Replacement Hose for Pull-Down Kitchen Faucet: How to Tell Which Fits

You have a pull-down kitchen faucet that won’t retract, drips under the sink, or has a cracked hose, and the shelf at the hardware store is full of hoses that all look right. Most of them aren’t. The replacement hose for pull-down kitchen faucet models you own is usually identified by the faucet’s model and by the two connectors on the hose, not by its length. This page walks through how to read both, then how to confirm with the manufacturer’s parts diagram before you order.

Method 1: Find the Model Number on the Faucet and Under the Sink

Start under the sink. Delta’s support PDF says faucets made after 2015 should have a model identification tag on the supply line. Kohler says the faucet model number is printed on a tag attached to the cold water supply line below the sink or countertop, and that it is commonly preceded by “P/N” (Delta, Kohler).

If the tag is gone, look for the original paperwork. Moen says exact model numbers can be found on the box or instruction sheet. Kohler says model numbers may also appear on the box label, product literature, invoice or receipt, or be stamped directly on the product (Moen, Kohler).

Markings on the faucet itself help, but rarely finish the job. Moen says its name may be on the faucet, some kitchen faucets have a number on the back of the spout, and some handle caps are imprinted with “Moen” (Moen). Pfister says its model numbers are usually eight-character codes such as F-529-7AYY, shown on the package and instruction manual below the product name (Pfister).

One trap: don’t mistake a standards marking for a model number. Moen says “A112.18.1” may appear on the spout, aerator, or spray wand, but it is a plumbing standard marking, not a faucet model (Moen).

Method 2: Compare Both Hose Ends

The hose is itself an identification surface. Moen’s retractable-hose guide says hose material, length, and connection type have changed over time, that some models used more than one hose, and that you should compare the connection at both the spray wand and the faucet body before ordering (Moen). Length alone won’t tell you what you have.

That same guide documents Moen’s major connection generations, listed in the chart below. It pairs them with photos of the connector styles, including black quick-connects with white release tabs and white quick-connects with black release buttons. Those can look alike at a glance, so hold the old hose next to the photos rather than judging from memory.

Before you disconnect anything, photograph the full under-sink assembly: the hose weight, the quick-connect, the spray-head connection, any supply-line tags, and any solenoid or battery box on an electronic faucet. Those photos are what you will send to a manufacturer if the model turns out to be unreadable.

Replacement Hose for Pull-Down Kitchen Faucet: The Chart

Use this table to narrow the field. It tells you where each brand puts its model information and what the brand itself says about hoses. It is not a compatibility list: in every row, the parts diagram for your exact model has the final word.

Brand	Where the model shows up	What the manufacturer says about the hose	Confirm it here
Moen	Box or instruction sheet; sometimes the back of the spout or the handle cap	Connector generations: threaded (1991-2003), single quick-connect (2003-2007), double quick-connect (2007-2010), built-in quick-connect (2010 to present), T quick-connect (2022 to present). Some models used more than one hose.	Moen’s exploded parts view, or Faucet Finder photo upload
Delta	Tag on the supply line (faucets made after 2015)	Lists RP50390 (54 inches) and RP62057 (62 inches) as hoses for pull-up/pull-down DST faucets, with RP60911 as the hose clip. Delta’s own RP44647 page describes RP44647 as a braided vinyl hose for non-DST pull-out and pull-down faucets.	Delta’s “Find Parts and Identify Your Product” page
Kohler	Tag on the cold supply line, commonly marked “P/N”	Model numbers carry finish codes (such as CP) and generation letters (such as AA, AB, AC, BA)	Kohler’s service parts page; Kohler Scout photo ID
Pfister	Package and manual; eight-character codes such as F-529-7AYY	Parts diagram per model; 951-0740 is an official pull-down hose, limited to models that list it	Pfister’s parts support pages
American Standard	Product page and repair parts list	Model-specific: the Aspirations touchless faucet lists a spray hose assembly (M970804-0000A) and a quick coupling (M970803-0070A) as separate parts	The product page’s spare parts list

The Delta caution

Delta’s pages show why you can’t memorize a rule. Delta’s Q&A page for RP44647 also gives a field clue: DST models generally have gray PEX/plastic supply lines, while non-DST models generally have copper tubing. But the same pages list RP74608 as the hose assembly for at least one DST model (470-WH-DST) and say RP50390 and RP32527 are not interchangeable (Delta RP44647, Delta RP50390). So “DST means RP50390 or RP62057” is a starting point, not a rule.

Length is unreliable too. Delta’s common hose page lists RP50390 as 54 inches, while some retailer copy for the same part lists a 52-inch hose (Home Depot, Lowe’s). Treat the manufacturer’s page as the specification and the retailer’s as a price and availability check.

Why a Serial Number Won’t Pick the Hose

Readers often expect a serial-number decoder. For pull-down hoses there isn’t a public one. We found no manufacturer source that uses a homeowner-readable serial format to select a pull-down kitchen faucet hose; Delta, Moen, Pfister, Kohler, American Standard, and Hansgrohe all point you to model identification and parts documentation instead.

Kohler does publish structure. Its serial numbers are usually 8 to 11 characters, most commonly 9, often start with “S,” and contain no dashes or hyphens (Kohler). But Kohler’s faucet guidance centers on finding the model number, which is what you actually need for the hose.

Dates matter only when a manufacturer’s part page says so. According to Hansgrohe’s page for hose 88624000, compatibility for some faucets is split by production window, such as 01/17-05/21 versus later than 06/21 (Hansgrohe). That is why the same model name and finish may still not be enough. For Delta electronic faucets, the support PDF mentions a six-digit date and version number on the solenoid assembly label. Moen’s retractable-hose guide lists the years each connector type was used, shown in the chart above (Moen). Reading those year ranges as a rough date clue is our inference, not something the guide says.

Look Up the Part Before You Buy

Manufacturer tools come first. Delta accepts a known model number or walks you through a guided product identifier to a page with parts and diagrams, and says older models may not be on the site, in which case you can call 1-800-345-DELTA or email support (Delta, Delta FAQ). Moen says the exploded parts view on a product page is the best path once the model is known (Moen).

Kohler offers a service parts page and Kohler Scout, which lets you snap or upload a photo to find the model number (Kohler, Scout). Pfister tells you to browse the matching kitchen pull-down or pull-out category, turn on “show discontinued” for older faucets, pick the matching faucet, and open its parts diagram (Pfister).

A few part-number details show why the diagram matters:

• According to Moen’s guide, 150259 and 202750 are interchangeable packaging variants of one 68-inch built-in quick-connect hose, yet it also lists look-alike numbers such as 150259B, 207071, and 212650 that are model-specific.
• Moen also separates underdeck hoses for separate-handle faucets from the retractable hose used by pull-down sprays, and says several versions are not interchangeable.
• American Standard says M920529-0020A is compatible with its Porcini pull-down faucet, a separate part from the Aspirations hose.

Retailers such as Home Depot and Lowe’s are useful to confirm availability and price once you hold a part number. They should not override the manufacturer’s diagram. Retailer sprayer categories can also mix commercial-style hoses in with residential ones, so don’t match on “looks like a braided hose.”

If You Still Cannot Tell

When the brand is unknown, document first. Photograph the whole faucet, handle side, spout shape, the underside of the spray head, the hose-to-wand coupling, and the under-sink connection. Moen says its Faucet Finder lets you upload a picture of the faucet to identify the model number and collection name, and Pfister says you can send its support team a photo of your faucet and that it can usually answer within 24 hours (Moen, Pfister).

Be careful with “universal” parts. A universal spray head is not a universal hose. Danco’s Smart Spray is a pull-down replacement spray head with adapters for several brands, not an under-sink hose (Danco). Danco’s 10912 hose kit includes multiple base adapters but says it fits pull-out sprayer heads and does not fit pull-down spray heads or side sprayer heads (Danco). Universal parts may help with spray heads or some pull-out repairs; for a pull-down faucet, treat the hose as brand-, model-, and connector-specific.

Family Handyman says some spray heads and hoses connect differently and that home centers and hardware stores usually carry only a standard type (Family Handyman). Bringing the old hose and spray head to a plumbing supply counter is a reasonable last step, as a fallback and not proof that a generic hose will fit.

If photo ID and manufacturer support both fail, replacing the whole faucet may be more practical than chasing an unknown proprietary hose. That is our inference, not a manufacturer’s rule. This Old House advises choosing a known brand so replacement parts stay available later (This Old House). Our kitchen faucet replacement guide covers that route.

One more wrong-part lookalike: Kohler says improper hose weight placement can keep the sprayhead from seating back into the spout, and Moen’s instructions distinguish snap-on from non-snap-on hose weights (Kohler, Moen). Check the weight before you blame the hose.

When to Call a Plumber

Identifying the faucet is usually a homeowner job. Removing a stuck hose, or confirming a fit under a cramped sink, can become a plumber’s job. This Old House notes that limited under-sink space can make faucet work difficult and recommends checking shutoff valves and supply lines while you are under there (This Old House). Call sooner if you find corroded shutoffs, an inaccessible quick-connect, solenoid wiring or a battery box, or a hose that catches inside the faucet body. Delta’s Q&A notes a hose can catch on the faucet body or copper tubes and suggests rotating the spout or twisting the hose while feeding it (Delta).

Professional opinions vary on removal. Moen and Kohler each give a connector-specific sequence: Moen’s instructions for 150259, 202750, and 212650 start with shutting off water and removing the hose weight, while Kohler’s older hose-kit instructions use a different order and stress controlling the hose so it does not retract (Moen, Kohler). According to Delta, for RP50390 the hose should fit through the hub and spout, removing the spout may make it easier on some models, and cutting the hose is not recommended because it can void an applicable warranty (Delta).

Service-call pricing varies by source. HomeGuide lists plumbers at $45-$150 per hour and service call or flat fees of $50-$200. Housecall Pro says many residential plumbing businesses charge a $75-$150 service call fee, and Angi lists $100-$250 (HomeGuide, Housecall Pro, Angi). Read those as broad national planning ranges; a local minimum can land higher, and you should ask for the quote first. A paid visit can still cost less than repeated wrong hose orders if the model tag is missing or the connector is proprietary.

What to Do Next

Get the model number first, photograph both hose ends, and then confirm the hose on that model’s parts diagram. If the hose is only one symptom, our faucet repair hub covers the rest, and the faucet replacement parts glossary explains the terms you will see on a diagram.
