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

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

-I’ve been using this product for almost over 10 years , I’m happy to be able to find it here on Amazon and it works perfect. it’s very good quality! Buy with confidence!

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.

Glad to have this, it works great.

All I can say is OMG I wish I had started with this valve instead of with the metal one that got all corroded and nasty and was so hard to tighten in that small space under my sink!!! Love it - installed VERY quickly and works perfectly, so when I am changing out my water filter stuff, I can easily shut the water supply off.

Wish it has turning tight, but everything is good.

This worked fine, and the plastic valve rotates around the metal fitting, so you can swivel it around to point where you want it to.

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.

Product was well built and it fit my purpose exactly.

Bought a new sink and the fitting for my water filter didnt fit the 3/4 connections. Local hardware didnt have these JG fittings, which I needed as my water filter uses the 1/4 plastic tubing. Bought this, and in less than 5 min had my water filter hooked back up.
