Breast Pump Accessories Compatible with Spectra Replacement Pump Parts 19mm Flange, Spectra Pump Parts S1 S2 Replacements Full Set 2 Set (Full SET-19MM)

This is from the first use, I got more milk than I did with my factory spectra parts. They're very comfortable with the silicon flange pieces (I do still have small flange inserts in there for my size that look a little offset but they're still very effective) and have just as good suction as the factory parts, if not better. My favorite part is the size of the bottles, I don't have to transfer in the middle of a pump session and all the parts feel like a thicker stronger plastic. Highly recommend, great for the price. Will update if I have any issues down the rode.

Works great with the spectra S2!

Love having an extra set of pump parts (extremely time saving). It works great on my spectra pump and the bottles hold more milk than the Spectra bottles do which has been very convenient!

I was so happy to order my flange size instead of using flange inserts and having less to wash when I washed my parts, sadly I was sent the wrong size so I'm still stuck with using inserts. Ordered 19mm received 24mm. One of the valves has a piece cut out of it so I still have to use one of my old valves. The only good thing about this product is the bottles, the bottles are great but not worth getting sent the wrong parts and a faulty valve which is one of the most important parts. I would return but I desperately needed the new tubing and backflow pieces. Luckily I've got more valves coming in the mail I'll worry about the flanges another day and with a different seller.

Replacement parts that fit together well & worked perfectly with the blue spectra. Was glad to have extra parts to help extend time between washing cycles & extend life of parts

Flanges work well but the tubing is thinner/cheaper feeling than what came with the spectra pump

These worked great as replacement parts for my spectra pump. Could definitely tell an increase in suction once I put them on

Hard to see the size on the flanges if you have different flange sizes and don’t want to mix them up. The containers are wide so some milk gets stuck in the bottle when you try to pour it.
