My guess is that you wouldn’t need the converter for wide neck. The converter helps fit my small top Dr. Brown Bottles. I have put a plastic wide neck Dr. Brown right on the part. It fits a little lopsided but it stays in there. **Q: Is this compatible with tommy baby bottle?** A: No, it will not compatible with tommy baby bottle. **Q: Will this fit nuk bottles ? then pump with spectra or medea pump?** A: This adapter makes the wider mouth spectra pump part fit regular mouth bottles. The medela PISA already fits regular mouth bottles. ## Frequently Bought Together - PumpMom-us Pump Bottle Adapter, Baby Bottle Thread Changer Converter for Spectra S1 S2 Wide Mouth Flanges to Use Standard Sized Bottles.
