24mm Replacement Pump Parts Compatible with Spectra S2 S1 9 Plus - 4

In this review of the 24mm replacement pump parts kit for Spectra S2, S1 and 9 Plus, the bottom line is simple: it is a convenient, cost-effective way to keep a Spectra pump running with spare flanges, valves, tubing and bottles. The kit includes four complete 24mm flanges plus duckbill valves, backflow protectors, tubing and four wide-mouth bottles with collars and sealing discs, making it useful for parents who need backup components or a full milk-collection set. This review focuses on fit, function and real-world usability compared to original Spectra parts.

Key Features

• Complete kit: The set contains four 24mm flanges, four duckbill valves, four backflow protectors, four tubes and four bottles with collars and sealing discs, providing multiple full replacement assemblies in one purchase.
• Compatible design: Parts are interchangeable with Spectra S2, S1 and 9 Plus pump components so users can swap them with original pieces without changing pump operation.
• Closed backflow protection: Backflow protectors are designed to form a secure seal with tubing and prevent milk from entering the pump, protecting the motor during pumping cycles.
• Bottle convenience: Bottles include leak-proof collars and sealing discs and work with common wide-mouth nipples, allowing milk to be stored, refrigerated and warmed safely.
• Durable materials: All parts are BPA free, comply with food-contact regulations, and can be cleaned by boiling, steam bags or dishwasher-safe cycles for routine hygiene.
• Extended tubing length: Tubing is longer than original tubing, which can improve comfort and reach during hands-free or multi-position pumping.

Who It's For

This kit is well suited for parents who already own a Spectra S2, S1 or 9 Plus pump and want a ready supply of replacement parts or an extra milk-collection set for travel, daycare or backup. It is especially useful for households that pump frequently and need spare valves and backflow protectors to maintain suction and hygiene.

Those who should look elsewhere include users who require original manufacturer-branded parts for warranty reasons or consumers who need nipple tops included, since nipples are not part of this kit. Also, if a different flange size is required, choose the appropriate size rather than this 24mm set.

Pros & Cons

Cons
