Homemade Airlock Lids

How to make your own Airlock Lids


  • Tattler Plastic Lids (Amazon)
  • Silicone Rubber Grommets – food / dishwasher safe. Go to Zoro.com and search for “G1209476”. These are by far the best grommets I’ve found, others often break down in the dishwasher, these should last for years.
  • Drill
  • 5/8” drill bit


  • Take a tattler lid and gasket and screw on to mason jar with ring (or secure lid to drill press)
  • Carefully drill a 5/8” hole in the middle of the tattler lid. Clean burrs from hole.
  • Work grommet into lid hole
  • Clean out jar and wash
