Nenesupply Pump Parts Compatible with Spectra S2 S1 9 Plus - Complete

Our review of the Nenesupply pump parts kit finds it best suited to parents who need a full set of replacement components for a Spectra S1, S2, or 9 Plus style pump. The biggest reason to buy is practicality: the kit contains a complete collection of interchangeable parts so you can replace flanges, valves, tubing, bottles and backflow protectors in one purchase. For anyone who values compatibility and a closed system that preserves suction, this kit offers a straightforward, cost effective option.

Key Features

• Complete kit: The set includes four 17mm flanges, four duckbill valves, four backflow protectors, four bottles and four tubing pieces so a parent can replace an entire pump kit at once.
• Compatibility: Parts are designed to be interchangeable with Spectra S1, S2 and 9 Plus components so users can mix with existing parts without special adapters.
• Closed system protection: Backflow protectors and valves form an air tight seal to keep milk away from the pump motor and maintain a hygienic pumping setup.
• Leak resistant bottles: Wide mouth bottles include caps and sealing rings that allow storage, refrigeration and warming within the stated temperature range.
• Durable membranes: The elastic, flexible membranes in the protectors are intended to maintain suction through repeated pumping cycles.
• Cleaning and safety: All parts are BPA free, comply with food contact testing, and can be cleaned by dishwasher, boiling water, steam or microwave steam bags.

Who It's For

This kit is ideal for parents who already own a Spectra S1, S2 or 9 Plus and want a full replacement set without hunting for individual pieces. It is also good for households that pump frequently and want spare parts on hand to rotate during cleaning or travel.

It may not be the best choice for someone who needs a different flange size than 17mm, or for a buyer who prioritizes long term durability above initial value; a few users reported flange breakage after repeated use and issues with suction on some units, so those who have experienced power or suction problems with their pumps should proceed cautiously.
