Delta Kitchen Faucet Hose Replacement: Pull-Down or Pull-Out

Quick answer from a licensed plumber: Two Delta spray hoses to know are the RP50390 (“Quick Connect Hose & Clip – 54″ – Pull-Up / Pull-Down DST Faucets”) and the RP44647 (“Hose Assembly – Pull-Out,” 59 inches). The clip tells you which family you have: the RP60911 holds the RP50390, the RP32522 is the non-DST clip. On an older faucet the new quick-connect hose will not pass the sink-top support tube, so Delta pairs it with the RP31612 or RP6015SS support assembly. Delta does not sell a longer hose.

The clip most people need: Delta RP60911 quick-connect hose clip — the listing says “Clip for RP50390 hose Assembly” (Amazon-sold on September 25, 2026).

Step 1: DST or Not, Pull-Out or Pull-Down

Delta does not publish a hose chart the way Moen does; it publishes part pages and support answers, and the part titles carry the identification. Two current hose assemblies show how the titles work: the RP50390, which Delta titles “Quick Connect Hose & Clip – 54″ – Pull-Up / Pull-Down DST Faucets” (overall height listed as 54), and the RP44647, titled “Hose Assembly – Pull-Out” (overall height 59). DST is Delta’s “DIAMOND™ Seal Technology” suffix; a faucet model carrying the -DST suffix has Delta’s Diamond Seal valve, and the RP50390 is the hose Delta pairs with it.

Finding the model number is the fastest confirmation. Delta: “For most sink faucets made since 2012, the model tag is attached to one of the faucet supply lines.” With the number, Delta’s parts diagram lists the hose. Without it, Delta says: “If you cannot find your model number on the packaging, product, or instructions, use the online Product Identifier Tool. Go to the Service & Parts page and scroll to the Product Identifier Tool.”

RP31612 / RP6015SS	“a new support assembly that has been enlarged to accommodate the new QC fittings”	—	The sink-top tube a new quick-connect hose passes through

Step 2: Identify the Clip, Because the Clip Identifies the Hose

Delta’s support page on removing the hose says “Your pull-out or pull-down sprayer hose clip is likely one of these two,” the RP32522 or the RP60911, and the RP60911 is the one the Delta RP60911 listing ties to the RP50390. The clip changed without changing number: “Pullout hose clip RP60911 changed in shape and color in the latter half of 2014. They are interchangeable but the old black clip was not available after 2014.” It went black again briefly: “The clip temporarily changed color to black due to a national plastic resin shortage April-June 2021. The shape stayed the same.” So an old black clip and the newer clip of a different shape and color are the same part.

Removing either clip is a two-hand job without tools. Delta for the RP32522: “Grasp the clip with fingers or pliers and pull directly away from the fitting. It may help to grasp the hose with the other hand near the fitting and press the arms of the clip with your thumb. There’s no need to spread the arms.” The RP60911 clip comes off much the same way, by hand: Delta says to grasp the clip with your fingers and pull it straight off while holding the hose near the fitting on the opposite side, pressing the clip’s bars with your thumb toward your direction of pull. There is no need to spread them. Then, both: “With the clip removed, pull down on the hose.”

Delta-branded parts that were Amazon-sold on September 25, 2026: Delta RP60911 quick-connect hose clip (listing: “Clip for RP50390 hose Assembly”), the Delta quick-connect clip for non-DST pull-out and pull-down faucets (the listing Amazon returns for RP32522; its title prints no part number, so check the bag) and the Delta RP31612 support assembly (listed by Amazon under Replacement Hose/Spray). The RP44647 hose listing showed only a few units left that day and no Delta-branded RP50390 listing surfaced (only look-alikes from other sellers), so neither hose is linked; Delta’s part pages are in the sources.

Step 3: Check the Support Tube Before You Order

The most common surprise on an older faucet is that the new hose will not pass through the sink. Delta’s answer: “The old support assembly is not large enough for the Quick Connect to pass through. Along with a new Quick Connect hose, you will need a new support assembly that has been enlarged to accommodate the new QC fittings. The new part number for that is RP31612 or RP6015SS .” If your faucet predates the quick-connect hose, plan on both parts.

Getting the Old Hose Off

Delta describes two other quick-connect fitting styles and the release for each: “Pinch together at the base of the black or grey plastic halves, next to the hose. The top halves will spread apart, opening the tabs on the brass connector. It may help to push up on the fitting if the tabs are not releasing.” Or, on the square-tab type: “Pinch together at the ridged, square tabs on the sides of the fitting.” Delta adds that pushing up on the fitting may help if the tabs are not compressing, and warns: “Do not pull the tabs out as that may lock the hose to the tube.” Then “Pull down gently to remove the quick connect hose.”

First: Turn the water off first and confirm it is off before you loosen anything. If a shutoff valve will not close, or a pipe or fitting is cracked, stop and call a licensed plumber. Delta: “Turn the faucet off” before pulling a clip, and keep a towel and a light under the cabinet; the hose holds water.

Two Things Delta Will Not Sell You

A longer hose, for one. Delta: “Unfortunately, Delta Faucet Company does not offer a longer alternate vegetable sprayer hose, or widespread valve connection hose.” And a hose is not always the fix for a wand that stops short: “The hose for the pull-out faucet is flexible. Grab a flashlight and buddy. Find what the hose is catching on underneath the sink, or if the hose is twisting on itself.” Check for a twisted hose or a weight snagging on the supply lines before ordering anything.

FAQ

Which hose fits my Delta pull-down kitchen faucet?

For a DST pull-up or pull-down faucet, Delta’s RP50390 quick connect hose and clip (54 inches), held by the RP60911 clip. Pull-out faucets use the RP44647 hose assembly (59 inches). Confirm with the model tag on a supply line or Delta’s Product Identifier Tool.

What is the Delta RP60911 clip for?

It is the quick-connect hose clip for the RP50390 hose. Delta changed its shape and color in late 2014 and briefly made it black again in 2021, but says the versions are interchangeable.

Why will the new Delta hose not fit through my faucet?

The old support assembly through the sink top is too small for the quick-connect fitting. Delta says to replace it with the RP31612 or RP6015SS support assembly along with the new hose.

Can I get a longer Delta sprayer hose?

No. Delta says it does not offer a longer alternate vegetable sprayer hose or widespread valve connection hose.

How do I take the clip off a Delta pull-down hose?

Turn the faucet off, then grasp the clip and pull it straight away from the fitting while pressing its arms or bars with your thumb; Delta says there is no need to spread them. With the clip off, pull down on the hose.

Bottom Line

Read the model tag on the supply line, then match: DST pull-up/pull-down gets the RP50390 hose with the RP60911 clip; pull-out gets the RP44647; non-DST clips are the RP32522. Order the RP31612 support assembly with the hose if the faucet predates quick connects, and check for a twisted hose before blaming the hose.
