Need replacement parts for your Medela Pump In Style Advanced? This Maymom diaphragm cap faceplate is compatible with specific models of this popular breast pump. Important note - Medela has released several pump models that use different faceplates, so please check your existing part carefully before ordering. The key things to verify: your current faceplate should have 9 VDC or 12 VDC marked on the bottom right, include a Let Down Button hole, have horizontally arranged tubing ports, and NOT have a center power adjustment knob. If your faceplate matches these specifications, this replacement should work perfectly. The clear design is actually really helpful - you can easily see inside to check for any moisture or mold buildup, which is important for pump hygiene. This listing includes the faceplate (#6007132) and two tubing pieces to connect between the faceplate and breastshields. You'll need to reuse your old port plugs. As a mom-owned company, Maymom understands how important reliable pump parts are for breastfeeding journeys. Their products are designed to meet or exceed original equipment standards at a more affordable price. Having properly functioning pump parts makes expressing milk more efficient and comfortable. Whether you need replacements due to wear and tear, want a backup set, or are troubleshooting suction issues, having the right faceplate can make a big difference in your pumping experience. Always remember to consult your pump's manual and verify part numbers to ensure compatibility before purchasing any replacement components.
