ROK 50mm Portafilter for Manual Espresso Machines

Need a replacement portafilter for your ROK espresso machine, or want a spare ready for your next shot? This ROK 50mm portafilter is a fully assembled option made for ROK espresso machines. It pairs a chrome-plated, die-cast zinc body with a stainless steel filter basket sized for a double espresso dose of 16–19 grams of ground coffee.

What does a portafilter do?

The portafilter holds your ground coffee while you brew. Fill the basket, distribute the grounds evenly, tamp, and fit it into your machine. Water passes through the coffee to make your espresso. It is a simple part of the setup, but getting the dose and grind right here makes a real difference in the cup.

The details that matter

• 50mm size: Designed for ROK espresso machines.
• Double-shot basket: Suitable for 16–19 grams of ground coffee.
• Chrome-plated, die-cast zinc body: Supports the stainless steel filter basket.
• Fully assembled: A practical choice when replacing your ROK portafilter or keeping a spare on hand.

A straightforward starting point

Start with a dose within the 16–19 gram range and use an espresso-fine grind. Weigh your coffee so you can repeat the dose, distribute it evenly, and tamp before brewing. Keep the dose steady while adjusting your grind, rather than changing everything at once. That makes it easier to figure out what your coffee needs.

Will it fit my espresso machine?

This is a ROK 50mm portafilter for ROK espresso machines. Do not choose a portafilter by diameter alone: the way it locks into the machine matters too. If you are shopping for a different brand, check compatibility before ordering.
