Increase your milk storage supply with the Spectra Premium Accessory Kit. The 24mm of 28mm breast flange kit replaces your original Spectra breast pump parts and helps maintain the proper suction and efficiency for the S1, S2, S3, SG and 9 Plus pump models.

If double pumping, we recommend getting two kits. All Spectra replacement parts are BPA/DEHP-free and are to be replaced every 3-4 months for optimal performance.
