Replacement Valve Reduces Leaks
After extended use, breast pump valves can begin to weaken. Replace a worn or damaged valve in your Philips Avent Comfort Breast Pump to allow milk to flow more easily from the pump into the bottle without leaks. Replace valves as needed to ensure your pump keeps working at peak performance.
Made from BPA-Free Materials
The valve, like all Philips AVENT breast pumps and components, is 100% BPA-free. To clean, rub the valve gently between your fingers in warm water with baby bottle washing soap.
