NENESUPPLY Long Stem Backflow Protectors for Medela & Spectra S1/S2 Pumps — 2-Pack

Overview

Nenesupply offers a complete range of aftermarket pump parts designed to work with leading breast pumps from Medela and Spectra. The long stem backflow protector included here is compatible with Medela breast shields and Spectra S1/S2 pumps, helping you repurpose existing components without buying new original parts. Note: these are not original Spectra parts, and they are not compatible with Spectra flanges.

What’s in the package

• 2 long stem backflow protectors designed to fit tightly on compatible breast shields.
• Long end and short end variants (this product emphasizes the long stem version).

Key features and compatibility

• Closed system design to minimize contact between milk and tubing.
• Tight fit to help preserve suction power and prevent backflow protectors from slipping off.
• Made without BPA and safe for sanitizing by boiling or steam; complies with EU Regulation (EU) No 10/2011.
• Independent lab testing supports safety for materials contacting foods.
• Works with Medela breast shields and Spectra S1/S2 pumps as a cost-effective alternative to original parts.

Usage considerations

• Do not mix with Spectra flanges, as compatibility is limited to specific parts and configurations.
• Ensure proper photos comparison before purchasing to confirm compatibility with your model.

Practical benefits and user scenarios

For caregivers who already own Medela or Spectra components, these backflow protectors offer a way to maintain workflow, reduce part replacement costs, and keep pumping setups consistent across devices. While exact results vary, users may experience maintained suction and stable attachment during sessions.

Because materials are BPA-free and sanitizable, you can clean and reuse these parts as part of regular pump maintenance, potentially simplifying your routine while keeping safety considerations in mind.
