Momcozy FLANGE BREAST PUMP ACCESSORIES S9/S12 PRO 15MM

Optimize your pumping comfort and maximize your milk output. The Momcozy 15mm Flange Solutions are medical-grade, authentic breast pump accessories specifically designed to fit the award-winning S9 Pro and S12 Pro wearable breast pumps.

Whether configured as a standalone 15mm silicone shield or a precision-fit flange insert designed to slide into a standard 24mm or 27mm shield, this accessory is tailored for mothers with smaller nipple diameters. Using the correct size is critical to achieving a comfortable, tight vacuum seal, preventing painful areola pulling, and ensuring your pump delivers its full hospital-strength expression capability.

Key Features & Benefits

• S9 Pro & S12 Pro Precision Fit: Engineered as an authentic, factory-spec accessory. It integrates seamlessly into the collection cup tracking of your S9 Pro or S12 Pro wearable pump, preventing milk leaks and maintaining a steady suction rhythm.

• Tailored for Smaller Nipple Diameters: Ideal for mothers whose post-pumping nipple base measures between 11mm and 12mm. Sizing down ensures your nipple centers perfectly in the tunnel, eliminating rubbing, friction blisters, and blocked milk ducts caused by oversized flanges.

• Prevents Areola Pulling: When a flange is too large, excessive amounts of the sensitive areola tissue are drawn into the tunnel, which pinches the milk ducts and restricts flow. The 15mm tunnel isolates just the nipple, promoting a faster letdown and a higher milk yield.

• Premium 50A Soft Liquid Silicone: Crafted from premium 50A-grade liquid silicone that is ultra-flexible, velvety soft, and gentle against sensitive skin. It mimics an infant’s natural latch, distributing suction evenly to eliminate pinching.

• Double-Sealed Edge Armor: Features an advanced, form-fitting contour that securely hugs your breast. This layout prevents air gaps and loss of vacuum suction, allowing you to pump confidently while moving around or multitasking.

• 100% Safe & Toxin-Free Construction: Your baby’s milk purity is paramount. These components are completely free from BPA, BPS, PVC, phthalates, and latex, ensuring your liquid gold remains pure and contaminant-free.

Size Guide: Is the 15mm Size Right for You?

How to Measure: Use a nipple measuring ruler before a pumping session to measure the absolute diameter of your nipple base (excluding the surrounding areola).

• Choose a 15mm Size if: Your base nipple measurement is 11mm to 12mm.

• Signs your flange is too large: Your areola is pulled deep into the tunnel, your nipple bounces or stretches excessively inside the shield, or you experience low milk output despite high suction settings.

• Signs your flange is too small: Your nipple rubs tightly against the tunnel walls from the start, causing immediate friction pain, swelling, or restricted milk flow.

Care, Cleaning & Sanitization

Hygiene & Performance Protocol: Wash thoroughly with warm, soapy water after every single use. These silicone components are safe for quick steam or boiling water sterilization (up to 100°C / 212°F) for 3–5 minutes. To maintain optimal suction and protect the elastic properties of the silicone, avoid using stiff bottle brushes or abrasive scrubs inside the narrow 15mm nipple tunnel. Replacement Reminder: Lactation experts recommend replacing your silicone breast pump accessories every 2 to 3 months under heavy daily use, as worn-out silicone naturally stretches over time, leading to lower suction strength and decreased milk output.
