If this product is out of stock, consider the Caffewerks 8.5mm silicone gasket.
This is a replacement group gasket for E61 machines, including Quick Mill, Izzo, Rocket, ECM, Lelit, and Profitec brands. Even after routine cleaning, Clive recommends replacing the group gasket and screens once a year to create the best-tasting espresso.
We strongly recommend installing your group head gasket with Molykote Dow-111 Food-Safe Lubricant.
