JIMOWANG Flange Inserts 15/17mm – 8pc, 24mm Shield Compatible (Momcozy/Medela/Spectra)

Customize your pumping fit with JIMOWANG flange inserts

The JIMOWANG 8 piece flange insert set offers flexible sizing for wearable breast pumps. It includes two inserts for each size across four sizes, enabling you to mix and match to fine tune the tunnel opening for your session. When paired with a 24 mm shield, this setup can help tailor comfort and flow. Note that it is not compatible with 27 mm shields.

What you get and how it helps

• Eight inserts in total, with two pieces per size, providing four distinct size options for convenience.
• Sizes include 15 mm and 17 mm inserts to reduce the tunnel opening from 24 mm to a better-fitting size.
• Designed to work with a broad range of 24 mm shield pumps from major brands, including Momcozy, Medela, Spectra, and more.
• Crafted from BPA-free food-grade silicone and easy to clean, supporting everyday use.

Compatibility and versatility

These inserts are crafted to fit many wearable and conventional cups, compatible with Momcozy S12 Pro and S9 series, as well as widely used 24 mm shields from Medela, Spectra, Elvie and other brands. They also suit pump cup ecosystems from TSRETE, Paruu, Luxlady and similar makers, offering flexible integration into your routine.

Material, care, and maintenance

• BPA-free silicone that is durable, flexible, and easy to clean with soap and water.
• Care tips: rinse after use, wash with mild soap, and let air dry to maintain material integrity.

Practical tips and replacement guidance

• Size selection matters for comfort and pumping efficiency; monitor how the nipple appears during pumping and adjust as needed.
• Replacement is suggested every 1 to 2 months to maintain fit and hygiene.

Real-world scenarios

Picture switching between inserts to suit different pumping sessions. A snug 15 mm can feel reassuring during brief sessions, while a 17 mm option may offer a slightly looser feel for longer pumping. The ability to tailor the fit supports a more controlled, calm experience without guaranteeing specific outcomes.

Sensory and design notes

The soft, flexible silicone offers a gentle touch against the skin, while staying secure with the shield. Lightweight and easy to maneuver, the inserts support a practical, low-friction pumping experience across compatible devices.

Important note

This insert set is not intended for 27 mm shields. For best results, ensure the shield size matches the insert size you select.
