IVARONAL 22mm Flange & Duckbill Valve Replacement Kit for Spectra S1 S2 S9 Plus & Synergy Gold Pumps

Upgrade your Spectra pumping experience with IVARONAL replacement parts

IVARONAL offers a thoughtfully designed replacement parts kit built to support reliable, comfortable expression across popular Spectra models. This set includes 2x 22mm flanges and 4x duckbill valves. It’s a versatile option designed for broad compatibility with Spectra S1, Spectra S2, Spectra 9 Plus, and Synergy Gold pumps. Note: these are third‑party replacement parts and not the original Spectra S2 Plus, S1 Plus, or S9 parts, but they’re crafted to work with common configurations and to replace worn components when needed.

In real-world pumping, comfort and steady performance matter. The 22mm flange size is a common fit for many users, featuring a soft, skin‑friendly silicone that feels gentle against the skin while forming a secure seal. The duckbill valves are designed to maintain a steady flow with minimal resistance, contributing to a smoother pumping rhythm. Together, these parts can help you maintain a comfortable fit and a consistent expression without sharp edges or stiff seams.

What you get

• 2 x 22mm flanges
• 4 x duckbill valves

Materials, safety & comfort

All components are made from food-grade silicone and are BPA-free. The material is soft, odorless, and skin-friendly, aiming to keep touchpoints pleasant during expressing sessions. While not medical-grade, the silicone is chosen to minimize irritation and support a comfortable pumping experience.

Easy to install and care for

Installation is straightforward—press the flanges onto the pump and attach the valves. The design helps prevent loose tubing and torn ends, contributing to a calmer pumping setup. Cleaning is simple: wash with mild soap, rinse well, and air-dry. Avoid dishwashers and harsh brushes; gently clean thin tips with fingers to keep them supple.

Maintenance, support & usage notes

Regular replacement of pump parts can help maintain efficiency and comfort. This kit is designed to work with Spectra S1, S2, Spectra 9 Plus, and Synergy Gold models, offering a convenient option when replacements are needed between original parts. If you have questions about fit or compatibility, the support team is available to assist and guide you toward the best setup for your routine.
