## Customer Reviews

### ⭐⭐⭐⭐⭐ No leaks when you’re connecting it to a water filter tubing.
*by M***X on April 19, 2025*

So far, so good! No leaks! Perfect attachment to go with a 3/8 tee stop valve for my water filter.

### ⭐⭐⭐⭐⭐ Great fitting
*by F***Z on May 2, 2025*

Easy to install, works great and no leaks

### ⭐⭐⭐⭐⭐ Finally found what I needed!!
*by H***Y on April 19, 2024*

After multiple trips to the local hardware stores, I finally found what I actually needed on Amazon. I recently moved into a new house and had an RO installed the day after we moved in. I needed to hook up my RO to my refrigerator water supply line and was having no luck whatsoever finding the hardware to get it done. My RO is the APEC RO-HI (purchased from Amazon) with the 3/8" tubing for faster water dispensing. On new house builds (at least in AZ) the builder is installing 3 standard water valves under the kitchen sink area. 1 = hot, 2 = cold, 3 = refrigerator water line feed. By default the builder will use a 3/8" to 3/8" compression hose to connect valve 2 (cold water) to valve 3 (fridge water feed). I tried finding the standard tube compression fittings with nut & ferrule but I just couldn't seem to find the right part. I finally searched Amazon and found this 3/8" female compression to quick connect push-in tubing connector and it was exactly what I needed. The connector screws onto the standard 3/8" compression male adapter of a water valve and the other end accepts my 3/8" RO water line tubing. From the attached picture, you can see the connection to valve 3 (fridge water supply feed) on the right. This connector is attached directly to the water valve. You can't see it, but I cut a small piece of tubing and attached this connector to a 90 degree connector to eliminate extra strain heading up to the additional T connector on the clear tubing. The clear tubing is the filtered RO line going to my RO faucet. By adding the T connector, I have good water going to the RO faucet and into valve #3, which feeds my fridge water source. I added some Teflon tape to the valve 3 male end and hand-tightened this connector. No leaks and perfect result. Highly recommend this product if you need to connect your 3/8" RO tubing to your standard 3/8" compression male valve. A++
