Some breast pump accessories do need replacing regularly to maintain performance. If you notice that your pump seems to have lost suction, the first thing you should do is take a look at your parts, particularly the valves, and inspect for wear, fraying, or stretching and replace if needed.

1. Diaphragm and duck valves need to be replaced every 3 months;

2. Backflow linker and flange shields need to be replaced every 6 months

Reviews Summary
Customers say these replacement parts fit their pumps perfectly and work just like the originals. Many reviews mention buying extras to avoid constant washing between uses. While some note receiving only one piece instead of a pair, most find the replacements sturdy and reliable. Common feedback includes appreciation for the easy availability of spare parts, though a few mention the price being on the higher side. Users report needing replacements every few months with regular use. The parts integrate smoothly with existing equipment, and several customers note subtle design improvements over original components. Some mention the convenience of having backups on hand for busy days. A few point out that certain components, like flanges, need to be purchased separately.

    I like how it feels thick and sturdy as opposed to the more flimsy ones I've gotten off amazon.

    Works great

    I was so relieved to find this replacement part for my breast pump! Its the piece that wore out the fastest on my pump, so I was really excited to see it available on their Amazon store. It fits perfectly and works just as well as the original. Plus, the price is super reasonable, which makes it even better. Definitely a great replacement option if youre in the same boat!

    Authentic replacement

    This is exactly what it is. A replacement valve for the momcozy M9 pump. Helpful to have on hand. Generally need to replace every three months or so.

    Makes pumping more comfortable

    This insert makes pumping more comfortable. I feel like it increased my supply slightly because I have elastic nipple, and this makes pumping more comfortable and more tolerable.
