This is what should come with RO water kits. - I don't know why you're looking at this tee valve, but if you're like me - it's because your $400 RO kit came with some garbage fitting that leaked like a sieve in the middle of the night, leaving you with water damage and a huge headache in the morning. Better still, like an idiot I assumed I was at fault and reinstalled the tee after finding no obvious defects. Four hours later, I heard the drips. Something in the valve was leaking after a period of time, but after long enough just to trick you into believing it's okay. I hunted for HOURS in the local hardware store and online to find the right fitting. FINALLY I found this beauty. Well built, and extremely well engineered - it took me 10 minutes to install and has worked flawlessly. The metal section freely rotates along internal seals, so you don't need to worry about clearance for the valve during installation. The metal threads are properly machined, able to cinch down properly without fear of stripping some chinesium, and the push fitting gives that satisfying quality feel when the tube locks in place. I am *thrilled* with this part, and highly recommend it over anythign else you'll find. In a world full of headaches in unreliable garbage - this fitting is a bargain at twice the price. Review: Works as described. No leaks! Easy to install. - I tried 3 or 4 different option from different suppliers and this is the one to get! I had some kind of issues with the others I tried. This one connects to the 3/8 cold water line under your sink and allows you to connect the 3/8 cold water line to the facet while at the same time connecting the push connect water line to your RO system with a shut off valve. Super easy and no leaks! Great durability! Wish I had found this one first. Great product! Don't hesitate, buy this one! ## Features - WATER SHUT OFF VALVE: Our angle stop adapter valve provides an easy way to add a water feed supply from an existing 3/8 inch compression chrome supply stop valve.

Will this have the right thread count in US?** A: Yes I also double checked with a colleague of mine and he confirmed **Q: Dose the 2 metal connections (one male, one female) are Compression fitting or iron pipe screw fitting?** A: From the manufacturer's website:Angle Stop Adaptor ValvePart No. THREAD MALE COMPRESSION THREAD FEMALE COMPRESSION TUBE ODASVPP1LF 3/8" 3/8" 1/4"ASVPP2LF 3/8" 3/8" 3/8"The metal connectors are compression type with rubber gaskets. Easy to install. Leak free. **Q: 3/8" inner or outer diameter? The tubing that fits in the compression port is about 3/8" o.d. but about 1/4" i.d. so I'm confused** A: You need to use the outside diameter for this item. I used tho to connect a Whirlpool under sink water filter. All the tubing was 3/8" - anything I could find local was 1/4" for the tubing. I had to connect this item between the shut-off valve coming out of the wall and the sink. The fitting that came with it was to be placed between the wall and the valve, but it didn't have the correct size needed. **Q: Is the 3/8 the size of the supply line or the fitting thread? My supply line fitting threads measures at 1/2". I'm confused...** A: Is 3/8" the Male thread by 3/8" compression female by 1/4" quick connect If yours is 1/2" Following link might work better for you (same valve but it can be turn into 1/2" ) https://www.amazon.com/gp/offer-listing/B00N4NDQN8/ref=mw_dp_olp?ie=UTF8&condition=new ## Customer Reviews ### ⭐⭐⭐⭐⭐ Finally.
