This product is great to have on hand because you don’t know when your pump is going to need any sort of replacements this works with the Phillips avent pump easy to remove and clean

I have a three year old Avent double electric comfort breast pump from when I had my first baby. Just had baby number 2 and unpacked the old pump and needed to replace these. I was pleased to see that they fit my old pump - I wasn't sure if they would since they have changed the design of the pump drastically since 2012. But they fit right into the flange and the pump works as if it were brand new. Suction is great. I'm very happy.

I ordered these to replace the ones I lost for my pump (Amazon product ID number of my pump is B004HFQOLS). They are the right ones and work well.

I needed to replace the duckbill pump valves for the manual Avent pump I had purchased when I had my first baby which was apparently discontinued (I still find it convenient to use with my second child 3 years later at times when pulling out my electric double pump wouldn't work) - this is a great option for the replacement valves, which are easy to tear or run through the garbage disposal (whoops). I was a little worried about buying a non-Philips Avent part but this worked perfectly!

I’m not too impressed. I have a manual Avent Phillips. I use them for it. It sits in the groove quite loosely and as a result I don’t feel much suction.

I have had my old Avent pump through all 3 of my boys and I have not lost any of these little guys until recently. I was panicking because my pump is the older model and I could not find the part on even the Phillips website. Of course, Amazon was there for me! These fit my pump perfectly and I even was able to replace the older ones that I still had. These were a life saver!

Bought these due to convenience of being on Amazon and not having to call Avent for shipment. Have had issues finding suitable replacements for the valves for my pump (double electric, purchased early 2011), these work just the same as the Avent produced kind. Haven't noticed any issues, only used them twice so far though. Will update if they seem to wear out faster or degrade in quality. So far, so good.

I needed replacement Parts for a Avent Electric Twin Breast Pump. I opted to receive the convenient "bundle" option which came with the Valves, Diaphragm, and Cushion for less then $30. I replaced and put all the items together to test it out and it seems like they are all doing their job.
