Nenesupply 30mm Flanges (2 Pack) for Spectra S2/S1 & Synergy Gold

Enhance Pump Comfort with Nenesupply 30mm Flanges

This 2-pack of 30mm wide-mouth flanges from NENESUPPLY is designed to pair with Spectra S2, S1, the 9 Plus, and Synergy Gold breast pumps. While these are not original Spectra parts, they’re crafted to integrate with the common Spectra ecosystem—working with compatible valves, backflow protectors, and bottles, including Nenesupply bottles. Each kit includes two large 30mm flanges, ready to refresh your pumping setup with a focus on fit and ease of use.

Comfort and design that feel right

These flanges are built with smooth angles and a flange tunnel of at least 32mm, aiming to minimize rubbing during pumping. The 30mm size is described as a comfortable option for a variety of nipple shapes, including some stretched varieties. The wide-mouth silhouette supports straightforward alignment and a stable seal, helping you maintain a confident rhythm through sessions.

Compatibility and versatility

• Wide-mouth flanges are compatible with Spectra valves, backflow protectors, and bottles, and can also be used with Nenesupply bottles.
• Designed as replacement-style parts that fit within the Spectra ecosystem, without claiming to be original Spectra parts.

Care, safety, and quality

• Dishwasher-safe (top rack) for convenient cleaning; can be sterilized by boiling water, steam, or microwavable bags.
• BPA-free and DEHP-free; FDA-compliant for food-contact materials and backed by independent lab safety testing.

Design details that matter

• Not original Spectra S2 flanges, but engineered to work reliably within the Spectra-compatible setup.
• Long tunnel and smooth interior aim to reduce friction, supporting comfortable pumping across longer sessions.
• Available in a range of sizes beyond 30mm to help you explore your best fit in real-world use.

Real-world use scenarios

Whether you’re managing a hectic morning routine or packing a pump for travel, these flanges offer a practical upgrade. Expect a stable, comfortable fit, simpler transitions between bottles and parts, and a setup that aligns with everyday mom-and-baby routines.

Tips for finding your best fit

When choosing flange size, prioritize comfort. If you notice rubbing or uneven suction, consider trying a different size (e.g., 27mm or 24mm) to evaluate seal quality and pumping rhythm. A short test session can help you decide what works best for you.
