The Barrier part for Standard Freemie Collection Cups is durable and protects your pump. It must be replaced if damage occurs. Inspect this important part before/after each pump session for any damage.
If you are experiencing a loss of suction, be sure to follow the proper assembly instructions by placing the barriers onto the backs of the breast flanges first. See instructions below for details.
