We recommend choosing a flange size that is 1-4mm larger than your nipple size. Not sure what your nipple size is? Check out our Flange Sizing Guide!

Check out our PetalSoft Pump Compatibility Infographic to find out! While some breast pumps are compatible with interchangeable flanges as-is, others may require a specific connector to allow for interchangeable flanges.

The PetalSoft flange features a clear Polypropylene outer structure with a flexible, floral Thermoplastic Elastomer (TPE) overmold. 

The PetalSoft Flange will be available for preorder via our IndieGoGo crowdfunding campaign. We anticipate launching our full shop site in June. 

- Momease strives to source safe materials that give you extra peace of mind when using your flanges every day. Polypropylene is one of the most common plastic materials used for breast pump flanges, and we have taken extra care to choose a specific grade of polypropylene that is suitable for food contact applications. Moreover, the flexible TPE material was chosen because its recommended uses include medical/nursing supplies, and it also boasts high purity and food-grade ingredients. Both materials are formulated without BPA, PVC, latex, and DEHP to ensure safety. Finally, all dyes are formulated for use in contact with food. 


See 'How should I care for my PetalSoft Flanges?' for recommended care instructions.

Sterilization/Cleaning:

Per CDC recommendations, breast flanges should be sterilized prior to first use and once daily, so this is the guideline Momease provides for PetalSoft Flanges. However, sanitization is most important if your baby is less than 2 months old, was born prematurely, or has a weakened immune system due to illness or medical treatment (such as chemotherapy for cancer). Daily sanitizing of pump parts may not be necessary for older, healthy babies, if the parts are cleaned carefully after each use. When we refer to ‘sterilization’, this means boiling parts in water for ~5 minutes or steam sterilizing (we do not recommend using UV sterilizers for PetalSoft Flanges). We recommend steam sterilization to increase the longevity of your flanges, as boiling can be hard on pump parts. If boiling, be sure to fill the pot with enough water to completely submerge the parts without them touching the hot bottom of the pot. ‘Cleaning’, on the other hand, refers to soap-and-water washing. While pump parts should be sterilized prior to first use and cleaned after each use, ongoing sterilization frequency is ultimately up to each mother and their comfort level based on their baby’s needs. Just note that daily sterilization can be harder on pump parts - especially flexible pump parts - so more frequent replacement may be necessary.

Replacement:

We suggest replacing PetalSoft flanges every 6 months, at the very least - however, frequency of use and sterilization frequency/method will impact part longevity, so you may need to replace your flanges more frequently for optimal performance. Be sure to replace your flanges as soon as they wear out and become cracked, warped, or damaged. Don’t wait for the calendar to tell you to replace your flanges - if your flanges feel different than they used to, or you begin to notice visible surface wear, replace them!

Storage/Handling:

We recommend storing and handling PetalSoft Flanges with care - they are, after all, delicate flowers designed for flexibility! Avoid tossing them into your pump bag underneath heavy parts that may deform or crush them.
