Nenesupply Spectra Pump Parts Kit — 21mm Flange, Valves, Bottles for S2/S1/9 Plus

Overview

Meet the Nenesupply Pump Parts Kit, a comprehensive set designed to work with Spectra S2, S1, and 9 Plus pumps. While these parts are not labeled as original Spectra accessories, they are crafted to fit and perform closely with Spectra systems, offering a practical alternative that supports your pumping routine with consistent materials and design.

What’s Inside

• Two 21mm flanges for a comfortable fit during sessions.
• Two duckbill valves designed to help maintain a steady flow.
• Two backflow protectors to protect the pump’s internal mechanism and keep the system closed.
• Two bottles with leakproof caps to store and transport milk safely.
• Two tubings that pair with the bottle collars and nipples for flexible setup.

This bundle is designed to be compatible and interchangeable with Spectra parts, including the bottles, and is built to support routine pumping with a complete, ready-to-use kit.

Compatibility & Performance

The kit mirrors the core suction and seal characteristics of the original components, helping to form an airtight connection across cycles. With a wide range of flange sizes available in the broader lineup (15mm–30mm), you can select the right fit to suit comfort and pumping style, while keeping the tubing and backflow system secure.

• Multiple flange sizes offer a customizable fit for different comfort needs.
• Interchangeable with Spectra parts to support a flexible pumping setup.

Safety, Cleaning & Care

• All parts are BPA-free and designed with food-contact safety in mind, backed by independent lab testing.
• FDA-compliant materials help you feel confident in everyday use.
• Dishwasher safe and compatible with steam cleaning, boiling water, or microwave-steam bags for easy sanitization.
• Leakproof bottles with sealing rings keep milk contained during storage and travel.

The bottles tolerate a wide temperature range (-20 to 100 C), enabling fridge storage and simple warming when needed, while maintaining bottle compatibility with Nenesupply, and often with Avent and Spectra collars and nipples.

Design, Comfort & Real-life Use

The flanges feature smooth, comfortable angles to reduce irritation during pumping. A flange tunnel of at least 32mm supports a variety of nipple shapes, including stretched options, making this kit suitable for different body types and pumping preferences. In everyday use, you can assemble the parts quickly, switch between sessions, and carry the bottles for storage or travel with less gear to manage.

Storage & Travel

Thanks to leakproof bottles and durable materials, you can store milk safely in the fridge and heat it with a bottle warmer when needed. The compact kit is easy to pack for outings or hospital visits, helping you maintain your pumping routine on the go.
