Overview

Discover the NENESUPPLY 21mm two-pack flange set, designed as reliable replacements for your Spectra pumping setup. These wide-mouth flanges are crafted to be compatible with Spectra S2, S1, 9 Plus, and Synergy Gold breast pumps, offering a versatile option when you need fresh pump parts without sacrificing comfort or convenience.

Key benefits at a glance

• Two 21mm flanges per pack provide immediate replacement options.
• Wide-mouth design supports secure attachment with Spectra bottles and backflow protectors.
• Smooth angles and a 32mm+ tunnel length aim to reduce rubbing and improve pumping comfort.
• Interchangeable with Spectra valves and other compatible accessories for flexible use.

Comfort and design

The flange geometry emphasizes gentle curves and a smooth interior to minimize contact with the skin during pumping. A longer tunnel helps accommodate a range of nipple shapes, contributing to a more comfortable experience over longer sessions. While not original Spectra parts, the design prioritizes a secure seal and reliable performance with compatible components.

These flanges are intended as compatible replacements that align with Spectra S2, S1, 9 Plus, and Synergy Gold systems, including compatible Spectra valves, backflow protectors, and bottles. They also pair well with NENESUPPLY bottles, offering a wide-mouth option for users who value interchangeability across brands.

Care and safety

Designed for easy cleaning, the flanges are top-rack dishwasher safe and can be sterilized using boiling water, steam, or microwavable bags. They are BPA-free and DEHP-free, and comply with FDA guidelines for food-contact materials. Independent lab testing supports safety considerations inherent to the materials used.

Real-life use scenarios

Whether you’re traveling, managing a busy pumping schedule, or rotating parts at home, these 2-pack flanges offer a practical, compact option to keep pumping smoothly. The wide-mouth compatibility helps with quick bottle changes, while the comfortable design supports longer sessions without added strain.
