So these did fit into my momcozy pumps HOWEVER they don’t create a perfect seal to the flange so Milk does get trapped underneath (if ur milk OCD like I am you can really carefully try to get the milk out when u take the parts apart to clean). U really have to press these hard into the flange upon insertion to create a good suction. I am however returning my momcozy so I’ll be retuning these as well
