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

Needed it for my Aquapurr automatic cat waterer. Im so happy with how everything worked out.

It was simple to install and after 2 months still no leaks or problems.

This product was easy to install and supplied my dishwasher with water without leaking Mission accomplished!

Needed to make a connection to my BRS-RO/DI system for reef tank. sink at home already has a RO system for everyday use so i need to make the connection from the bathroom sink. This saved the day, after looking at different Home Depots and other stores i shoulda just come here, heck i already do all my shopping here. Easy hookup no explanations needed, saved the day.

Some of these come with different sized inlet/outlet and you can use an adapter to downsize I believe, but if you have a Watts RO system with the crappy brass small/thin rounded handle that needs to be turned 3x or more from full close to open, this replaces it just fine with no adapter needed if your need is 3/8 on both sides. Quarter turn and you are done. Works great!

This valve worked perfectly while installing an under-sink 6 stage filter, and thats saying something, because the valve provided by the filter manufacturer did not.

Always worked

This is just what I needed. I also like that the middle (white) piece will swivel so the angle will line up perfectly. Installed in about 1 minute flat. Great product all around.

I ordered this valve to replace the the plastic T adapter that came with a water filter system

it is easy to install it works perfectly it is the part that I needed to make my water dispenser work it is an excellent invention indeed yes
