Professional Sealing Solution for Commercial Espresso Machines
The 73 × 57 × 8.5 mm Espresso Group Gasket is an essential replacement component that creates a secure seal between the espresso group and the portafilter during coffee extraction. Proper sealing ensures stable brewing pressure and contributes to consistent espresso quality.
Replacing worn group gaskets at the recommended intervals helps preserve the performance of the espresso machine while reducing unnecessary wear on other brewing components.
Premium NBR 85 Shore FDA-Approved Rubber
This gasket is manufactured from professional NBR 85 Shore rubber, approved for food contact according to FDA standards. The material combines excellent elasticity with outstanding resistance to heat, pressure and continuous commercial operation.
Its durable construction makes it suitable for demanding cafés, restaurants and other professional coffee environments.
Signs That the Gasket Should Be Replaced
Over time, exposure to heat and repeated brewing cycles causes the gasket to harden and lose flexibility. This may lead to water leaking around the portafilter, increased locking force or unstable extraction pressure.
Installing a new gasket restores proper sealing and helps maintain reliable espresso preparation.
