Hi Eric, Thank you for your question. The RP50390 is the pull out hose assembly for our Diamond Seal Technology (DST) pull out and pull down faucets. The RP44647 is the pull out hose assembly for our non-DST pull out and pull down kitchen faucets. The end that connects to the faucet on each model is different. Thanks, Dave
I am unable to connect the Delta RP44647 replacement hose on to my valve shaft. I have provided a photo showing the original hose compared to the replacement hose RP44647 along with a picture of the valve shaft. As you can see the original hose has a silicon rubber insert which fits over the valve shaft perfectly. The RP44647 does not have this design. Please provide instruction on how to attach RP44647 to my valve shaft. Thank you.
Hi Del, Thank you for your question. Based on your photographs when you removed the old hose, the hose itself separated from the fitting that attaches to the faucet. The old fitting is still attached to the faucet shank. Once you remove that piece the new hose should hook up to the shank properly. Thanks, Dave
Thanks Dave! That was it! I just used a pair of needle nose pliers and pulled right off the brass fitting and new replacement hose attached to the valve shaft very easily. I greatly appreciate Delta's fast response and excellent support!

Installation of RP44647 hose assembly
Experiencing the same problem that Greg has stated. The newly designed coupling is too long to make the tight radius curve of the faucet. Turning the faucet holder either to the right or left DOES NOT work.
Can the hose be cut and reassembled with an inserted tube and band clamps? Anything to get this blasted thing to work !!!
Hi Cheryl, Thank you for your question. When you get to the point where the hose is getting hung up try twisting the hose while applying pressure to help guide the hose through the opening. Thanks, Dave
I received the RP44647 to replace the original hose that was leaking. I was unable to pull the old hose through the faucet after disconnecting it from the valve shank and the spray head without cutting the old hose.
Now I am unable to feed the new hose through the faucet without getting hung up on the two copper intake tubes!
Hi Greg, Thank you for your question. We are sorry that you are experiencing difficulties with your faucet. We suggest that you move your spout 90 degrees to the left or right to facilitate threading the new hose through the hub of the faucet. Thanks, Dave
We replaced a split original hose for a Delta pullout kitchen faucet with RP44647, but the hose end with clip properly in place won't push onto the valve shank. Should it be this difficult? It seems to require more force than we can give it. I am cursing the designer. What suggestions do you have?
We apologize that you had a problem installing your hose and that the directions we confusing. I will relay this to our team to see that it gets fixed for the future. Glad you got it working and thank you for posting the fix for others to see in the meantime.
Question answered by the plumbing supply store that sold us the hose. Yay! When you pull off the hose, a brass insert remains on the valve connect and needs to be pulled off. Place the new O-ring on the revealed connect, and the hose goes right on. This essential piece of information is missing from the instructions provided with the replacement hose.

how do I remove the hose assembly quick connection under the sink ?
I am sorry to hear about the trouble that you are having with this hose.
To remove the hose from the connection under the sink, grasp the spine side of the clip and pull away from the hose/connection. Once this clip has been removed, the hose will pull off the copper line with very little force.
Hi - Can you take a look at the two pictures attached, I need to get a new hose for my delta faucet but I do not know what the model number is. The hose is CHROME and has a clip, quick -connect assembly. I can only seem to find vinyl replacements. Can you let me know what the model number of my faucet is and what model number the replacement hose it. Thank you very much.
Will the rp44647 work on my faucet. (photo included) A local dealer said the hose I have is rp32527. The delta operator said it will work when I called to order the part. A question asked on this page says it won't. Can you help me please. The hose is on it's way (rp44647) will it work.
Thank you for your question. The model for your home should be on your paperwork for your faucet. At that time, we were not including model numbers on the faucets themselves. If you do not have your paperwork, you may send a picture of your faucet to our Home Owner/Warranty line at firstname.lastname@example.org.
