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

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

My first valve leaked and contacted the seller. They replaced it for free with shipping included and the new valve works perfect and is a 5 min install. I would buy again.

I used this on a bathroom sink to connect our Aqua Purr cat water fountain. The push on quarter inch connector was easy to use, and I dislike plumbing. I like the added shutoff valve in case something goes wrong. Would definitely recommend

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

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

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.

Wish it has turning tight, but everything is good.

I used this product to my undersink water filter. I particularly like the shutoff valve that will make it easier to change the filter cartridge without turning off the main supply.

Thank you for selling this part! I was trying to install a under sink water filter and it came with 1/2 by 1/2 x 1/4 adapter, didnt work with my 3/8 fittings at all! I kept getting leaks. This solved every leak problem and made installation so simple. Best buy ever!

easier to install than the original that came with my RO system and works and fits better.
