Although many pumps have larger flange sizes, few offer flanges for moms with a nipple diameter smaller than 20mm. Our inserts are compatible with all ‘hard’ flange cups, including Spectra, Youha, Freemie, Imani and Medela. They can also be used with ‘bubbled’ flanges like Tommee Tippee and Philips Avent pumps, though the fit is not as great.  They fit best into a standard 24/25mm flange.  The soft silicone provides a snug fit into the flange, yet still ensures comfortable expressing.

Three insert sizes are available:

• 13mm (note: does not fit into 28mm flange)
• 15 mm (note: fit loosely into a 28mm flange)
• 17 mm
• 19mm
• 21mm
• 24mm (note: fits into 28-32mm flanges)
