Willow 360 Flextube Set: Replace Tubing and Dry It Right

The 90-day replacement rule for Flextube tubing

The Flextube is the milk path on your Willow 360 pump, carrying milk from breast to bag during every session. Because it handles milk directly, it needs regular replacement. Willow recommends replacing the Flextube every 90 days, or sooner if you notice discomfort or signs of wear. Mark the date you start using a new set so you don’t lose track.

A 2-pack gives you a spare, which is handy when one set is drying or in the dishwasher. Rotating between two sets also means you’re never caught without a clean tube.

Why moisture in the tubing matters

Moisture inside the Flextube can affect pump performance and milk safety. If you notice water droplets or condensation after cleaning, the tube isn’t fully dry. Using a wet tube may lead to weak suction or milk residue buildup. Always make sure the tubing is completely dry before your next pumping session.

How to dry pump tubing after washing

After washing your Flextube (by hand or in the dishwasher), follow these steps to dry it thoroughly.

1. Shake out excess water: Give the tube a few firm shakes to remove as much water as possible.
2. Hang to air-dry: Hang the tubing vertically with both ends open so air can circulate. Avoid leaving it in a closed container while damp.
3. Check for moisture: Before use, inspect the tube by holding it up to the light. If you see any droplets, continue air-drying.
4. Avoid using heat: Do not use a microwave or oven to dry the tubing, as high heat can damage the material.

Storing spare Flextube sets

Keep your spare Flextube set in a clean, dry place away from direct sunlight. A resealable bag or a dedicated pump bag pocket works well. Make sure the tubing is completely dry before storing to prevent mold or bacteria growth. Label the storage date so you know when the 90-day clock starts.

Signs it’s time to replace your Flextube sooner

Even before 90 days, replace the tubing if you notice any of these:

• Visible wear or cracks: Inspect the tubing for small tears or stiffness.
• Persistent moisture: If the tube stays damp despite proper drying, it may be time for a new one.
• Discomfort while pumping: Any unusual sensation during pumping could indicate a worn part.
• Weak suction: If suction seems weaker than usual, check the Flextube for blockages or wear.
