The Momcozy Flange Insert is a soft silicone sizing insert that fits inside the flanges on your Momcozy M5, M6 and M9 breast pumps, letting you narrow the tunnel opening for a more personalised, comfortable fit. If the standard flange feels a little too big and pumping isn't quite as comfortable as you'd like, a smaller insert is a practical way to fine-tune the fit without swapping out your whole flange system.
Every breastfeeding journey is different, and a standard flange size won't suit every body. These inserts sit inside your existing flange and reduce the diameter of the tunnel where the nipple enters during pumping, so you can match the fit more closely to your own measurements. They're available in 15 mm, 17 mm, 19 mm and 21 mm, giving you room to dial in the size that feels right for you.
How it works
- Reduces the tunnel size: The insert slots inside your original Momcozy flange and narrows the opening where the nipple sits, helping you customise the fit more accurately to your nipple measurements.
- Soft silicone contact: Made from flexible, lightweight silicone designed for direct skin contact during pumping, so it can cushion the fit while you express.
- Keeps your setup intact: It works within your existing wearable pumping system rather than replacing the full flange, so you keep using the pump you already have.
Best For
The Momcozy Flange Insert is a great option if you:
- Own a Momcozy M5, M6 or M9 breast pump and find the standard flange feels too large
- Want to fine-tune your flange fit for a more comfortable pumping experience
- Pump regularly through the day and want a fit that suits your own measurements
It may not be what you need if your pump is a different model, since these inserts are designed specifically for the M5, M6 and M9.
Pandylane Pro Tip: Finding your size can take a little trial and error — nipple measurements guide the starting point, but comfort during pumping is the real test. If you're between sizes, it can help to have more than one insert on hand so you can compare which feels best over a full session.
