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

easy to put in place

It was a perfect fit for my Grohe lady lux kitchen faucet.

This is the link you need for the hose to connect to the facuet. Easy to install and just need to hear the click when you install it and you are done.

Not constructed as well as the original part installed in 2004,but it worked and I no longer have a flood of water under my kitchen sink. I believe this part is too expensive, but it is a Grohe part, what can I say..

This was probably the easiest plumbing project I have done. Removal and replacement was effortless.

Product worked perfectly! In the beginning I wasnt too sure if it would work to replace the original one, but I went for it since it came paired up with the 46092000 Kitchen Faucet Hose. Easy install, no leak, extremely satisfied! Only thing is that these parts are costly but once there is no leak, its like what money!

We had a small leak as the existing coupler developed a crack. It was good to know that one size fits all Grohe Faucets. Very easy to remove old one and install new.

Easy fix

I you are suffering from low flow in your Grohe faucet, this item is the fix! Though my newly-installed Grohe Zedra triple-spray pulldown faucet was put in by a licensed plumber - and we cleaned debris out of both the quick connect and the spray head - I was only getting about 1 gallon per minute or less....not even enough pressure to activate the shower spray option. I put this new quick coupling in last night in 30 seconds, and the spray/water volume improved INSTANTLY. We are now very happy with the faucet. Before this fix, we were so disappointed in the faucet performance as it came from the factory that we considered removing the faucet and throwing it away! So. Happy. Now.

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.
