Shut off valve is a Chrome plated and lead-free brass structure with solid metal ball and brass pressure ring（Except for the handle and compression nut ）. More sturdy and durable than plastic valves. The Angle valve is most commonly used in the water supply pipeline of the bathroom, kitchen, toilet, and washing machine to provide cold and hot water. By turning the valve handle 90 degrees, you can control the flow of water into the pipe fixture. Every valve is leak-free quality controlled by the factory during the manufacturing process. For use in potable and non-potable plumbing and water distribution systems. Review: Well made, was compatible with old valve - I bought this valve to replace an old valve under my kitchen sink that was stuck and would no longer turn. The old valve was installed on 1/2 inch copper pipe. I was able to remove the old valve and leave the large nut and brass ferrule from the old valve on the copper pipe, and install the new valve onto the pipe by re-using the nut and ferrule from the old valve. This saved me from having to cut off the copper line (which was very short and would not have been easily done.) The threads and size on the nut from the old valve was identical to the nut on the new valve so it bolted right up, and saved me a lot of work. It did leak a drop now and then after installation, I was able to loosen and rotate the valve several times and re-tighten it, and the leak stopped. It was a small leak, one drop every few minutes. Now it doesn't leak at all. It had been leaking around the ferrule and was likely due to the fact that I re-used the old ferrule. So far it has worked great, the valve is a quarter-turn type valve and is easy to turn. The threads on the outlet of the valve were compatible with the line for the faucet with no adapters needed.

Will it replace the existing valve on it ?** A: It should. Make sure to get same size as the old one **Q: Does this have any lead ?** A: Our valve is lead-free, and the lead content is less than 0.25%. **Q: What country is this made in ?** A: I don't know which country it was made in, but I have to assume China. It is installed and the location makes it impossible to read if it is stamped on the valve, and I threw away the packaging. Sorry mate! **Q: Do you need Solder?** A: No these use a compression fitting, I used them and have no complaints… time will tell how long they last as I’m not sure they’re played brass or a cheaper metal. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made, was compatible with old valve *by M***. on March 6, 2024* I bought this valve to replace an old valve under my kitchen sink that was stuck and would no longer turn.
