This replacement kit offers a practical solution for maintaining Spectra S1, S2, and S9 Plus breast pumps. The set includes two duckbill valves, a tube, a bottle, and a backflow protector, all designed as compatible non-original accessories. Each component is engineered to mirror the dimensions and fit of the original parts, ensuring seamless integration with the pump system. The 24-millimeter flange size accommodates a common standard, allowing for straightforward installation without additional adapters.

The duckbill valves are molded from flexible, food-grade silicone that provides reliable one-way flow control. This design helps prevent milk from flowing back into the tubing, supporting hygiene during pumping sessions. The included tubing is made from BPA-free PVC, offering durability and flexibility for repeated use. The backflow protector acts as a barrier to keep moisture and milk residue from reaching the pump motor, which can help extend the lifespan of the device.

The bottle features clear markings for volume measurement and is compatible with standard Spectra bottle caps. In terms of performance, these parts maintain steady suction and milk expression when used correctly. The silicone valves maintain their shape after multiple uses, and the tubing resists kinking under normal handling. The bottle is thick-walled and withstands repeated sterilization in boiling water or steam sterilizers without warping.

The backflow protector’s membrane seals effectively during suction cycles, reducing the need for frequent cleaning of the pump base. This kit represents an affordable alternative to original manufacturer replacements. The materials meet general safety standards for food contact, and the parts are designed for easy disassembly and cleaning. Users who need to replace worn or lost components will find this set offers a balance of cost savings and functional reliability.

The two-pack of duckbill valves provides a spare for rotation or backup, extending the interval between repurchases. Ideal for regular pumping routines, this kit suits parents who require dependable replacement parts without paying premium prices. Whether used for daily expression or occasional travel, the components deliver consistent fit and performance. Maintaining a clean and functional pump system is simplified with this comprehensive set, making it a practical addition to any Spectra pump owner’s supplies.
