PUMPMOM-USBackflow Protector for Spectra, Replacement Breast Pump Backflow Protector for Spectra S1 S2 9 Plus SG Breastpumps Pump Parts, BPA Free

Great replacement parts for spectra!

Perfect fit for my Spectra S1!!

We recently stopped breast feeding and also the associated pumping.Keeping the supplies (tubes, duckbills, backflow preventers, etc.) clean and available started to become a challenge. We shelled out for a 2nd set of OEM parts, but even then allowing them to air dry (as was recommended to us by various sources) made it clear that additional sets would be needed.The cost of OEM parts was prohibitive so we've tried several different non-OEM parts.These seem identical to the OEM and didn't interfere with, or reduce the suction power of the pump. While the great design of the Spectra system means that you probably don't need to change/clean the backflow preventers each use, with these spares, we could have entire sets of Flange, Duckbill, Backflow Preventer and Bottle (x2) for each session, plus a spare for traveling or when it was too tiring to clean-up after a pumping session.

I used both a Spectra Gold and a Motif Luna on my 10-month pumping journey. These backflow protectors are designed to work with both Spectra and Motif pumps. The box comes sealed with a sticker, and each pair of backflow protectors is bagged together. You get a total of 4 individual backflow protectors in this box.Like all pump parts, these should be washed and sterilized before use.These heavily resemble both the style of backflow protector that came with my Spectra Gold, as well as the older style of Motif Luna backflow protectors. (See photos - these are all made of shiny clear plastic. Motif has now switched to a matte translucent plastic, but it functions identically.) See photos for a side-by-side comparison.Other than the brand name ("PumpMom" vs "Spectra"), I do not see any difference between these plastic parts and the OEM ones.The white silicone membrane is a little shiny, and feels resistant but malleable. It fits snugly with the plastic casing.This is a great option especially for the early days when you need to pump every 2-3 hours. Having multiple sets of parts can allow you to only wash a couple times a day - which can really make or break your sanity as a new parent!

These are so nice to have on hand because you need to replace the pump parts every 90 days but sooner if you are pumping more often. These look and feel exactly like the ones that came with my pump originally and fit just fine. They're the same size, same kind of plastic, and the tubing fits just fine as well.

These backflow protectors come in handy because I've had my original ones break if they fall off the counter, etc. And it's always good to have a backup set because the parts get worn out eventually anyway. They seem to be just as good quality as my original parts! I'd definitely recommend these.

Worst suction out of all the back flows I’ve ordered. I have 2 motif Luna’s for 2 different locations in my house and they tend to get broken so I’ve bought several sets. Bought this brand for first time and I don’t get as much milk AND it takes a lot of massaging and longer time to empty than other brands. I compare to my one in the living room and it’s definitely these that are the issue.Edit: seller reached out to me to help fix the problem! Could’ve just been a defective batch. Very nice and worked with me!

It does the job it's supposed to do, but what I really appreciate is that the larger outer case (that connects to the tubes) is actually snug and secure against the silicone diaphragm and smaller inner case. I've tried other brands where the larger case piece will pop off the silicone if you just bump the tubing. The plastic itself that the case is made of is also nice. It's got the tiniest bit of give to it so it won't crack when you attach it to the flange, which I've also had happen on another brand. Overall, I definitely recommend trying them. I'd use them again in the future for replacement pieces.
