Spectra - Duckbill Valve Replacement for Breast Milk Pump (Pack of 2) - Fits Small, Medium, Large, or X-Large Breast Shields and Flanges

I spent over 3 years pumping and these never let me down when I needed replacement parts. Reliable and always work very well. I will always buy name brand over the off brand ones that seem to not work as well. Thank you spectra

Perfect replacement

Worth spending the extra few dollars on getting the name brand spectra duct bills. See a notice in my supply within 2 uses.

Perfect replacement for the valves that got too loose. Fit perfectly.

Tried a few others but they are just not the same. These are authentic from spectra and fit my flanges like a glove. They are soft and function exactly as needed.

It fits perfecting on my spectra flanges and has great suction! Great replacement!

They work as intended. Didn’t realize how worn out the old ones were till I installed these.

Look, these work. They fit well, suction’s solid, and they’ll get the job done. But here’s the thing: so do a bunch of off-brand options that cost way less. And some of those actually last longer.I’ve used both the Spectra valves and third-party ones, and honestly? No huge difference—except in price. So unless you’re feeling super loyal to the brand or just want to toss something in your cart fast, you can absolutely stretch your dollar further elsewhere.These are totally fine. But if you're looking for value instead of just function, shop around!
