4packs 20mm Full Breast Replacement Pump Parts for Spectra S1 S2 9

In this review the IVARONAL 4packs 20mm full breast replacement pump parts are evaluated for parents who rely on electric pumps every day and need a ready supply of replacement components. The bottom line: this kit is for users of Spectra S1, S2, Spectra 9 Plus, Synergy Gold and several other compatible pumps who want a full, double-pump maintenance set that lets them pump directly into storage bottles. The most compelling reason to buy is that it supplies four full sets of flanges, valves, backflow protectors, tubing and 180ml bottles so you can replace worn parts quickly and avoid interruptions to breastfeeding.

Key Features

• Complete 4-pack: Includes four flanges, four duckbill valves, four backflow protectors, four tubes, four 180ml bottles and four one-piece caps so a user can equip or maintain two double pumping sessions with spares available.
• Wide compatibility: Works with Spectra S1, Spectra S2, Spectra 9 Plus, Synergy Gold and several other popular hospital-style pumps so it covers common household and travel needs.
• Food-grade silicone: All skin-contact components are made from BPA-free, food-grade silicone for safe contact with expressed milk and easy sterilization by boiling or steam.
• Improved suction design: The upgraded flange with a soft rim and longer tunnel aims to create a better seal and improve milk flow efficiency during pumping.
• Leak-resistant bottles: Each 180ml bottle includes a screw ring and sealing disc to pump directly into the bottle and reduce transfer waste, plus an extra one-piece cap for storage or travel.

Who It's For

This kit is best for regularly pumping parents who already own a compatible electric pump and want a convenient, full replacement set without sourcing individual parts. It suits those who pump both at home and on the go and need additional bottles that accept direct pumping and sealed storage.

It is not intended for users who require original, brand-specific manufacturer parts for warranty reasons or who need sizes other than the 20mm flange; those users should seek official replacement parts or alternative flange sizes tailored to fit.
