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

Worked great and saved my behind from buying a brand new faucet!!!

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.

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!

The grohe quick coupling fit was correct. I had used my original coupling twice but decided to purchase a new one. Im glad that I did. One word of caution: make sure when connecting back to your faucet, check for clearance between the three tubes. The coupling should snap on without much effort.

Same as original equipment

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.

Well built, stopped leak of my Ladylux faucet.

Replaced the broken piece perfectly.

30 year old original needed replacement

Factory part! Works perfect!
