How to Choose the Right Stopper

A good stopper should seal well, be easy to clean, and fit the storage you already use.

  1. Check Compatibility: Confirm the stopper is made for your pouch or bag thread. This stopper is made for Haakaa Yummy Pouches and Haakaa silicone storage bags.
  2. Think Portability: Look for a carry loop or compact shape if you plan to take pouches to daycare, work, or errands.
  3. Consider Cleaning: Pick a stopper that can be sterilized and is dishwasher safe, or that tolerates boiling for quick sanitizing.
  4. Match Your Routine: If you pump into pouches, choose a stopper that seals tightly under gentle pressure and repeated use.
  5. Inspect Regularly: Check silicone for cracks or wear over time and replace the stopper if you see damage.
