Smarbore 2-Pack 19mm Flange Inserts for 24mm Shields – Compatible with Medela, Spectra, Willow, TSRETE, Momcozy S9/S12

Smarbore 2-Pack 19mm Flange Inserts for 24mm Shields

Designed to tailor your shield tunnel, these 19mm inserts slide into most 24mm flange systems to offer a more fitting pumping experience. They’re compatible with a broad range of popular pumps, including Medela, Spectra, Willow, TSRETE, and Momcozy S9/S12/S9Pro/S12Pro shields, giving you flexibility to reuse existing hardware. The inserts are made from soft, BPA-free silicone that feels gentle against the skin as you express milk. Note that these inserts are not intended for 27mm shields, so it’s worth double-checking your current shield size before use. The 2-pack provides a spare so you can rotate parts or adapt to a second pump in your routine without waiting for replacements.

What this size can mean for your routine

Real-life pumping often involves changes in comfort, nipple swelling, and daily surroundings. The 19mm interior aims to reduce excessive tunnel contact inside a 24mm shield, which some users find more comfortable during longer sessions or when adjusting to a new pumping routine. In practice, you might notice a calmer pumping rhythm, less pressure along the tunnel walls, and a clearer sense of fit as you try different configurations. Remember, your nipple should not rub or feel squished inside the tunnel; use the inserts as a test to discover the most natural feel during sessions. This option supports your ability to customize fit without making promises about outcomes.
