Universal bottle/pump converter

Bottle Converter / Adapter

Pump Directly. Waste Nothing. Stress Less.

Designed for modern pumping routines, our Bottle Converter / Adapter lets you connect wide-mouth pump flanges to standard-neck bottles — so you can pump straight into the bottles you already trust.

No milk transfers. No leaks. No unnecessary fuss.

Made from BPA-free, food-grade materials, this adapter creates a secure, hygienic seal that helps protect every precious drop while simplifying your pumping routine.

What’s Included

• 2 × Bottle Converters / Adapters

Key Benefits

• Pump Directly Into Standard Bottles – Less handling, lower contamination risk

• Secure, Leak-Resistant Fit – Screws on tightly for peace of mind

Compatibility

Compatible Wide-Mouth Pump Flanges:

• Spectra

• Motif

• Cimilre

• Avent

• Maymom

Compatible Standard-Neck Bottles:

• Medela

• Dr. Brown’s (standard neck)

Important Compatibility Note

Some Spectra flanges are manufactured in two slightly different versions — one with a shallower connector and one with a deeper connector.

This adapter includes an anti-slip O-ring designed to work with both versions. With older Spectra flanges, you may notice a small visible gap once connected. This is normal and does not affect sealing or performance when properly aligned and tightened.

In short: it works — no overthinking required.

How to Use

1. Place the anti-slip O-ring onto the bottle converter

2. Attach the converter to a standard-neck bottle

3. Align with your wide-mouth flange

4. Screw in firmly until fully sealed

You’re ready to pump.
