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

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.

Easy to use and a big improvement for the original connections

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..

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.

Grohe direct charges about the same $30 for this little part - so its not Amazons fault

Great buy!

Part is fine and installs easily. Just wanted to mention that Grohe refused to honor the lifetime warranty they claim for the faucet and parts. They claim normal wear and tear even though the part is stationary and shouldnt have wear and tear. Several reviews and questions indicate that the part seems to have issues with some people wanting a metal part instead of plastic. The new part I received from Amazon is slightly shorter, apparently a redesign by Grohe to reduce part breakage. The redesign has no effect on installation or function and works great.

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

Please take note, a loose fitting on the pull-down sprayer will mimic the symptoms of a bad quick-connect fitting. My experience matched exactly the description of several of the people who replaced the faulty part, but when I installed the new fitting the problem persisted. My wife was turning the water on and off while I was under the sink trying to sort out the un-fixed problem when she mentioned water coming out between the pull-down sprayer and the external faucet tube. A quick check showed that the sprayer head connection was loose and water was flowing back up and over through the external faucet tube and draining out under the sink. With low water flow, not a problem, but when the water was turned on full, water again drained out under the sink. This isnt to say that the quick disconnect fittings dont go bad and need replacing, but just a caveat to check the connection on the sprayer head as part of the diagnosis. An NTSB investigator would say that my mistake was applying seemingly accurate anecdotal evidence. ie my leak story exactly matched everyone elses, to reach an erroneous conclusion without also looking for other factors that could cause the same fault. Learn from my mistake.

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.
