American Standard Faucet Cartridge Identification: Find the Right Part Every Time [2026]

American standard faucet cartridge identification trips up more homeowners than almost any other brand — not because American Standard is complicated, but because the right workflow is different from what most DIYers expect. You can’t eyeball an American Standard cartridge and order a match by shape alone. American Standard ties each faucet model to a specific repair-parts diagram, and that diagram tells you the exact cartridge kit number. Skip that step and you’re likely to order the wrong part before getting the right one.

This guide walks you through three identification methods in order of reliability: find the model number and look up the repair-parts diagram; identify by fixture type and visible features; and use American Standard’s online tools as a backup. It covers bathroom sink, kitchen, and tub/shower valve types.

Method 1: Find the Model Number and Look Up the Repair-Parts Diagram

The most reliable American standard faucet cartridge identification workflow starts with the model number — not the cartridge shape, not the finish. American Standard product pages tie each model number to a spec sheet, installation guide, and repair-parts diagram, and that diagram names the exact cartridge kit.

Where to find the model number:

Start with paperwork. American Standard installation manuals list the covered model numbers on their first pages, so any retained owner’s manual, installer packet, or QR-code warranty sheet is the fastest win. The model format looks like 7426801.002 — the digits before the dot identify the faucet model family and the three digits after the dot identify the finish: 002 for polished chrome, 295 for brushed nickel, 243 for matte black.

If the paperwork is gone, check the underside of the sink or countertop. Installer labels, supply-line markings, and stickers applied during installation are often still there. Clean mineral deposits off mounting hardware before calling it a loss — stamps and codes hide under years of scale.

For a two-handle widespread lavatory faucet, check the separate valve bodies under each handle in addition to the spout shank. On widespread American Standard models in the 742X801 group, the repair-parts sheet calls out M964005-0070A as the cartridge kit — but you still need to confirm the model family before ordering, because that part number applies only within that specific model group.

Once you have the model number:

Go to AmericanStandard-us.com, search the model number, and open the product page. Product pages for models like the Belmeade (7426801.002) show the finish, spec sheet, installation guide, and repair-parts diagram in one place. Open the repair-parts diagram — it’s typically a PDF hosted on the Lixil CDN — and find the cartridge kit entry. The finish-code convention also appears in the parts sheet itself: it tells you to replace YYY with the appropriate code for your finish.

Method 2: Identify by Fixture Type and Visible Features

If the model number is gone, narrow the search by fixture category first. American Standard separates bathroom sink faucets, kitchen faucets, tub/shower faucets, and shower systems in both its product catalog and its parts store — so the fixture type alone cuts the search space significantly before any disassembly.

Bathroom sink faucets: Determine whether you have a single-hole, centerset, widespread, or vessel style. On widespread models, look for the T-connector under the spout and separate hot/cold valve bodies under each handle — that installation layout is documented in American Standard’s widespread lavatory installation guides and confirms you’re working with a two-valve system where cartridge identification depends on the valve body, not just the spout profile.

Look for collection names on the faucet body, escutcheon plate, or handle cap. American Standard catalog collections include Belmeade, Becklow, Aspirations, Studio S, Saybrook, and Edgemere, among others. Any of those visible marks maps directly back to a product page with a repair-parts diagram.

Kitchen faucets: Check whether the faucet is pull-out, pull-down, semi-pro, bar/prep, filtration, or touchless. American Standard separates kitchen faucet parts from bathroom faucet parts in its online parts store — kitchen and bathroom cartridges are not cross-compatible. If the faucet has a filtration unit or touchless sensor, record that feature before shopping, because those functions often require model-specific service kits not available at a general hardware store.

Tub and shower valves: The handle and trim plate may display the collection name, but the actual cartridge is determined by the valve body inside the wall — not the visible trim. In many cases you need to remove the handle to expose useful cartridge identification clues. Shut off water at the supply shutoffs before any handle removal, and think honestly about whether that step is within your comfort zone. If the answer is no, the identification is better handled by a plumber — a wrong shower cartridge can leave the shower unusable until the correct part arrives.

Method 3: Use American Standard’s Online Lookup Tools

When visible marks and paperwork aren’t enough, the manufacturer’s digital tools are the next stop.

American Standard parts store: Navigate to the bathroom faucet parts category or the kitchen faucet parts category and browse by fixture type and collection to find the closest match. Once you reach a product page, open the repair-parts diagram PDF to confirm the cartridge kit number. The weakness of this path — acknowledged in American Standard’s own product documentation — is that it works best when you already know the model or collection; it’s not as streamlined as Moen’s visual cartridge guides when you have only a bare cartridge in hand.

American Standard warranty registration: If the faucet was registered when installed, your account may carry the model number. American Standard’s installation guides include a warranty-registration prompt and note that registration keeps product information available for future service needs. Worth a quick check before tearing apart the sink.

Cross-brand photo and lookup tools: If you’re not certain the faucet is American Standard, Kohler’s KOHLER Scout accepts a photo upload to help identify a model — useful when the only visible mark is a worn logo. Delta’s product identifier narrows by room, product type, and fixture description. Moen’s Faucet Finder and bathroom cartridge visual guides identify cartridges by handle operation, retainer clip style, and cartridge color — a useful cross-check if a prior repair may have introduced a Moen cartridge into an American Standard valve body.

American Standard Faucet Cartridge Identification: Quick Decision Tree

Use this sequence when starting from scratch:

1. Check the paperwork first. Any manual, installer receipt, or warranty sheet? Search the model number on AmericanStandard-us.com and open the repair-parts diagram PDF.
2. Check under the sink. Installer tags, stamps on mounting hardware, supply-line labels. Clean mineral buildup before giving up on a stamped code.
3. Photograph everything before disassembly. Front, side, underside, handle shape, supply connections, and any visible numbers or marks. Once parts are out, those photos are your only reference.
4. Classify the fixture type. Bathroom sink (single-hole / centerset / widespread / vessel), kitchen (pull-down / pull-out / bar / touchless), tub/shower, or shower system. Navigate to the matching American Standard parts-store category.
5. Look for a collection name. Belmeade, Becklow, Aspirations, Studio S, Saybrook, Edgemere — any of these maps to a product page with a repair-parts diagram.
6. Use the parts store or contact American Standard support. If the collection is still unclear, browse category by category. If that fails, American Standard customer support can look up parts by fixture description and photos.
7. Confirm the model family before ordering. Similar-looking faucets may share a repair sheet only within a specific model group. The repair-parts diagram is the authoritative match — not the cartridge’s physical dimensions.

What to Do When You Can’t Identify the Cartridge

If every method above fails — no paperwork, no visible markings, and photos don’t match any catalog entry — here are your remaining options:

Remove the cartridge and bring it to a plumbing supply house. A plumbing counter can often match a cartridge by physical inspection. Bring the retainer, clip, and nut as well — those components tell as much as the cartridge body.

Use retailer category filters as a last resort. Home Depot’s faucet cartridge category lets you filter by brand and “fits faucet brand,” and shows OEM and DANCO aftermarket cartridges side by side. Aftermarket cartridges can fit some American Standard valves — but only when the “fits faucet brand” and model match are confirmed, not based on visual similarity alone.

Replace the fixture when identification is impossible. If the faucet is heavily corroded, the trim cannot be removed without damaging tile or the countertop, or the cartridge is discontinued with no verified substitute, a replacement faucet is often the smarter economic call. OEM American Standard cartridges at retail run roughly $42 to $75 based on current Home Depot listings — add labor and one wrong-part order and a new faucet can cost less in total.

When to call a plumber: Call if the shutoff valves under the sink won’t fully close (don’t attempt handle removal with live water pressure), if the trim plate is seized and risks cracking tile, or if the fixture is a shower valve where a failed identification attempt could leave the shower unusable until the correct cartridge arrives. A short diagnostic service call is often cheaper than ordering two or three wrong cartridges.

What’s Next After Cartridge Identification

Once you have the correct American Standard cartridge kit confirmed:

• For general cartridge replacement procedure, see the Pillar 1 faucet repair hub for the full cluster of how-to guides.
• If you’re starting from “I don’t know what brand this is,” work through how to identify your faucet brand and model first — it covers the visual brand-mark cues that narrow you to American Standard vs. Delta vs. Moen vs. Kohler.
• If the faucet is still leaking after you’ve replaced the cartridge, the problem is often a worn seat, spring, or O-ring — why is my faucet leaking walks through each cause.
