Maymom, a specialized company, has developed this product to fit Spectra's S1/S2 pumps, as well as Spectra 9 and Spectra M pumps. It is widely recognized that using the correct size of flange (breastshield) during breast pumping is the most crucial factor in achieving comfort and efficiency. Acknowledging that every mother is unique, Maymom has designed more than 12 flange sizes, ranging from 13 mm to 36 mm, to accommodate the average mother and those with special needs.

Before selecting the appropriate size, it is recommended to measure your nipple diameter after a pumping session. The size selector in this listing will guide you to choose a flange that is 1-2 mm larger than your measured nipple diameter.

This Maymom flange offers several improvements over the original Spectra design. Firstly, in addition to Spectra's duckbills, you can use Maymom's valve/membrane system with this flange. You can also experiment with other brands of duckbills, valves, and membranes, as they are likely to fit. Secondly, this flange is compatible with Spectra's backflow protector, as well as Maymom's long stem and short stem backflow protectors. Additionally, you can use Maymom's tubing connector (sold separately) to connect this flange to various other popular breast pumps on the market.

The kit includes a flange with a wide-mouth bottle connection (purchase two units if you wish to pump both sides simultaneously). Maymom, an independent company, is not affiliated with Uzinmedicare, the manufacturer of Spectra pumps. The value Maymom offers is their dedication to caring for each individual mother.

The contents of the kit consist of two 13 mm shields and two wide-mouth connectors. The 13 mm shield is suitable for mothers with a nipple diameter of 11-12 mm after pumping. The shield and connector together form a breast pump flange, allowing for double pumping.

This flange features a separable two-piece design, unlike the one-piece Spectra flange. The two-piece construction facilitates easy assembly, disassembly, and cleaning. It also fits seamlessly with most hands-free pumping bras on the market and homemade bras.

The available shield sizes range from 10 mm to 36 mm, catering to a wide variety of nipple sizes. This set is compatible with Spectra Pump S1, Spectra S2, and Spectra 9 Plus, and it can only be used with wide-mouth (wide-neck) bottles, such as the Spectra wide-neck bottle, Avent bottle, or Maymom wide-mouth bottle. To make it compatible with Medela bottles, you can try the Maymom 3rd Gen Bottle Converter.

All the parts that come into contact with breast milk are BPA/DEHP-free, and the product is made by a US FDA-inspected company, Maymom. The kit is dishwasher-safe on the top rack and safe for steam sterilization. It is packaged in a retail poly-bag, sealed by the manufacturer, and is not an original Spectra flange, pump part, or accessory.
