Updated 21mm Flange and Duckbill Valve Compatible with Spectra Breast Pumps

This 6-piece set includes: 2 flange pieces (21mm) and 4 duckbill valves, compatible with Spectra S2, Spectra S1, Spectra 9 Plus, and SG breast pump accessories. These are replacement parts, not original Spectra flanges or duckbill valves.

The updated version of these parts features a soft rim design. Ordinary flanges are made of hard material, which can cause discomfort after prolonged use. However, the improved design of these flanges reduces such discomfort by incorporating a soft, flexible rim that is gentle on the mother's skin. Improperly fitted flanges can lead to discomfort and reduced pumping efficiency.

The updated flange design offers a 106-degree wide-angle opening in an oval shape. This shape creates a better fit during pumping sessions and helps ensure a tight seal against the mother's skin for efficient milk expression.

The diaphragm valves in this set feature an anti-backflow design, preventing milk from refluxing. This valve design, along with the anti-overflow features of the duckbill valves, ensures that milk only flows in the desired direction, keeping the system clean and free from contamination.

These replacement pump parts are made of food-grade silicone, which is BPA-free, safe, soft, and odorless, making them skin-friendly for both the mother and the baby. The individually-combined design allows for easy disassembly and cleaning. The parts should be cleaned with soapy water and rinsed with clean water. Avoid using hard brushes and do not place the parts in a dishwasher. The thin tips can be cleaned with fingers.

In summary, this 6-piece set of replacement flanges and duckbill valves offers several key benefits:

1. Soft, flexible rim design for increased comfort during prolonged use.
2. 106-degree wide-angle, oval-shaped flanges for a better fit and efficient milk expression.
3. Anti-backflow and anti-overflow valve design to prevent milk reflux and ensure a clean, contamination-free system.
4. Food-grade silicone construction, BPA-free, safe, and skin-friendly.
5. Easy disassembly and cleaning with soapy water, avoiding harsh brushes and dishwashers.

These replacement parts are compatible with Spectra S2, Spectra S1, Spectra 9 Plus, and SG breast pumps, providing a convenient and improved solution for mothers who require replacement accessories for their breast pumps.
