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

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

Easy to use and a big improvement for the original connections

My taste in faucets is ridiculous. I seem to like the really expensive ones! When this part of the faucet broke, I was looking at an expensive replacement. Luckily, this part was available and delivered on time. Faucet is fixed! Thanks Amazon.

Real simple tool-free install. Only challenge is getting access to coupling location on faucet after the faucet is installed. The coupling is located behind sink directly below counter top. The quick coupling part (1.75 liter/min) that comes installed on faucet directly from factory is so restrictive of water flow that we couldnt even get the spray to stay on. Apparently Grohe ships faucets to the U.S. that meet some sort of flow restriction standard. I read one place that the standard is called California Green, which I can only assumes comes from the droughts CA has been experiencing in recent times. In any event the Groho 46 138 000 Quick Coupling part has no flow restriction. So now our faucet works perfectly. Only drawback is the part is priced ridiculously high. $40+ dollars for a small plastic part is absurd. The term that comes to mind is price gouging. Having said that, it works perfectly and completely solved our low water pressure problem.

For something plastic it sure is overpriced. But what else can you use as a replacement? Got mine just in case and when i changed the hose found out that my old connector was cracked although it was leaking.

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.

not like back in the day, easy peazie lemon squeezee. i thought it was going to be a nightmare, i did not know anything about the sink in the new house. when this happened can of worms piped into my head. nope , put on the new hose i ordered for the faucet , click done.

Worked out very well and is holding up fine.

Fixed our flow issue with our Grohe faucet. The original flow restricted coupler clogged up in 18 months with our hard water. This one restored the pressure back to better than new. Not happy that I had to swap the part out, but happy with this little connector. Super easy to replace.

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.
