Philips AVENT Comfort Breast Pump Valves, 4 Count;

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. The valve, like all Philips Avent breast pumps and components, is 100 percent BPA-free. To clean, rub the valve gently between your fingers in warm water with dish soap.
