Upgrade Your Pumping Comfort & Efficiency
Maymom offers a 21mm wide mouth flange designed to be compatible with Spectra S1, S2, and 9 Plus breast pumps, ensuring a comfortable and efficient pumping experience. This flange is ideal for mothers with nipple diameters measuring 18-20mm after a pumping session, providing a crucial fit for optimal milk extraction. Unlike generic one-size-fits-all solutions, Maymom provides a range of sizes to accommodate diverse needs, ensuring every mother finds her perfect fit. Imported from authorized US retailers and authorized brand partners, this part offers the quality and reliability expected by discerning mothers in India.
This Maymom flange features design improvements over original Spectra parts. It can be used with Spectra duckbills or Maymom’s own valve/membrane system, and may also fit other brands' duckbills. Additionally, it’s compatible with Spectra’s backflow protector, Maymom’s long/short stem backflow protectors, and Maymom’s tubing connector (sold separately) for broader pump compatibility. This flexibility allows for customization and replacement of worn parts, ensuring continuous and effective breast pumping.
The kit contains one 21mm wide mouth flange. For simultaneous double pumping, two units are recommended. This part is BPA-free and complies with US FDA regulations for food-contact plastics. It is dishwasher top-rack safe and steam sterilization safe. While not an original Spectra part, Maymom provides a high-quality, compatible alternative for your breast pumping needs. All customs duties and GST are included in the price, with delivery expected in 16-18 days.
Optimized Pumping Performance
Maymom flanges are engineered for comfort and efficiency, addressing the critical need for correct sizing in breast pumping. Unlike generic parts, Maymom offers a wide range of sizes, including this 21mm option, to ensure a proper fit for mothers with 18-20mm nipple diameters. This precision reduces nipple soreness and maximizes milk output. Sourced from authorized US retailers and brand partners, these parts are made from BPA-free, FDA-compliant plastic, ensuring safety for both mother and baby. The compatibility with Spectra, AVENT, and Maymom bottles adds convenience to your daily routine. All customs duties and GST are included, with delivery in 16-18 days.
Who It's For vs. Who Should Skip
This 21mm Maymom flange is ideal for mothers using Spectra S1, S2, or 9 Plus breast pumps who have nipple diameters between 18-20mm post-pumping. It's perfect for those seeking a comfortable, efficient, and safe replacement part. Mothers using other breast pump brands or bottle types not listed (Spectra, AVENT, Maymom wide mouth) should look for alternative Maymom flanges or adapters. Those needing a flange size outside the 18-20mm range should select a different Maymom size.
