1/4"? I was hoping to use a ball valve rather than the standard shut off valve that can leak down the road.

I didn't see that at Home Depot. Seems like the smallest quarter turn valve is 1/2" at HD. Do other stores carry a 1/4 inch ball valve?

Thanks everyone for the suggestions!

You have to go to the right section....they keep that kind of stuff usually in pull out drawers...

Try the automotive parts house. Or a real hardware store. 1/4 turn ball valves are available in 1/8 to 6 inch

I know that the Depot does not sell 1/4" 1/4 turn shut offs--however in the fitting section you should find a 3/8 to 1/4 adapter.

Hmmm, just checked Menards and no luck there finding the 5/8x1/4" comp. quarter turn valve. They did have more valves than the Depot there, but not the one I need.

We don't have a Lowes nearby. Next I may check our local Ace Hardware, but it's not a very big store so I doubt they'll have it.

May have to find a plumbing supply store somewhere.

Look for a screw on 3/8 " to 1/4" cap--Job done.

You could buy a rough in box for an ice maker. It has the valve you want. Take the valve out of the box and solder it on your tee.
