Grohe 46138000 1/2 in. Quick Coupling, one-size

It was easy to install and, so far, its working fine.

If your leaking under the kitchen sink, it’s probably this weak leak. Easy to install. Not sure why they make this important part in plastic.

While Grohe manufactures a good product this was manufactured with planned obsolescence in mind….give it 2, 3 or 4 years and it tends to crack at first causing a fine spray…eventually it will break !! It is difficult to find locally and it usually costs more than Amazon Prime !!

I liked it

Youll know when you need a new one. When you do, this product makes solving the problem very easy. Installation was as described and straightforward. Be certain to shop around -- Grohe parts are not as readily available as other brands -- and if you do so, you can save a considerable amount of money.

Being able to get this part saved us a lot of money.

hand installation, no tools needed

I probably did not need to replace the original but it was 18 years old and since I was replacing the hose I felt that it was no big deal, works seemlessly with new hose

Easy to install and no leaks!!

Replaced my RED connector (that wasnt leaking) with this because of low flow that I tried to solve many other ways (new spray head, cleaning the red connector several times, backing out the flow screw in the handle) but this solved it in minutes. You have to screw it onto the hose end and then hold down the yellow snap section and get it ALL the way over the pipe from the faucet under the sink. It must snap back over the pipe securely or it will pop off when you turn the water back on and then try the faucet. If it pops off you did not get it all the way on and snapped tight.
