IVARONAL 10pc Duckbill Valves & 4pc Silicone Membrane Replacement Kit for Spectra S1/S2/9 Plus

Upgrade your Spectra pumping routine with the IVARONAL replacement parts kit. Designed to fit Spectra S1, S2, and 9 Plus models, this kit provides a practical option for ongoing maintenance. While not the original Spectra parts, the set focuses on consistent performance, ease of use, and a comfortable pumping experience.

What’s inside the kit

• 10 duckbill valves engineered to reduce backflow during expression
• 4 silicone membranes designed to support reliable suction power

Potential benefits for your pumping routine

Regular replacement of worn components can help maintain steady suction and efficient milk expression. The duckbill valves are intended to minimize milk backflow, while the silicone membranes aim to preserve suction strength throughout pumping sessions. This pairing is chosen to support a smoother cycle and consistent performance over time.

These parts are described as food-grade silicone and BPA-free, with a skin-friendly profile intended to be gentle during frequent use. The kit’s soft materials are designed to fit securely onto compatible pumps, helping to reduce the chance of loose connections or discomfort during pumping.

Compatibility, safety, and care

The kit is advertised as compatible with Spectra S1, S2, and 9 Plus models but is not the original Spectra product. To keep parts in top shape, clean them after each use and avoid aggressive scrubbing. Inspect for wear and tear and replace as needed to maintain performance.

• Cleaning tips: rinse with warm, soapy water and rinse again with clear water
• Care notes: avoid dishwashers and harsh brushes; handle thin tips gently
• Storage: dry completely before reassembling to prevent odor buildup

Real-life use scenarios

At home, in the office, or during travel, these replacement parts can support ongoing pumping routines by keeping components in working order. While they are not official Spectra parts, users report the kit can help maintain a familiar pumping feel when used as part of regular maintenance.
