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

No tools necessary...replaced in just a couple of minutes

Threaded on just fine. Snapped into place without issue. No more leaks! (I used this to replace my slightly older green coupling)

This worked fine and less than half I would have paid at my plumbing supply company.

Great buy!

Item is really wimpy compared to the original but it went on easy and most of it doesn’t leak and I got the item the next day through amazon and didn’t have to run around trying to find the right part. Thank you

Lifesaver- stopped leak & avoided me having to put a whole new faucet in. Old part went bad after 5 yrs. Home Depot & Lowes does not sell this item. No plumber needed to install.

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

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.

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.

Installed without difficulty . Thank you!!
