Complete Guide to Moka Pot Gasket Sizes

Use this tool to find the correct gasket for your Bialetti Moka Pot.

Introduction

Proper maintenance of your moka pot will extend its life and keep your coffee tasting great. A part of moka pot maintenance is changing out the gaskets on a regular basis. Your moka pot will not work well (or at all!) if you use an old or improper sized gasket. The good news? Cupper’s Coffee & Tea has connected people to Bialetti products for more than 30 years. We carry a solid range of Bialetti gaskets for several models, styles and sizes. We also have a range of Grosche products as well. 

How to Measure a Moka Pot Gasket

Before buying any gasket for your moka pot, it’s critical to be sure you have the right size. To measure your gasket, start with a ruler and compare your gasket to the chart below. We’ve linked the gasket info below to our store to make online ordering in Canada easy for you. While you’re at it, check out our huge fresh roasted coffee collection.
