Momcozy Flange Compatible with Momcozy M6

The Momcozy Flange Compatible with Momcozy M6, stocked by Fed is Best, is designed for parents using the M6 mobile-style wearable pump who want to improve comfort and support better milk flow. Because breast and nipple shapes vary widely, having access to multiple flange sizes gives you the chance to customise your set-up. Refreshed, correctly sized flanges can help you maintain a good seal, protect sensitive skin and support more efficient expressing.

Available sizes and variations

At Fed is Best the Momcozy M6 flange range includes several size options, such as:

• 15 mm – for smaller nipple diameters needing a closer fit.
• 17 mm – a compact option with slightly more room.
• 19 mm – a popular medium size for many users.
• 21 mm – a roomier fit for those who need additional width.

You can use the same size on both sides or choose different sizes for each breast if that feels better. Some parents also move between sizes at different stages of feeding, so having options available is helpful.

Key features and benefits

• Designed for compatibility with the Momcozy M6 wearable breast pump.
• Multiple sizes to support a more personalised, comfortable fit.
• Helps maintain a reliable seal for consistent suction.
• Allows you to refresh worn parts and avoid replacing the whole pump.
• Useful as spare flanges for work, home or travel kits.

Why correct flange size matters

When flange size is well matched, your nipple can move freely within the tunnel without rubbing or blanching, and the surrounding tissue is not pulled in excessively. This supports comfort and may help with more complete breast drainage. A poor fit, by contrast, can lead to discomfort, swelling or lower output. The Momcozy Flange Compatible with M6, available through Fed is Best, allows you to experiment within a range of sizes to find what supports your body best.

How to choose your size

To choose a starting size, measure your nipple diameter after a feed or pumping session and add a small allowance. Compare that measurement with the flange sizes of 15 mm, 17 mm, 19 mm and 21 mm. Try one size for a few sessions and then reassess. Comfortable pumping should not involve significant pain or visible damage to the skin. If you are unsure, a lactation consultant can help you interpret what you are seeing and feeling and can offer tailored suggestions.

Care, cleaning and replacement

M6 flanges should be washed after each use in warm, soapy water, rinsed thoroughly and dried completely. Follow Momcozy’s guidelines on sterilising and how often to replace parts. Over time, frequent washing and sterilising can affect flexibility and clarity. When you see cloudiness, stiffening or fine cracks, it is time to replace the flanges. With replacements available from Fed is Best, you can keep your kit up to date and ready for daily use.
