LOZAEVE 17mm Silicone Flange Inserts – 2pc for Spectra S1/S2, Medela 24mm Shields, Freemie 25mm Cups

LOZAEVE 17mm Silicone Flange Inserts — Key Details

Meet LOZAEVE 17mm silicone inserts, designed to work with popular shield systems while offering a tailored fit for smaller nipples. By reducing a standard 24mm tunnel to 17mm, these inserts can adapt to a variety of pumping setups, including Freemie 25mm cups. The result is a flexible option for caregivers who want to explore fit without changing their entire shield ecosystem.

Constructed from BPA-free silicone, the inserts blend a soft, flexible feel with durable construction. They stay inside the shield during pumping, helping to maintain a consistent opening and a seal that can feel more secure for some users. This makes them a practical choice for households that rotate between different pump brands or shield sizes.

Why this matters for your pumping routine

Comfort and fit are important factors in many pumping sessions. While outcomes vary, a snug, well-aligned tunnel can contribute to a steadier seal and a sense of reduced pinching during expression. The LOZAEVE inserts are marketed as a compatible, reusable component that can be paired with your existing shields without needing a full shield replacement.

Key compatibility includes a range of widely used shield sizes and cups, ensuring you don’t have to fully commit to a single system. The silicone design is easy to clean and sanitize between uses, supporting a simple, low-maintenance routine for busy days.

Who might benefit

• Moms with smaller nipples seeking a more secure, comfortable seal
• Users of Spectra S1/S2 24mm shields, Medela 24mm shields, or Freemie 25mm cups looking to reduce tunnel size to 17mm
• Caregivers evaluating fit across multiple brands while preserving shield compatibility

Practical notes for measuring and fit: if your nipple diameter post-pumping falls around 14–16mm, this insert may align with your shield’s opening. If you measure pre-pump circumference around 37.68–43.96mm, you can gauge whether a 17mm tunnel could be a good fit for your routine.

Care and usage tips

• Rinse after pumping and sanitize as needed between sessions
• Store the two pieces together for quick swapping between pumps
• Test fit with your existing shield system to avoid over-tightening or gaps

This product is sold as a two-pack and is intended to complement your current shield setup, not replace it. Use as needed to explore fit, comfort, and potential efficiency gains in your individual pumping routine.
