Medela Harmony Diaphragm, Puller and O-Ring Assembly #8007234

 (2 customer reviews)

After finding out the o-ring to my Harmony pump had been lost, I looked for a replacement. I feel this part is too pricey, which is why I only gave it four stars. However, it was what I needed, and there are few places to find it (Medela charges waaay to much for shipping). Delivery was quick, and the part arrived in a sealed, clear plastic bag within three days. I am happy with the purchase.

I needed to purchase a new diaphragm for my Harmony manual pump. I couldn't believe that it cost nearly half the price of the pump to purchase. It turns out this assembly is only $6 directly from medela. [edit: the price on amazon has dropped some since writing this review. Also, although medela only charges $6 for the part, medela does charge quite a bit for shipping (around $11). The item itself is fine, so I have modified my original star rating. The current price on amazon is competitive if you only plan to purchase this one part one at a time. I wish the pump part would last longer, but supposedly pump parts are expected to be replaced monthly. The original oring assembly on my harmony manual pump lasted almost three months (about ten to twelve uses total). I ordered multiple new oring assemblies directly from medela, since I expect to go through 2-3 more within the year.]
