The Mompmuir Flange Inserts are designed to help you customize shield size without changing your pump. This 10-piece set offers 15, 16, 17, 18, and 19 mm options, making them broadly compatible with many popular 24–25 mm pumps from Medela, Spectra, Elvie, Lansinoh, and more. The result is a more personal fit that can feel gentler on the skin during express sessions.
Soft, transparent silicone delivers a comfortable touch while maintaining a reliable seal. While individual results vary, selecting a well-matched size may contribute to a smoother pumping rhythm and a more familiar pumping experience over time.
Crafted from transparent food-grade silicone and BPA-free. You can sanitize with water steam, boiling water, or microwave steam bags. Replacement every 1–2 months is recommended to maintain optimal performance.
