We get this question a lot. Are Pumpin' Pal flanges worth it? Moms tend to either love or hate their Pumpin' Pals. While there can be a variety of reasons, the most common reason is fit that can cause irritation. loss of suction and less milk output rather than a higher milk yield enjoyed by the moms who love them. If you want to try Pumpin' Pals you will need to pack a little patience and expect that there is a learning curve because unlike any others I have seen they are angled like the baby's mouth which when used correctly does often result in more comfort and higher breast milk yield.
Let's compare to Spectra which is a top choice with mothers today.
Difference in Sizing
| Spectra OEM Size | OEM Inner Diameter | Pumpin’ Pals Size | Angled Inner Diameter | Practical Fit/Feel |
|---|---|---|---|---|
| 16 mm | ~16 mm | 2XS | ~17–18 mm | Slightly looser than Spectra 16mm — good fit if 16mm OEM is snug |
| 20 mm | ~20 mm | XS | ~21–22 mm | Looser than Spectra 20mm — size may feel loose on many moms who use 20mm |
| 24 mm | ~24 mm | Small | ~25–26 mm | Noticeably looser than Spectra 24mm — may feel loose on moms who use 24mm |
| 28 mm | ~28 mm | Medium | ~29–30 mm | Slightly larger than Spectra 28mm — good if comfort over vacuum strength is the goal |
| 32 mm | ~32 mm | Large | ~33–34 mm | Larger than Spectra 32mm — extra comfort, less suction seal than OEM 32mm |
A standard OEM flange is around $14.99, while the Pumpin Pal bpa-free flange is around $19.99. Extra cost is for the silicone since it is more expensive to make which is $24.99 and the adapter to use with OEM valves and backflows is an extra $10 if you add it on to your purchase.
