Silicone grease for espresso machines CX80 – lubricant for group seals and O-rings, 20 g tube

CX80 silicone grease for espresso machines is a food‑grade lubricant formulated to protect and prolong the life of group seals, O-rings and other rubber or silicone parts in domestic and professional espresso machines. Presented in a 20 g tube for targeted application, this silicone lubricant helps prevent drying, cracking and leaks around brew group interfaces and moving seals, supporting reliable extraction and consistent machine performance during routine maintenance and minor repairs.

Advantages

The silicone grease is food‑grade and safe for incidental contact with coffee equipment surfaces, and its neutral odor and stable consistency ensure clean application without affecting beverage taste. Supplied in a small, squeezable tube, it enables precise dosing for seals and O-rings, reduces friction between moving parts and helps maintain watertight connections. The formulation resists water washout and temperature variation typical of espresso machine environments.

Suitable for

• Lubricating group seals and portafilter gaskets
• Protecting and renewing O-rings on valves and fittings
• Maintenance of piston seals and other moving components in brew groups
• Minor repairs and preventive maintenance on domestic and commercial espresso machines

Key specifications

• Form: viscous silicone grease in a 20 g squeeze tube
• Food‑grade formulation suitable for incidental contact with coffee equipment surfaces
• Compatible with rubber and silicone sealing materials used in espresso machines
• Resistant to water washout and stable across typical espresso machine temperature ranges

How to use

Before application, switch off and depressurize the machine and allow components to cool. Apply a thin, even layer of silicone grease to clean, dry seals, O-rings and gasket contact surfaces; avoid excess that could migrate into the brew path. Reassemble parts and run a short water-only cycle to remove any surface residue if needed. For routine maintenance, reapply when seals show signs of drying, stiffness or minor leakage.

Usage recommendations

Use only a small amount to avoid contamination of brew water and follow manufacturer guidance for specific machine models; store the tube capped in a cool, dry place away from direct heat sources.
