Nenesupply Pump Parts Kit — Spectra Compatible (S2, S1, 9 Plus)

Designed to work with Spectra S2, S1, and 9 Plus pumps, the Nenesupply Pump Parts Kit provides a complete replacement set that mirrors many core functions of the original components. While these parts are not from the official Spectra brand, they are designed to be interchangeable with the parts that come with your breast pump, offering a practical option for keeping your pumping routine uninterrupted.

What’s included

• 4 x 21mm flanges
• 4 x duckbill valves
• 4 x backflow protectors
• 4 x tubes
• 4 x bottles with screw rings and sealing discs

Note: Nipples are not included in this kit.

Key benefits and practical use

• Air-tight seals that pair valves, backflow protectors, and flanges to help maintain consistent suction across pumping cycles.
• A closed system with a flexible backflow membrane to protect the pump while keeping milk flowing through a clean path.
• Longer tubing than some originals, which can reduce tugging and improve flexibility when positioning during pumping.

Leak-proof bottles and versatile storage

• Leak-proof collars and sealing discs provide a secure seal; bottles tolerate a wide temperature range from -20 to 100 °C and are fridge-safe.
• Collars are compatible with Nenesupply, Avent, and Spectra nipples, offering flexibility when building a pumping station.

Materials, cleaning, and safety

• All parts are BPA-free and FDA-compliant for food-contact materials. Cleaning options include dishwasher, steam, boiling water, or microwave-steam bags.

Comfort and fit

• Flanges feature smooth angles for comfortable pumping, with a 32mm tunnel to accommodate stretched nipples.

Real-life scenarios

Whether at home, at work, or on the go, this kit supports a flexible setup. Imagine swapping in the kit on a busy morning, maintaining steady suction while you handle other tasks, or adapting your station in a cramped space with a longer tube to ease positioning.

Quality and reliability

These components are designed for practical daily use, emphasizing safe materials, ease of cleaning, and compatible performance with common Spectra models. The kit aims to offer a practical, interchangeable option for families who want a consolidated set of parts in one affordable package.
