Designed for Life Factory bottles and most narrow-neck bottles, this adapter gives a secure connection to the portable warmer. Before ordering, compare your bottle neck style to the photos to confirm fit.

A compact ring with a low profile, made to sit neatly between bottle and warmer. Its smooth surfaces wipe clean easily, so it stays hygienic between uses.

Attach the adapter, flip and twist the warmer onto the bottle, then warm as usual. Ideal for keeping your feeding routine consistent at home or on the go.
Picking the right adapter is mostly about matching neck style and your usual feeding routine.
- Confirm neck type: Look at your bottle's neck, not its overall shape. This adapter is for narrow-neck bottles.
- Compare to photos: Use the product images to compare the adapter profile with your bottle's threads and rim.
- Think about routine: If you use a portable warmer often, choose an adapter that stays simple to attach on the go.
- Cleaning needs: Wipe or hand wash the adapter after feeds, and dry fully before storage to keep it sanitary.
- Plan for returns: If it does not fit, our 30-day return policy makes exchanging or returning straightforward.
Does this include a bottle or warmer?
No, the adapter is sold separately. It is an accessory only, the warmer and bottles are not included.
Which bottles will it fit?
It is made for Life Factory bottles and most narrow-neck bottles. If you are unsure, compare your bottle neck to the product photos or contact support for help.
How do I clean the adapter?
Hand wash with warm, soapy water and rinse thoroughly. Dry completely before storing or reattaching to maintain hygiene.
What if the adapter does not fit my bottle?
If it does not fit, contact our human customer support for troubleshooting and exchange options, or use our 30-day return policy.
