Connects Freemie closed-system cups to Ardo Calypso, Ameda Purely Yours, Spectra S1 and Spectra S2 pumps. The set supports both single and double pumping with Freemie cups.
Although the tubing looks different from the original Freemie connection kit, it functions the same way. It is not made for the Freemie open system or Freemie Classic.
