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

in line adapter for water filer or ice maker. perfect fit for residential applications and easy to install

A product bought on Amazon that actually arrives, actually works and is actually from the right manufacturer!!!

I needed this for my RODI under sink unit. I originally bought an EZ Angle Stop Adapter.. and that was a HUGE mistake. Leaked like crazy and nothing I did could stop it. This part however works like a charm, solid construction with no leaks! If you have a leaky EZ Angle Stop Adapter, this is the answer. A few things not list about this part is that the female 3/8 NPT comes with a nice rubber gasket, so no need to use plumbers tape on it. Also the entire PVC center swivels independently of the main unit, so you can position it perfectly even after tightening it down. Installation took less than 10 minutes.

Item was shipped quickly, arrived quickly, and was exactly as described.

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!

My intake valve on my water filter broke. So I first got a fitting like this that was all plastic. It was a total waste of money, the threads were wonky so it leaked and the whole thing cracked after spending almost an hour getting it on. So I got this one with metal attachments. Super easy to install, took all of 5 minutes, no leaks... I am totally pleased. It cost more but boy is it worth it. I cant recommend enough getting quality fittings if you want to make your life MUCH easier, and leak free.

No plumbers tape or brass nuts to fit and leak. This simply fits between the water line with push in fittings. Its so easy to fit and no leaking. works well too.

Worked perfectly to connect the refrigerator water/ice dispenser to the cold water supply under the sink. Description says no tools needed - of course you need tools. I needed a crescent wrench. Very easy to install - so happy I did my research and decided to take this on myself and not call the handyman - I would have been embarrassed, its so easy (granted, the copper piping was already in place). And so far its leak-free! (Its only been about 12 hours, but I did have to flush the system with 4 GALLONS of water, per the fridge instructions - oof.)

Product was well built and it fit my purpose exactly.

Used this to mount a Culligan undersink filter. So much easier and it IS NOT ALL PLASTIC !! The adapter that came with the filter was just not sturdy. This is what all filter mounts should come with. The brass to plastic connection is strong and provides peace of mimd. The 360 deg. mvmt. is a plus when installing in tight spots. Buy one !,
