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

Easy to install. Ive got a good stream of water again.

Thankfully had water sensor under kitchen sink. Discovered that this part (about 20yrs old kitchen faucet) was spraying water. Found it on Amazon at great price - nowhere else had in stock. Ordered Friday night and was delivered Sunday afternoon. Saved probably $400 versus plumber visit. One note -when i initially removed this part, i had to slide down yellow lock part, and then really pull hard to yank it off the faucet part. And on install, quickconnect needs to be held down with one hand while pushed up hard with other hand to lock onto the metal part that comes down from the faucet. My first replacement attempt it leaked since it had not snapped into place. Hard to get leverage under sink to do this. I should have know it wasnt snapped since it went in too easy. Needs some force - listen and feel for that satisfying snap.

This is a direct replacement coupling for my Grohe kitchen faucet. No problem since installation.

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.

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

There were no problems, replaced original before it failed after 8 years of use. Part fit right in, plumber just charged me for the time involved- no parts cost

a bit expensive, but worked great. took 3 seconds to replace the broken one.

Easy to install

Expensive but if you need it watcha gonna do.....Im just thankful it was delivered the next day...exacly the same as the original.

Our sink hose developed a leak on Christmas eve. I determined it was the Grohe quick coupling. It was easy to replace the coupling once I received the part several days later and I saved having a service call. Most anyone could replace this part.
