20mm Flange Pump Parts Compatible Spectra S1 S2 9 Breast Pumps Replacement,Full Set Replacements Include Flange Backflow Protector Membrane Duckbill Valve Tube,Not Original Accessories

Bought this set to replace my parts on my specta gold! Have bought it a couple times when I needed to down size my flanges! Was definitely worth the money compared to the brand name parts

These go perfectly with my spectrum pump and are a good alternative to the expensive spectrum parts

These are a great alternative to the Spectra pump parts for the S1 pump that my wife uses. We have not noticed any difference between these and OEM parts, which is a great thing!

This pump cups are good quality. The hoses are a little thin for the connection and wear overtime. Other than that it's a good replacement set.

These are seemingly compatible with my Spectra, however, the replacement flanges I ordered in 19 are not a 19 (or at least are not the same as my Spectra 19s). I didn't end up using the flanges because I got a clogged duct from them not fitting right. The soft silicone parts are great though (and frankly more important to swap out) so really good for switching those parts out.

The pump cords are incredibly short and the sizing is not correct. I have several sets of 18mm and this is much larger. It also comes all shoved into a very damaged unlabeled box. Do not order this, not at all worth the money.

Much more affordable than spectra flange replacements, and they work just as well for me personally. I recommend having multiple sets of flanges for times you don't want to wash in between uses or use the fridge hack.

These pump parts are really comparable to my pump's original parts. I like that it's compatable with a variety of pumps - both my travel and wall pump work with this set. Using new parts keeps my supply up and love how affordable this set is!

Great value. As good as the spectra ones.
