John Guest Angle Stop Valve's directly connect RO units to the household water supply. It installs under the sink, inline after the shut-off valve. This clean, out of the way installation leaves faucets free for other use. To turn of water supply to the RO unit for maintenance simply close the ball valve.

Fantastic little valve By Chris W on 6/18/2017Chris W would recommend this product to a friendI wish that I would have picked one of these up a long time ago as it has made making water so much easier and at a great price.
Great non-permanent RO/DI connection By Kyle on 5/2/2017Kyle would recommend this product to a friendThis valve is a great way to connect an RO/DI unit to the cold water supply under any sink without making any permanent holes in your plumbing. This is much better quality than the ones you find in hardware stores. I highly recommend this valve for anyone looking to plumb their RO/DI unit under a sink, have the luxury of disconnecting it when needed, and being able to simply turn a valve and start making RO/DI water.
Excellent! By Eredus on 3/26/2017Eredus would recommend this product to a friendConnected in less than 5 minutes. No leaks and performs excellently! Would gladly recommend to anyone else looking for a very straightforward and reliable solution to connecting an RO/DI unit directly from an under-sink cold water supply connection.

very good By babnika on 7/14/2015babnika would recommend this product to a friendI really like the way this valve swivels around the stem making routing lines a lot easier. Not like others that can't that I have used in the past. I have two of these hooked up to one line to feed two of my RO units . verry impresed
So-so By GRC on 10/1/2014GRC would recommend this product to a friendLike the metal threads,but the valve didn't last 6 months!

Works without problems By Nish on 10/2/2013Nish would recommend this product to a friendAs a new reefer, I didn't know much and a friend suggested this, I searched this product at the homedepot and lowes or weeks as I didn't wanted to pay or shipping. But I couldn't find it. Then I ordered this with few other things I needed.
This product is well made, even better than the name brand stuff you can buy at lowes. Worked great 2 mins installation an I was up and running.

Great Adapter By Justin on 2/2/2012Justin would recommend this product to a friendThis adapter worked perfectly under my sink. No leaks and I am able to easily adjust the PSI for my RO/DI system. Much better than the saddle adapters!
Well worth it By Martin on 1/10/2012Martin would recommend this product to a friendEasy to install with no leaks. This is a good adapter to use as a supply line for a BRS RODI unit. I connected this in 5 minutes and I am a plumber's worst nightmare. If I can do this, anyone can.

These valves are designed to connect to standard cold water connections in 3/8", which are typical of sink lines, but washing machines may differ from this.
Have a great day!
