How to Replace Your Moka Pot Rubber Seals and Gaskets

  • Carefully remove all the rubber seals ONE BY ONE from your moka pot. Remember which seal goes where in the pot if your pot uses more than one, as the seals often have different sizes. If the seals are hard to remove, simply use a thin knife or a pair of tweezers to pull them out. Careful not to dent or bend the surrounding metal areas of the seal.
  • Clean the pot thoroughly as instructed in the Cleaning and Maintaining Your Moka Pot page.
  • Take your new replacement seals and wash them lightly with soap and water. Careful not to stretch or tear the seals. Towel dry when done.
  • Compare the new seals with the old one, match each seal so that you’ll know which seal goes to which section of your moka pot.
  • Install your new gaskets. In most cases, you won’t even need to stretch them much. Just attach and push down so the base of the rubber gaskets seat flush on the moka pot gaps.
  • Once you install all the new seals, assemble the pot lightly, making sure that the new seals aren’t pinched in between the metal parts, if everything checks out, try boiling some hot water only to test the seal.

That’s all there is to it in terms of replacing your moka pot rubber seals and gaskets. We also suggest that you ‘break in’ the rubber seals just to make sure the seals work by checking if steam and water leaks out when you brew a test pot of water before moving on to coffee.

The rubber seals in a moka coffee pot are the only parts that suffer from wear and tear, so as long as you keep the rubber seals and gaskets in good shape by replacing them periodically, your moka coffee pot will serve you well for a long, long time.

It is critical that your moka pot’s rubber seals are in good shape because your pot will lose pressure during the brewing process if they are worn out. The water and gases will leak and you will not be able to brew coffee at all.
