John Guest Speedfit 3/8 x 3/8 x 1/4 Inch Angle Stop Adapter Valve, Push to Connect Plastic Plumbing Fitting, ASVPP1LF

I had to purchase this to use with the faulty one shipped with

I bought the wrong size, but it does its job even if I had to swap for a different one.

Excellent product, very good quality, it is the third time I have bought it, totally recommended.

I bought this to add a small filtered drinking water faucet to a bathroom sink (Culligan brand). It worked nicely for a couple of years and was rarely turned off/more or less just left in the on position the majority of the time. A month or so ago I was walking through the upstairs hallway where this bathroom is located and found myself stepping into a puddle of water that had randomly pooled in the carpeting. I was very confused as there arent any plumbing lines in the hallway. I finally found the culprit - this adapter/valve - which is now leaking water at a decent rate from where the blue handle meets the valve housing. Now I have a minor mold problem in the drywall/plywood sub-flooring :(

I had bought an ro filter counter top version few months back. I moved to a new house which had an expensive moen pull down faucet on which the filter failed to fit. I tried all possible solutions of finding different adapters which help to fit this filter to the faucet. However all attempts failed. Called the customer service and they gave a solution to replace the ro filter with under sink model or replace the faucet. I did not want to do that as it would costed more than 500 dollars. Finally I found this attachment which helped me fixed the ro filter from the under sink by pulling an extra pipe out for ro filter. I am so happy I found it and it saved lot of money.Its a nicely built product of great quality.Glad such products exists

I used this to connect RO drinking water system to my under sink water source. Works great and good quality. The plastic piece swivels around the metal piece, making it slightly harder to install.

This value worked perfectly and made my job easier installing my water filtration system. Great product would defiantly recommend.

Thank you thank you for this wonderful little valve! This is exactly what I needed for my existing RO water filter system under my kitchen sink and above faucet. The one I had came with the RO system and was horrible! It cut the faucet flow on the cold side by 50% compared to the hot side, I suffered with this on my to-do-list for a year before finally finding this replacement valve. Now my cold flow matches my hot flow, and installation was simple, this just drops in. The quality of this valve is much higher than the other one too, Im thrilled.

I went to two local hardware stores AND home depot. No one could figure out how to do this . My old contracting buddy on facebook sent me this link. Instead of HOURS, this literally took minutes. so easy. Love it1

excellent product, fit well and was exactly what I needed to get my RO system under my sink back online after installing a new faucet set for the wife. Remember, there are O-rings in this and you only have to tighten it about a half turn from hand tight. If you tighten it too tight, you may break or ruin the o-ring in the connector and cause leaks.
