Before buying clip lid glass jars or replacement rubber seals:

  • Glass jars with silicone gasket seals do not require any particular caution.
  • The natural rubber seals like the ones shown here will dry up, show cracks and break if kept in the jar when the latter is not used.
  • This is particularly true in countries with a hot climate or at least in summer time.
To protect your seals, you just need to remove them from the unused jar and put them in the fridge. ​As simple, and they can last years...

Buy your clip top hermetic canning glass jar rubber gaskets here:

  • Replacement rubber seals (gaskets) are widely available for clip top lid jars.
  • Both natural rubber and silicone canning jar gaskets can be used.
  • Two sizes are available, regular mouth jars and wide mouth jars. Measure the diameter of your glass jar before ordering replacement gaskets.
