Delta Faucet RP50390 Quick-Connect Hose for DIAMOND Seal Technology Models

I was concerned it wouldn’t work because this replacement hose is shorter than the original, but the original was frayed so much it was leaking a good amount so I went for it! Adjusted the other cords, etc under the sink so the hose could move a little easier with less room. I can’t pull the hose out as far as I could before and occasionally it feels like it got caught on something, but it’s not a problem and easy to adjust to!

I'm pretty handy for a girl and I refuse to hire a plumber unless there's an issue with an appliance that uses gas...The installation was easy...I have the Delta Uptown: Kitchen Pull-Out Faucet. The original hose started leaking right behind where it's attached to the handle. I've had the faucet for many years, so just having to replace the hose was no big deal. As much as I would like to redecorate with a new faucet, it just isn't economical for me right now. First, this replacement hose is a bit thinner then the hose that came with the faucet, but it is actually easier to maneuver and it's lighter too. So I would say I prefer it over the original. It's only a few inches shorter then the original, so I just moved the weight/stopper up a little and I get the same amount of hose.Tips....I had to pull out the old hose from the faucet end because it won't fit through the hole pulling it from under the cabinet. I had a weight/stopper on the old hose which I used on the replacement since it didn't come with one. The weight is 2 pieces that has a screw on each side to close it onto the hose. It was a tad big on the new hose, and I was afraid it may slide a little which would defeat the purpose. So I just put a few rounds of electrical tape on the hose and that seems to hold it in place just fine once I clamped it on. Lastly, it does come with a clip for the quick-connect end, but it didn't fit over the metal pipe (too small I think), so I used the old clip which seems to work fine. You will need this piece since it keeps the quick-connect end from coming loose.So the hose only comes with a clip and some white plastic cap looking thing which I have no idea what it was for, but there should be no reason you can't use your existing parts for this hose.Edit: 2/22/13The quick connect end finally came off. Not because of a faulty product, but because I used my old clip to hold it on and i was too big I think. I got under the sink and finally was able to snap on the black clip that the hose came with. It's a much tighter fit, but I think that's what you would want. So if it seems like it doesn't want to go around the pipe and hose easily, use a little more force until it snaps over them. It will be worth the effort.

This is the second hose I purchased to replace the damaged hose on our Delta kitchen faucet. The first one fit fine on the nozzle, but not on the under sink attachment. Make sure to check both connections. If your nozzle connection is castleatted and you have a blue clip around a PLASTIC connector under the sink then this hose is for you. If you have a black clip with a brass (metal) connector under the sink you will need a different hose.If you have problems getting this threaded through the faucet with the little helper 'cap' they supply then you can try an alternate approach: A large novelty pencil. Feed the sharpened end of the pencil up into the faucet from the bottom, then feed the plastic cup end of the new hose through the top of the faucet. The cup will catch on the point of the novelty pencil which will center it in the hole. Once you feel the hose end on the pencil tip keep pushing on the hose as you draw the pencil back out and the hose connection should follow smoothly through. You could accomplish the same thing with a properly sized piece of dowel rod sharpened to a cone on top. This worked much better for me than the plastic 'cap', which didn't help at all.

I purchased this hose to replace the original hose on our Delta pull-down faucet. (The older hose and faucet are probably 5-6 years old.) We were getting black debris in our water from this faucet. The new hose was easy to replace once I realized that the small white rounded plug which came with the new hose needed to be used to thread the new hose through the faucet. There were no instructions about doing this with the new hose and plug. I had to go to he Delta website to see a parts breakdown for the faucet to notice that this temporary plug was needed to get the hose to pass freely through the metal faucet. (I spent about an hour trying to thread the new hose through before resorting to an exploded view of the faucet assembly and realizing the rounded plug was necessary.)I disected the old hose and found serious deterioration of the inside of the black rubber that is in the woven silver jacketing - explaining the black particles we were noticing the dispensed water. Looks like a poor material choice or bad compounding of the rubber by Delta (as a retired polymer engineer). Typically neoprene or other chlorine-resistant elastomers would be used in city water applications. Hopefully that has been corrected with the replacement hose.

Working so far, even though the length of hose is shorter than stated and the original hose that came with my faucet. The connectors on mine appeared to be damaged but still works.

Easy purchase & easy install

Perfect replacement. Installed about 4 months ago and so far so good. No leaks and wife has complained about kinking so all good

Good product

Even though this is the correct part # for my faucet from Delta, the end that goes on the pipe under the sink doesn't fit and leaks. I fixed this by taking a piece of rubber from the old hose connector and wrapping it with electrical tape to fit snugly in the new hose end that pushes on. A little bit of vegetable oil on the pipe coming down from the faucet and it slid in place and clip is installed. No leaks!Really fast shipping, no complaints on that.
