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

This is the link you need for the hose to connect to the facuet. Easy to install and just need to hear the click when you install it and you are done.

When you need to replace one of these babies, you REALLY need it! This is the second one Ive purchased within the past year since these things seem to crack over time and need to be replaced, especially when changing out faucets. It came very quickly and works great.

It was easy to install. The old one was the green one. I read that the yellow one was a bit better, so I purchased it. It went on well. super easy.

I was doing the dishes the other night using our 8-year-old Ladyluxe faucet when I noticed my foot was wet. I looked down to find a small torrent of water pouring out from under the cabinet door. I thought the drain had come loose or the disposal was leaking. But, it was this plastic part at the base of the faucet. The threaded, black side split and a thin stream of water was shooting all over the cabinet interior. The part was easy to unscrew and identify as Grohe part 46 315 but I found this part, Grohe 46 138 that looked the same and was eligible for Amazon Prime. I took a chance and ordered the part and installed it without a hitch. It seems that 46 315 and 46 138 are equivalent replacements for each other. I did notice a little difference internally; the shape of the internal screen is a cone shape where the newer 48 138 is flat. This might just be an update to all their parts, though. In the end, the 48 138 fit and works. On the subject of the actual Grohe part, I seems this part is a common failure point in this design. It didnt take long to find talk on discussion boards about this part failing after 5 years. Im going to buy a spare and leave it in the cabinet so I dont go through this in another 5-8 years. I doubt Id buy another Grohe faucet after this experience, though.

Same as original equipment

Expensive but if you need it watcha gonna do.....Im just thankful it was delivered the next day...exacly the same as the original.

A great idea, but a little pricey. If I have to change the fawcet hose on the sink every 15 or 20 years, the convenience isnt all that important.

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

Liked It

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.
