More About Timelines

Timelines are estimates, based on our averages and couriers’ commitments. We always aim to get your order to you quicker than this — but they’re not a guarantee. Wherever your order is in the journey, we’ll keep you updated every step of the way.

Returns Made Easy

Unfortunately, we can’t accept returns on this product once it’s been opened. This is usually because:

If there’s a defect or fault, though, it’s always covered as a warranty claim.

If the item is still unopened, you can return it within 30 days of receiving it. Just request a return from your account or through our chat, and we’ll handle the rest.

Returns are always free within 7 days. After that, if you’re returning it because you’ve changed your mind, you may need to cover the return cost. You can send it back yourself, or we can arrange a courier and give you an upfront quote — direct from the courier. If your return is for any other reason, it’s free.

Goes great with ...
  • Keeps Suction Consistent: Replacing worn diaphragms helps maintain reliable suction and steady pumping performance over time.
  • Model-Specific Fit: Compatible with both the Momcozy M5 and M5 Smart wearable breast pumps.
  • Handy Two-Pack: Comes as a set of two, so you have a spare ready when you need it.
  • Soft, Flexible Silicone: Made from soft, flexible silicone that flexes with every pumping cycle.
  • Easy to Replace: Simple to swap in during your routine pump care.
  • Routine Maintenance: Momcozy recommends replacing approximately every three months under regular-use conditions.

The Momcozy M5 Silicone Diaphragm (2 Pack) is a set of replacement silicone diaphragms designed to help maintain reliable suction and consistent pumping performance in compatible Momcozy wearable breast pumps. If your pump feels like it's lost some of its pull, or you're simply keeping on top of routine maintenance, these are the small soft parts that keep the suction mechanism working as it should.

The diaphragm is one of those unassuming components that does a lot of quiet work. It forms part of the pump's suction mechanism, helping to regulate airflow and support the vacuum pressure needed to express milk. Because wearable pump parts take regular strain through pumping, washing and sterilising, the silicone naturally softens and wears over time — so having a fresh pair on hand is part of keeping your pumping routine running smoothly.

Compatibility

These replacement diaphragms are compatible with both the Momcozy M5 and M5 Smart wearable breast pumps. Momcozy advises against mixing accessories between unrelated pump models, as each wearable system is engineered differently — so it's worth confirming your pump model before ordering to make sure these are the right fit.

How it Works

  • Regulates airflow: During pumping, the diaphragm helps manage airflow within the pump's suction mechanism.
  • Supports the vacuum: It helps maintain the vacuum pressure required for milk expression, which is what keeps suction feeling consistent session to session.
  • A wear component: Soft, flexible silicone flexes with every cycle, so replacing it routinely helps support efficient expression as the part ages.

Replacing your diaphragms

These are easy to swap in during routine pump care. Momcozy recommends replacing the silicone diaphragms approximately every three months under regular-use conditions, though how quickly they wear depends on how often you pump and clean them. Keeping a spare set means you're not caught out when suction starts to feel weaker.

Best For

The Momcozy M5 Silicone Diaphragm (2 Pack) is a great option for parents who:

  • Pump regularly with a Momcozy M5 or M5 Smart and want to keep suction performing consistently
  • Prefer to stay ahead of maintenance with fresh soft parts on hand
  • Need to replace a diaphragm that has softened, warped or lost its seal
