Refresh the seal at the brew head with a red silicone E61 group head gasket sized for machines that use an 8 mm brew head seal. 73 mm outer diameter, 57 mm inner diameter, 8 mm thickness — a practical replacement for leaks around the portafilter, worn rubber, or a loose lock-in feel.

The red silicone E61 group head gasket is made for buyers who want a cleaner seal without changing the machine’s daily workflow. The beveled ring profile helps the portafilter seat firmly, while the silicone stays flexible through repeated heat cycles during espresso brewing.

Each gasket is packed as one piece in a simple protective pouch. The compact spare is easy to keep in a maintenance drawer, ship with a repair kit, or include with a home espresso upgrade order.

This is the 8 mm version of the gasket. Before ordering, confirm your machine uses an 8 mm brew head seal, and check the current gasket if the portafilter locks too far to the side or leaks under pressure.

Suitable for E61-style brew heads and compatible models that use the same 8 mm gasket size — including listed Gaggia, VBM, Faema E61/E98, and Decent machines. Always match the gasket thickness before installation.

Replace the gasket during routine cleaning when the shower screen is removed. It is a practical time to inspect the old seal, clean coffee oil from the groove, and fit the new gasket before reassembling the brew head.

Install the gasket into the clean brew head groove with the correct orientation, then lock in the portafilter to check the feel. A proper fit should feel secure without needing excessive force on the handle.

Choose a fresh gasket when water or coffee escapes around the portafilter, the old seal has hardened, or the handle no longer locks in its usual position. A new 8 mm gasket can restore a more stable seal for daily espresso use.
