15mm Soft Silicone Flange Insert
A successful and comfortable pumping experience hinges on obtaining the correct flange size. If you are using standard flanges (typically 24mm) and are struggling with pain, pinching, or disappointingly low milk volume, the culprit is often a flange that is too large. Introducing the Breast Pump Flange Insert (15mm)—the specialized flange size reducer engineered to perfectly size down your existing equipment, ensuring essential pumping comfort and superior milk output.
Precision Sizing for Efficient Milk Expression
Standard breast pump flanges are often far too large for many parents. Using oversized shields can lead to unnecessary areola irritation, friction, swelling, and nipple damage. If your nipple measures between 11mm and 13mm after a pumping session, the 15mm flange insert provides the precise narrow diameter needed for effective suction and milk flow. This ultra-precise flange size reducer ensures your nipple is centered and moves freely within the tunnel, which is crucial for efficient milk expression. Finding the correct flange size is not just about comfort; it is the definitive painful pumping solution that can lead to a significant boost in your overall supply.
Ultimate Comfort with Soft Silicone Material
This critical breast pump accessory is expertly crafted from flexible, medical-grade, BPA-Free Soft Silicone. Unlike the hard edges of standard plastic shields, the soft silicone insert creates a gentle, cushioned layer. This dramatically reduces friction and eliminates the trauma associated with ill-fitting equipment, translating directly to reduced soreness and greater pumping comfort during frequent or extended sessions.
Universal Compatibility for Your Electric Breast Pump
This 15mm silicone insert is designed to fit securely inside most standard 24mm breast pump flanges or shields, functioning as an indispensable flange size reducer. Its wide compatibility means it works as an essential electric breast pump part for major brands including Spectra, Medela, Willow, Ameda, Youha, and most wearable pump insert systems that rely on a 24mm shell. Avoid the expense of buying entire new flange sets; simply use this economical insert to convert your equipment to the correct flange size for drastically improved results.
