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

I’ve been experiencing water pressure and flow issues with my Alira faucet. First I replaced the cartridge. That didn’t fix the issue. Next I flushed the water lines. That didn’t fix it. Finally I replaced the yellow quick coupling. That did the trick. I have strong water pressure again. Super easy to install. Glad I was able to find this part on Amazon.

Installed without difficulty . Thank you!!

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

This a ingenious connector for using under the sink. However this is the third one that I have had to buy. I just wish they would have made it stronger because it can be easily broken if you hit it with something under the sink, like changing the garbage disposal or have some pull the sprayer out too far.

Replaced my RED connector (that wasnt leaking) with this because of low flow that I tried to solve many other ways (new spray head, cleaning the red connector several times, backing out the flow screw in the handle) but this solved it in minutes. You have to screw it onto the hose end and then hold down the yellow snap section and get it ALL the way over the pipe from the faucet under the sink. It must snap back over the pipe securely or it will pop off when you turn the water back on and then try the faucet. If it pops off you did not get it all the way on and snapped tight.

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.

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

easy to install, but be cautious because the plastic threads will crack if you try to put it on too tight. For that reason and the high cost is why I did not rate this product five stars.

This coupling replaced one that failed a while back, but I should have first read the reviews and purchased the green one, which is allegedly built better.
