This replacement parts kit is designed for use with Spectra S1, S2, 9 Plus, and Synergy Gold breast pumps, offering a practical alternative to original components. The set includes a 21mm flange, duckbill valves, tubing, bottles, and backflow protectors, all crafted to match the fit and function of the original accessories. Each piece is made from food-grade, BPA-free materials that meet safety standards for contact with breast milk. The flange features a smooth interior surface to ensure comfortable fit and efficient milk expression, while the duckbill valves are precision-molded to create a reliable seal that prevents backflow and maintains suction consistency. The tubing included in this kit is flexible yet durable, resisting kinking and collapsing during use.

It connects securely to the pump and bottle assembly, facilitating steady milk transfer. The backflow protectors are designed to shield the pump motor from moisture, extending the lifespan of the device. Components are easy to clean and can be sterilized using standard methods such as boiling or steam bags, supporting repeated reuse without degradation. The 21mm flange size suits many users, though compatibility should be verified against personal pump specifications. Construction quality is consistent across all parts, with no sharp edges or rough seams that might cause irritation.

The plastic parts are lightweight and resistant to cracking under normal handling. The duckbill valves have a soft, flexible silicone tip that opens and closes reliably with each pumping cycle, contributing to efficient milk flow. The bottles feature standard neck threading, allowing them to be used with most Spectra pump bottle collars and nipples. This kit serves as a reliable backup set for travel or daycare, or as a replacement for worn out original parts to restore pump performance. Priced competitively, this kit presents a very affordable option compared to purchasing each component individually or buying official replacements.

It delivers equivalent functionality without the brand premium, making it a smart choice for budget-conscious pump users. The parts are packaged compactly for convenient storage. Regular inspection and timely replacement of valves and flanges can help maintain optimal pumping efficiency over time. The materials are free from common allergens like latex and phthalates, adding to user peace of mind. This set is a comprehensive solution for maintaining the hygiene and performance of Spectra breast pumps.

Its design focuses on ease of use, reliable fit, and long-lasting durability. Users seeking a cost-effective way to keep their pump in good working order will find this kit suitable for regular use. The components are interchangeable with existing Spectra parts, allowing seamless integration into the pumping routine. With proper care, these replacement parts provide consistent service throughout their intended lifespan.
