27mm Full Breast Replacement Pump Parts 4-Pack - Complete Kit

In this review the reviewer looks at the IVARONAL 4-pack 27mm full breast pump replacement parts kit and concludes it is a practical, budget-friendly option for parents who need a complete spare set. The kit is aimed at owners of Spectra S1, S2, 9 Plus, Synergy Gold and several other compatible pumps who want a full set of replacement components that can be used immediately for double pumping. The single biggest reason to buy is the convenience of getting four complete sets of flanges, valves, backflow protectors, tubing and 180ml bottles so you can replace worn parts or pack extras for travel.

Key Features

• Complete 4-pack: Includes four flanges, duckbill valves, backflow protectors with membranes, tubes, 180ml bottles, screw rings, sealing discs and one-piece caps so users receive enough parts for long term use or shared rotation between pumps.
• Wide compatibility: Designed to fit Spectra S1, Spectra S2, Spectra 9 Plus, Synergy Gold and other pumps such as Motif Luna and Cimilre, which reduces the need to search for model-specific parts.
• Food-grade silicone: All parts that contact milk are made from BPA-free, food-grade silicone, allowing safe contact with milk and simple sanitization by steam or boiling water.
• Improved flange design: The upgraded flange has a soft rim, thickened lip and a longer tunnel to help create a better seal and improve suction efficiency during pumping sessions.
• Leak-preventing bottle system: The 180ml bottles come with screw rings and sealing discs and include one-piece caps for storage and travel, enabling direct pumping into bottles with reduced transfer and waste.

Who It's For

This kit is ideal for parents using compatible double electric pumps who want a cost-effective way to replace worn or lost parts without buying single items. It is especially useful for busy households that need spares for daycare, travel or rotating parts between sterilization cycles.

Shoppers who require manufacturer-original parts for warranty or precise OEM tolerances should look elsewhere, and those who need flanges in sizes other than 27mm should verify fit before buying since this kit centers on a single flange size.

Pros & Cons

Pros

• Complete replacement set supplied in quantities for long-term use or simultaneous double pumping.
• Made from BPA-free, food-grade silicone and designed to withstand boiling or steam sanitizing.
• Updated flange shape and longer tubing aim to improve suction efficiency and reduce milk entry into tubing.
• Bottles with sealing discs and caps let you pump directly and store without transfer waste.

Cons

• These are third-party replacement parts, not original manufacturer components, which may concern buyers who prefer OEM items.
• The kit centers on a 27mm flange size only; users needing other flange sizes must source those separately.

Specifications

Our Verdict

For parents who need a ready-to-use, full set of replacement pump parts without sourcing each piece individually, this 4-pack offers strong value. The kit is a practical pick for double-pump users and travelers who benefit from spare flanges, valves and bottles; just bear in mind these are third-party parts and the flange size is fixed at 27mm.
