Professional Espresso Group Gasket
The San Marco Espresso Group Gasket is a critical wear component that creates a secure seal between the espresso group head and the portafilter during extraction. A properly functioning gasket maintains brewing pressure, prevents water leaks and ensures consistent espresso quality throughout daily operation.
Manufactured in Italy from premium NBR 85 Shore rubber with FDA-compliant material, this gasket is designed to withstand the demanding conditions of professional espresso machines.
Reliable Sealing for Consistent Espresso Extraction
A tight seal between the group head and the portafilter is essential for stable brewing pressure. A worn, hardened or damaged gasket may cause water leakage, pressure loss and incorrect portafilter positioning, negatively affecting extraction quality.
Replacing the group gasket at regular service intervals helps maintain optimal espresso machine performance while protecting other components of the brewing group.
Premium NBR 85 Shore Rubber
The gasket is manufactured from professional-grade NBR rubber with a hardness of 85 Shore, offering excellent resistance to heat, pressure and long-term wear.
The FDA-compliant material is suitable for use in food and beverage preparation equipment, providing durability and reliable sealing in commercial coffee environments.
When Should the Group Gasket Be Replaced?
Replacement is recommended when:
- water begins leaking around the portafilter;
- the portafilter must be rotated excessively to lock into place;
- the gasket becomes hard, cracked or deformed;
- the espresso machine undergoes scheduled preventive maintenance.
