Momcozy M5 Double Sealed Flange 27mm

The Momcozy M5 Double Sealed Flange (27 mm) is a replacement flange made specifically for the Momcozy M5 wearable breast pump. It's the part that sits against your breast inside the collection cup, so it plays a big role in how your sessions feel — helping to support a secure position, consistent suction, and comfortable hands-free pumping.

Flanges and other soft, milk-contact parts naturally wear over time with regular use and cleaning. Keeping a fresh one on hand means you can swap out a worn flange before it starts affecting your fit or the seal, so your pumping routine stays as steady and comfortable as it was on day one.

A double-sealed design built for wearable pumping

The double-sealed flange is designed to hold its position within the M5 cup and support the vacuum the pump creates. A good seal is what keeps a wearable pump working the way it should — when the flange is intact and correctly fitted, it helps maintain more consistent suction and supports efficient milk expression while you move about hands-free.

Fit and sizing

This flange is a 27 mm size. Flange fit is personal and isn't reliably guessed from bra size, so it's worth checking that 27 mm matches the size you currently use before ordering. Using the right size for your body is part of keeping expressing comfortable.

Compatibility

This is a replacement flange designed specifically for the Momcozy M5 wearable breast pump system. It's easy to assemble and replace, so fitting a fresh flange takes moments.

How it Works

• Double seal: The flange is designed to seal securely within the M5 cup, which helps the pump hold its vacuum during a session.
• Positioning: It supports a secure fit against the breast, keeping things stable while you pump hands-free.
• Wear part: As a soft, milk-contact component, it's meant to be replaced periodically so your fit and suction stay consistent.

Best For

The Momcozy M5 Double Sealed Flange (27 mm) is a great option for parents who:

• Use the Momcozy M5 wearable pump and currently pump with a 27 mm flange
• Want a spare on hand to swap in as parts wear
• Prefer to keep their existing pump running well rather than replacing more than they need to

It may not be the right fit if you:

• Use a different Momcozy model or another pump brand
• Aren't sure of your flange size — check your current size first, as 27 mm won't suit everyone

Pandylane Pro Tip

It's worth keeping an eye on your soft parts: if suction feels weaker or the fit seems off, a worn flange is often the culprit rather than the motor. Replacing the flange first is the simpler, more affordable place to start.
