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

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

Fantastic! I used this to replace the cheap plastic part provided with a Culligan water filter. All connections are secure and leak free. As a bonus the 1/4 connection to the water filter can rotate for optimum routing of water lines. Fast shipping - very satisfied.

No leaks it works as advertised

Glad to have this, it works great.

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

Good fitting easy to install did its job well. It did leak from the 1/4 tubing push to connect side for a couple days, but eventually worked itself out. I have installed many filter systems with the push to connect tubing. It is not uncommon for them to leak a little at first.

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.

My new RO system leaks from its cold water intake adapters like mad only a day after installed (by me). The supplied adapter is all plastic and the part that mates with the brass water outlet feels flimsy and its washer is puny compare to what I used to. So I called Premier and was advised the problem may with faulty washer and they will send me replacements. I knew the problem may be the design/durability of the adapter itself. I doubt a new washer will solve the problem. Even if it does, I have no confidence that it will not fail again later. So I took a chance and bought this one. Using the supplied brass adapters and teflon tapes from my RO system, I am happy to report that the leak has stopped. Tested for a few days now, still bone dry under the sink. So far so good. So if your RO system ships with a lousy adapter, save the hassle and buy this one instead. For a little over $10, the peace of the mind is well worth it.

If you are installing a Culligan water filter you must buy this adaptor, dont waste your time searching for one, going around all over the town, wasting your time and energy. Thank You JG Speedfit for making this Unit.

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.
