Product Description
The KAIYIV Replacement Breast Pump Parts Set is specifically engineered for nursing mothers using compatible double electric breast pumps to maintain peak suction performance. This comprehensive bundle includes six premium duckbill valves and six flexible silicone membranes, providing an ample supply of essential components that naturally wear out over time. Regularly replacing these parts ensures efficient milk expression and protects your investment in your nursing journey.
Crafted entirely from high-quality, food-grade silicone, these components are completely free from BPA and completely odorless, ensuring maximum safety for both mother and baby. The duckbill valves are designed to facilitate a smooth, downward flow of breast milk directly into the collection bottle while preventing any reverse flow. Simultaneously, the durable silicone diaphragms preserve a tight, vacuum-sealed environment within the pump mechanism, eliminating leaks and drops in pressure. This set is an ideal choice for busy mothers seeking reliable, high-performance aftermarket parts that seamlessly match their daily pumping routines without compromising safety or comfort.
FAQ
Q1. Is the duckbill valve compatible with Spectra S1?
Ans: Yes, these replacement parts are fully compatible with the Spectra S1, S2, and 9 Plus breast pumps, offering an identical fit and function to maintain optimal suction performance.
Q2. Do Spectra S1 and S2 use the same parts?
Ans: Yes, the Spectra S1 and S2 models share the exact same internal mechanics for expressions, meaning these duckbill valves and silicone membranes work perfectly across both pump systems.
Q3. Can I pump without a duckbill valve?
Ans: No, pumping without a duckbill valve is not possible as the valve creates the essential vacuum seal required to generate suction and pull milk into the collection bottle.

Ans: Yes, Rudra Retails sources these authentic accessories directly from the USA, ensuring Indian mothers receive genuine, high-quality international personal care products delivered safely to their doorstep.
Q5. How often should I replace these pump accessories?
Ans: For optimal hygiene and performance, it is recommended to replace duckbill valves every four to eight weeks and silicone membranes every few months depending on your daily pumping frequency.
