What it does
- Converts standard 28mm threaded PET bottles for use with sparkling water makers

- Reuse existing beverage bottles instead of buying proprietary cartridges
- 3D-printed on demand; test with your specific plastic before carbonating liquids
This adapter makes standard PET drink bottles compatible with your sparkling water machine. The 28mm thread design fits commonly available bottles you can purchase anywhere, while the precision-engineered top seats firmly into your machine's rubber sealing surface for a reliable, air-tight connection.
Perfect for reducing waste by repurposing existing bottles instead of purchasing single-use cartridges. The chamfered geometry ensures proper contact and leak-free carbonation.
Important: This is a 3D-printed concept model. Before using with any liquid or CO2, verify that the plastic material and print quality from your printer are suitable for food contact and pressure exposure. Always test carefully and follow your machine's safety guidelines.
