The Maymom Pump Parts Compatible with Spectra S2 S1 Replacement Kit offers a practical and affordable solution for maintaining breast pump performance. This set includes a 21mm flange, duckbill valve, tubing, bottle, and backflow protector, designed to fit Spectra S2 and S1 models without being original Spectra accessories. The flange is made from firm yet comfortable medical-grade silicone, ensuring a reliable seal during use. The duckbill valve is crafted from flexible silicone to create consistent suction and prevent milk backflow, while the backflow protector effectively blocks moisture from reaching the pump motor. Each component is constructed with smooth, seam-free surfaces to simplify cleaning and reduce residue buildup. The bottle features clear BPA-free plastic with volume markings for easy measuring. All parts are compatible with standard Spectra connection points, allowing straightforward replacement without adapters. The kit provides a complete set for users who need a backup or replacement for worn components, helping maintain hygiene and pumping efficiency. The materials are selected for durability and repeated use, though they are not original brand parts. The kit offers a cost-effective alternative to official replacements, suitable for daily use at home or on the go. Users can expect consistent performance when combined with their existing Spectra pump. The components are designed to be disassembled quickly for thorough washing, supporting proper maintenance.

This replacement kit delivers practical utility for those seeking reliable pump parts at a reasonable price point.
