Description
xEnhance your Spectra compatible pumping kit
Introducing the Nenesupply 21mm two piece set, pairing wide mouth flanges with duckbill valves. Designed to work with Spectra S2, S1, 9 Plus, and Synergy Gold pumps. These are not original Spectra parts, but they are crafted to fit and perform with your compatible system, offering a practical alternative for everyday use.
Comfort and fit are a primary focus. The flange funnels feature smooth angles that avoid rubbing against the nipple, and the tunnel length is at least 32mm to accommodate a range of nipple shapes. The wide mouth design helps with bottle alignment and reduces fiddling during pumping sessions, making the process smoother over time.
What you get
- 2 x 21mm wide mouth flanges
- 2 x duckbill valves
Performance and safety
- Duckbill valves are easy to install and remove while maintaining suction
- Constructed from food grade silicone and independently lab tested
- Top rack dishwasher safe; also suitable for boiling water, steam, and microwavable bag sterilization
- BPA free and DEHP free with FDA compliant materials for food contact use
Compatibility and care
Backflow protectors fit securely on the flanges and create an airtight seal, while bottles fit snugly on the flanges for a stable pumping setup. The parts are compatible with Spectra backflow protectors and Spectra bottles, and also work with Nenesupply bottles, offering flexibility for your pumping routine.
Real world use
These components are ideal for home sessions and travel alike. Having a backup set helps reduce downtime and ensures you can continue pumping even if OEM parts are not on hand. The design emphasizes comfort, reliable fit, and straightforward maintenance.
Care tips and ongoing maintenance
- Clean after use with warm soapy water and rinse thoroughly
- Place on top rack of the dishwasher or sterilize using boiling water or steam
- Inspect for wear and replace as needed to maintain a secure seal
