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

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.

Easy to install

When we received it, the size appeared different than the one that was broken (we held them side by side) but it still fit! Just needed to tap it on with a rubber mallet because it wouldn’t go on at first.

OK we have a Grohe faucet and for years my husband has had to take it apart to clean it out (under the sink). Usually every week or two. A real pain. So finally he decided to see if this would help. What a difference. Every once and a while he has to remove the top of the faucet which just screws on and rinse out the accumulation. This takes just a few seconds and done. Mean while I have the best flow of water in over ten years. Must add here that we are on a well so we have tiny bits of stuff that make it through the filter. Will add our water taste the best. No chlorine so we are drinking water that taste like a swimming poo. This arrived fast and was the best price out there.

Quality

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

It fits. I hope the new plastic screw in part lasts. The old one disintegrated and the tubing fell off.

Replaced the broken piece perfectly.

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

excellent description. good quality. fast delivery.
