Get your replacement tubes for your Dr. Brown's Breast Pump with the Dr. Brown's Customflow Replacement Tubing pack. Pump tubing for a closed-system pump should never have lots of moisture, any milk, or have compromised integrity. It can make your pump suction worse or nonfunctional or damage the motor if the liquid travels. Get back to functional tubes and full pumping power with new tubes! Comes with (2) two pump tubes with connectors so your entire tubing system stays up to date. While tubes can be cleaned, follow all cleaning directions and do not use tubes until fully dried.
