Review: Best replacement parts for my Spectra S2 - These replacement parts for my Spectra S2 were exactly what I needed! The set comes with clear instructions and images, which made swapping everything out super simple, even for someone like me who usually finds pump parts confusing. I especially appreciated the QR codes included; they linked directly to step-by-step instructions and even to individual replacement parts if I ever need to reorder just one piece. The parts themselves feel durable and well-made, and they fit my S2 perfectly without any issues. Everything works smoothly and has held up well after multiple uses and washes. It’s such a relief to have a compatible, high-quality option that makes pumping easier and less stressful. Highly recommend for any Spectra S2 user who wants reliable replacement parts without the guesswork!
Review: A must have! - This kit saved me! The duckbills work great with the manufacturer’s parts for my spectra pump. These pieces can be used interchangeably with the original pieces from my pump, there is no noticeable difference. I would recommend always having this set on hand, as it is easy for pump pieces to go missing. It is easy to clean and good quality, with stands the heat of steaming.

### ⭐⭐⭐⭐⭐ Highly recommend
*by A***O on January 24, 2026*

This flange and valve set was a total game changer during my breastfeeding journey. I loved having a wide range of different flange sizes to try—being able to find the right fit made such a huge difference in comfort and output. It really helped take the guesswork out of pumping. The standard flanges that come with most breast pumps simply don’t work for the average female, and this set finally addressed that gap. Better fit, less discomfort, and a much more positive experience overall. I truly wish I had found these sooner. Highly recommend to anyone pumping or breastfeeding!
