JIUWU RO Feed Water Adapter PT 1/2-Inch(3/4'') to 1/4-Inch Ball Valve Faucet Tap Feed Reverse Osmosis

Hi , I bought this fittings but not 3/4 It’s not working , the description was wrong

I had a leaking valve from one of the other Amazon fridge water line kits. This is the replacement piece and it works great. No more leaking.

The Tee union joint part constantly leaks which makes this non-usable

The male thread on the ball valve part is actually 1/2, not 1/4. And the male and female threads of the straight tube are both 3/4, not 1/2. I don't know if I received the wrong one or not. But I was able to connect it to a different part under my sink, which still allows it to serve its purpose. However, it leaks, I think due to poor design. Because these are two separate parts, once you screw in the ball valve part into the straight tube, it extends about halfway inside the tube. What happens is some water is being blocked by that overextension inside and thus some water being pushed under the overextension and out, creating a leak. I was able to slow it significantly by using A LOT of teflon tape and tightening it hard to where it's not a big issue, but I'll replace it down the line and try something else.

It is a valve. I got the wrong size which is my fault but it is well made.

Probably works, but I want pleased with it when I got it. It's just a fitting drilled and tapped and then it comes with a valve to screw in the fitting. I don't think there is enough thread engagement. Also the valve will only accept a plastic tube, you cannot thread on a hose that already has a compression fitting. The part was just not what I thought it was and poorly made, in my opinion.
