51 mm Group Head Seal for Older Breville Machines

The group seal is the soft ring the portafilter presses against. On 51 mm Breville machines it slowly hardens from heat, and the first sign is usually coffee running down the outside of the handle or the portafilter turning further than it used to.

Soft Silicone That Lasts

This replacement is moulded in clear silicone, which stays flexible longer than the original rubber. Supplier measurements are about 58 mm outside, 42 mm inside and 7 mm thick, so compare it with the seal you pull out.
