Sizing, bottle compatibility, and practical tips

Flange sizes span a broad range from 13mm to 30mm, allowing you to explore the best fit for your setup.

Real-world use often involves swapping worn components without changing other parts of the system. This replacement set offers a budget-friendly alternative that aims to preserve your pumping routine, particularly when originals aren’t readily available. As with any accessory, confirm compatibility with your exact pump model and bottle system before use.
