Medela Pump in Style Advanced parts include tubing, breast shields, membranes, connectors, and traditional kits. When choosing a replacement, look for a product listing that explicitly says it is compatible with the Pump in Style Advanced; the part categories alone do not confirm fit.
That distinction can save you from ordering something that looks right but is intended for a different pump. For example, a listing may name a breast shield or tubing without making clear which pump model it works with, so check the compatibility details before deciding.
This overview focuses on matching parts to the Pump in Style Advanced—not on setting up the pump or reviewing whether it is the right pump to buy. The sections that follow cover what the individual parts do, how to check a listing, which extras you might keep nearby, and what to verify before you order.
What does each pump part do?
Tubing, shields, membranes, and connectors each serve as a distinct part to identify when matching a replacement. [1] The product catalog groups these parts alongside traditional kits, so a kit may bundle multiple components rather than naming just one part. [1]
Identify the part you are replacing
Start with the component in front of you. If you are holding a flexible tube, look for tubing in the listing; if you are replacing the part that sits against your breast, look for a shield. [1] Membranes and connectors are separate categories, so do not treat either as another name for the tubing or shield. [1]
A quick way to avoid ordering the wrong type is to compare the replacement with the part currently in use. Note what it looks like and where it connects in your setup, then check that the listing describes the same component. If you are replacing a membrane, for example, choose a listing that identifies a membrane—not a kit whose contents you have not checked.
Read the listing before you order
Traditional kits are another category in the parts catalog, alongside tubing, shields, membranes, and connectors. [1] Because a kit can include several kinds of parts, read its contents rather than assuming it contains the one replacement you need.
Before ordering, check the part currently in use and compare it with the product listing. Look for the component name and any details that distinguish the item from a bundle; if the listing is vague, pause and confirm what is included with the seller. For example, if you need only a connector, make sure the listing actually identifies a connector instead of relying on a broad kit label.
This simple check helps you focus on the right component without guessing from a product photo alone. Match the name and description to the part you are replacing, then review the listing once more before checkout.
How can you check whether a replacement part fits?
A replacement fits only when the listing clearly matches the Pump in Style Advanced and the specific part you need. Before you order, look for the pump model name—not just “Medela”—and compare the listing’s component type and any model or kit details with your current part.

Read the compatibility wording
Start with the product title and description. Look for an explicit statement that the item is compatible with the Pump in Style Advanced; a broad label such as “Medela breast pump parts” does not confirm that it fits this pump. Medela’s parts catalog groups items into categories such as tubing, shields, membranes, connectors, and traditional kits, so check that the listing names the category you are looking for. [1]
A listing may mention more than one pump model, so read the full compatibility details instead of relying on a single model name in the title. For example, one listing describes 19 mm oval flanges as compatible with Medela parts and names Pump in Style, Symphony, Swing Maxi, Harmony, and PersonalFit Flex. That wording does not by itself confirm fit for the Pump in Style Advanced, so ask the seller if the listing does not name your exact model. [2]
Match the part and the kit details
Check that the listing describes the same kind of component you need, then compare any stated model, size, or kit details. If you are replacing a single piece, make sure the listing is for that piece rather than a bundle; if it is a kit, read which items are included before buying.
If the description is unclear, pause rather than guessing from the brand or appearance. Check Medela’s parts catalog or ask the seller to confirm that the exact replacement fits the Pump in Style Advanced. Keep the answer or product details handy while you compare listings, so you can verify that the compatibility wording applies to the item you plan to buy.
Which accessories might be useful to keep on hand?
Extra personal parts can be useful if you want a separate set for work or travel, so you do not have to wash parts between sessions. [3] For example, you could keep one set with your work bag and another at home, then choose the set that fits where you are pumping that day.
Medela lists accessory categories that include tubing, shields, membranes, connectors, and traditional kits. [1] If you are planning ahead, you might compare which categories are offered individually with the contents of a kit, then decide what would be convenient to have ready as a backup.
Check what comes in the kit
Do not assume every kit contains the same pieces: check the exact contents in the listing before you order. [1] For instance, if you are looking for a spare set to keep at work, make sure the listing names the components you actually want rather than relying on the word “kit.”
A simple way to plan is to write down what you would like to have available at home and away, then compare that list with each product’s stated contents. If you only need a second set for one location, a kit may offer more than you need; if you want several replacement items together, its contents may suit your plan. Check the current listing details before choosing, especially when comparing a complete kit with individual accessories.
What should you verify before you order?
Before you order, confirm the listing identifies the part for the Pump in Style Advanced and gives enough detail to check the fit. A familiar brand name or a broad label such as “Medela parts” may not tell you whether that specific item is right for your pump.
Check the product description
Read the full title and description, not just the search result. Look for “Pump in Style Advanced” as an explicit compatibility detail, then compare the description with the part you intend to replace. If the listing only says “Medela breast pump parts,” pause and look for more specific fit information before adding it to your cart.
Pay attention to model names in multi-model descriptions. One listing for oval flanges describes them as 19 mm and says they work with Pump in Style parts as well as several other Medela pump types [2]. That wording is more useful than a generic brand label, but you should still check the exact product details for the item you are buying.
Verify size and seller details
For a shield or flange, review any stated dimensions or size before checkout. For example, a 19 mm listing gives you a size to compare with the part you need; do not assume that the size or shape is right for you just because the listing names a compatible pump [2].
Also check what the seller says about compatibility and what is included in the package. Medela groups extra-parts listings into categories such as tubing, shields, membranes, connectors, and traditional kits [1], so confirm that the product page matches the specific item you meant to order. If the title, fit details, and package description do not agree, wait to buy until the seller clarifies them.
Before you check out, reread the current listing rather than relying on an old search snippet. Product details can differ between listings, so verify the model, size if stated, and package contents on the page for the exact item in your cart.
Common questions about Pump in Style Advanced parts
A replacement part may fit only when its listing confirms compatibility with the Pump in Style Advanced, so don’t assume parts swap between Medela pump models. [1] Check the product details for the exact model match before choosing an item.
Can parts from another Medela pump fit?
They might, but the Medela name alone is not enough to confirm fit. Compare the listing’s stated compatibility with your Pump in Style Advanced, and ask the seller to confirm if it is unclear. [1]
For example, if a replacement is labeled for a different Medela pump, don’t order it based only on the brand name. Look for an explicit fit statement for your model.
Can you buy individual parts or a kit?
Medela’s extra-parts catalog includes individual part categories as well as traditional kits. [1] Read the listing to see whether it is for one item or a bundle, then check exactly what the kit includes before you buy.
For instance, a listing for tubing is different from a kit listing; don’t assume a kit includes every part you need. Use the item description to confirm its contents.
Where can you look for replacement options?
Start with Medela’s extra-parts catalog or check a retailer’s listing for Pump in Style accessories. [1] A retailer describes additional personal parts as useful when you want a separate set for work or travel rather than cleaning parts between sessions. [3]
Whichever option you use, review the current listing and its fit details. If the page does not clearly identify compatibility, contact the seller before ordering.
Make your next replacement match the pump
The safest next step is to identify the replacement you need, then confirm the listing names Pump in Style Advanced compatibility before you order. This keeps your search focused on the right item instead of relying on a broad label such as “Medela parts.”
Start with the component you are replacing. For example, if you need a new membrane, search for that part by name and check that the product details specifically identify the Pump in Style Advanced. If you need a different component, use its name instead; Medela’s parts range includes tubing, shields, membranes, connectors, and traditional kits. [1] For more detail, see How to Use Medela Pump in Style Advanced: A Step-by-Step Guide.
Before placing the order, read the full listing rather than relying on the product title or a thumbnail. Confirm that the stated compatibility matches your pump, and check what the package includes. A kit may contain several items, while a listing for an individual part may cover only one component, so make sure the contents match what you intend to replace.
If the listing is brief, look for a product-details section or ask the seller to clarify the model compatibility and included parts. You can also compare the listing with the component you have in hand. For example, if you are replacing a single item, do not assume that a bundle is the right choice unless its contents include that item.
Product pages can change, so check the current details and kit contents at the time you order. In short, name the component you need and verify Pump in Style Advanced compatibility on the specific listing; then confirm the package includes the replacement you expect.
