Maymom 3rd Gen Thread Changer: Spectra S1/S2 Wide Mouth to Medela, Ameda Narrow & More

Expand Your Bottle Compatibility with the Maymom 3rd Gen Thread Changer

The Maymom 3rd Gen Thread Changer is a compact two-piece converter designed to broaden your pumping setup by letting Spectra S1/S2 wide-mouth flanges work with standard bottles. Each pack includes two genuine Maymom bottle size changers with an anti-leaking and anti-slip o-ring, created to help you connect quickly and securely during busy mornings or late-night pumping sessions. The result is a smoother, more versatile experience that keeps your kit flexible without requiring multiple separate parts.

Designed to fit real-life routines, this converter aims to reduce common issues that can derail a pumping session. With a soft, secure seal and careful threading, it works to minimize leaks when you bend over to reach the bottle, and it helps prevent the bottle from unscrewing unintentionally. The design also avoids interference with the duckbill valve, so you can focus on comfort and efficiency while you pump.

What You Can Expect

• 2x 3rd Generation genuine Maymom bottle size changers, each equipped with an anti-leaking and anti-slip o-ring
• Easy screw-on to both wide-mouth flanges and standard-sized bottles for broad compatibility
• Designed to work without interfering with the duckbill valve, reducing setup hassles
• May help keep connections secure during movement, with a lower risk of unscrewing

Compatibility, Safety & Care

Use the Thread Changer with Avent and Spectra S1/S2 flanges to pair with standard bottles such as Medela, Ameda (narrow mouth), Lifefactory, and the original Dr. Brown Narrow bottles. Note that it will not fit wide-mouth Dr. Brown bottles; it is intended to replace the wide-mouth Spectra setup where applicable. For stability, Maymom recommends using a bottle stand to help prevent tipping during pumping.

As a BPA-free and dishwasher-safe option, this product aligns with FDA food-contact guidelines. Maymom provides safety test reports online for reference. With Maymom, you benefit from a brand you can trust and USA-based customer service ready to assist with questions or setup advice.
