TB Tbuymax 8pc Duckbill Valves 4pc Pump Seals Diaphragm Compatible with Wearable Elvie Breast Pump and Pump Parts Replacement Membrane Parts

Absolutely loved these to use as extras with my Elvie! I had previously ordered a different brand which were pink and they did not work at all. I believe they were too thin or loose so the pumps would not suction. These exceeded my expectations and didn’t give me any trouble! They shipped and were delivered very fast and are a good quality - thick yet pliable and worked perfectly.

These work great for the Elvie breast pump. They are much cheaper than the name brand replacement parts and work just as well as the originals.

These work perfect with the Elvie wearable pump. It is recommended to replace these parts every few months when regularly using your pumps so this is great to have on hand.

There's a good number of pieces here for the price and honestly when it comes to pump parts you can't have enough, in my opinion. The material is a little thinner that Elvie's so you need to be a little gentler but otherwise this is a pretty good dupe, stock up!

Purchased to replace every 3 months to keep my supply up. They work well! I’ve had no issues. Cheaper than buying from Elvie!

These duck bills and valves are a great cheaper option for replacement pieces for the Elvie portable pump. I sometimes think they work even better than the original ones that come with the pumps. Like they fit a bit more snug to the pump. Great product!

Wonderful dip for Elvie pump.

If you don’t want your supply to suffer, don’t get these. I thought my milk supply was dropping! I tried these for 2 days and was getting such low output. I went back to my original Elvie parts (which I had thought were wearing out and needed replacing) and started getting double production. These seals don’t even have the same shape as Elvie’s exactly. I’ll spend the extra money for the Elvie originals…
