Pump Parts Compatible with Spectra S1 S2 9 Plus - Replacement Kit

In this review of the Pump Parts Compatible with Spectra S1/S2/9 Plus kit, the bottom line is simple: this replacement set is for breastfeeding parents who need a full, ready-to-use spare parts kit that matches Spectra pump fit and suction without paying for OEM pricing. The kit contains multiple flanges, valves, backflow protectors, tubing and larger 180ml bottles, so it covers most everyday needs and travel situations. It is especially useful for those who pump frequently and want duplicate parts to speed assembly and cleaning.

Key Features

• Complete 4-set kit: Includes four flanges, four duckbill valves, four backflow protectors, four tubes and four 180ml bottles so you can double up parts for simultaneous cleaning and use.
• Compatibility: Designed to be interchangeable with Spectra S1, Spectra S2 and Spectra 9 Plus pumps so most Spectra owners will get reliable fit and suction performance.
• Upgraded flange design: The flanges use a soft rim with a thicker edge, smoother angle and longer tunnel to improve seal and milk collection efficiency during pumping.
• Food grade silicone: All silicone parts are made from 100% food grade material, are BPA free and can be sanitized with steam or boiling water for safe baby use.
• Large capacity bottles: The 180ml bottles give extra storage for milk or baby food, and include screw rings and a rewritable sealing disc for dated storage.

Who It's For

The kit suits breastfeeding parents who already own a Spectra S1, S2 or 9 Plus pump and need a cost-effective set of replacement or spare parts that provide full coverage: multiple flanges, valves, tubes and bottles in one box. It is also a good option for parents who travel or who prefer to have complete spare sets to avoid interruptions while parts are cleaned or sterilized.

Parents who require factory-original branded parts for warranty reasons or who need precisely the original manufacturer packaging should look elsewhere, since these are aftermarket replacements and explicitly not original Spectra accessories.
