Keep your breast pump performing at its very best with this 2-piece replacement valve and membrane set. Designed for breastfeeding moms who rely on their pump every day, these spare parts are a simple, affordable way to restore optimal suction and prevent leaks — so you can focus on what matters most. These are breast pump accessories intended for external use as a pumping aid. They are not ingested or applied to the body as a cosmetic or supplement. Why Replace Your Breast Pump Valves & Membranes? Over time, the valves and membranes in your breast pump naturally wear out, leading to reduced suction, leaks, and an inefficient pumping session. Replacing them regularly is one of the easiest ways to maintain peak pump performance and milk expression efficiency. These replacement parts are compatible with Swing-style breast pumps (4 compatible models) and are made from durable, BPA-free-style plastic for reliable, worry-free use. Made in Mainland China.

Frequently Asked Questions Q: How often should I replace breast pump valves and membranes? A: It is generally recommended to replace breast pump membranes every 4–8 weeks with regular use, or sooner if you notice a drop in suction power or any visible wear and tear. Valves should also be inspected regularly and replaced when they appear cracked or stretched. Keeping fresh replacement valves and membranes on hand ensures your pump always performs at its best. Q: Which breast pump models are these valves and membranes compatible with? A: These replacement valves and membranes are designed to be compatible with Swing-style breast pumps, covering 4 compatible models. Please check your pump's model number against the product images before purchasing to ensure the correct fit. Q: How do I clean and maintain my breast pump replacement membranes? A: Rinse the membranes with clean water after each use. You can also wash them gently with mild soap and allow them to air dry completely before reassembling. Avoid boiling or sterilising plastic membranes too frequently, as this can cause premature wear. Always follow your breast pump manufacturer's cleaning instructions for best results. Q: Will worn valves and membranes affect my milk supply? A: While worn parts won't directly affect your milk supply, reduced suction from degraded membranes can make pumping less efficient, meaning you may not be fully emptying your breasts. This can indirectly impact supply over time. Replacing valves and membranes regularly helps maintain the suction needed for effective milk expression. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "How often should I replace breast pump valves and membranes?", "acceptedAnswer": {"@type": "Answer", "text": "It is generally recommended to replace breast pump membranes every 4–8 weeks with regular use, or sooner if you notice a drop in suction power or any visible wear and tear.
