A small piece of rubber you never think about — until it wears out. That's exactly when an original replacement is worth its weight in gold, so your Comandante runs like new again.
This is the original rubber O-Ring as a replacement part for the Comandante C40. A typical wear part that can give way over time. Keeping a few original spare parts on hand keeps your hand grinder ready to use for years — in the spirit of a grinder built to last a lifetime.

From our roastery: a well-maintained grinder is half the battle for great coffee. Freshly ground, full-bodied profiles like Cozy Chocolate and Nutty Delight taste best, our recommendation for the vast majority. If you're after fruit, try Wild Peach. That's our recommendation, one of many.
