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

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

Used this adaptor valve to connect my existing Watts Premier RO-Pure to the new Moen kitchen faucet I had newly purchased. A well made product and easy to install. Highly recommended.

Good quality fitting, as usual with JG speedfit fittings. I used this to tap into my under-sink coldwater line to install a RO/DI system on my pex line. This will easily work on PEX and braided hose line, right after the cold water shut off valve going to your faucet. Far better quality than the cheap plastic pieces most home RO systems come with to tap into the cold water.

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

The JG Speedfit product SAVED ME. I needed to purchase this adapter to complete a Filtrete Model 4US-MAXL-S01 setup. Filtrete/3M sends a piece of crap plastic that never completely sealed in my under sink setup (it would leak no matter how much I used sealing products) and was easy to thread. I was so glad to find something with metal for the threaded connections while still providing the push-stop valve I needed for the water filtration system. And the little open-close valve is perfect! It allowed me to check for any leaks before hooking up the push-stop. THANK YOU, JG!

My plumber said this piece saved the install of our water system

Everything was sized as advertised, with exactly the same difficulty of installation as any other adapter. You need to allow space for the valve handle, since its bulkier than the rest of the fitting. The plastic parts dont feel cheap, and the valve was firm enough that it wont be turned accidentally, but still not difficult to turn. This is great under the sink with cleansers and things that might bump into it. If youre looking for a valve to be turned on and off a lot, this is probably not what youre looking for, but its an excellent choice for under-the-sink fittings that will only be used during maintenance or upgrades.

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

These are hard to find locally, fit and finish was great worked well cant ask for more.

This was a perfect fit for my application- connecting a R/O filter to my kitchen sink. No leaks and an easy installation. Saved money vs. trying to piece something together at the hardware store too. Fast shipping as always. Well worth it!
