Flange di ricambio da 21 mm compatibili con 8782/8102/8122/8128/8116, accessori per tiralatte, senza BPA, 2 pezzi (flangia da 21 mm)

They are more of an oval then circle but if you are fine with that they work well.

Disappointed as this is not compatible with my pump but now I can't return it. Compatibility was unclear so I mistakenly thought this would be ok perfect and bought it.

Better than the original NCVI ones my pump came with. Slightly more oblong and the silicone is less wide so it’s more comfortable and less likely to have the silicone break from the plastic like my OG pair

Great quality, the box was intact and the pieces were actually nicer than the ones that came with the pump.

Unfortunately, I ordered these to replace the original pumps ones. The pink seal on both has broken which loses the suction and therefore it doesn’t work properly. I’m 7 weeks two sets have broken.
