Replacement Parts for Medela Harmony Manual Pump; 4 O-Rings, 2 Membranes by Maymom

Fit my medela hand pump perfect and really helped me get more life out of the pump.

I lost the little ring for my hand pump and this saved me from buying another one.

I used these to replace the duck valves on my Medela harmony after I noticed a decrease in suction and it fixed the problem for me. The replacement has held up great so far after roughly one month of daily use 1-2 times/day.

Everything was clean and exact to fit. Quality and durability was the same as the original ones. Easy to install and came with instructions. Opted for this over buying a whole new pump set.

Having spare parts on hand is necessary and the package is so small and great for storing in case I need a spare. It’s also necessary to change parts every so often so you get full efficiency of the product. You won’t be sorry having the extra parts on hand!!!

Needed extra replacement parts and these worked great! Glad I was able to get them so quick.

I personally think it’s silly that our hand pumps don’t come with all these extra parts and that we have to pay $7 to replace pieces that cost probably $.01. My opinion aside, these get the job done and fit perfectly.Pros: fit the Medela hand pump, easy to replace, stay on well, create a solid suctionCons: price for what you get, somewhat hard to clean because they’re so small

Works great, good value, durable, and exactly as pictured.
