Description Details

Restore the integrity of your espresso machine's critical connections with the genuine FLANGE GASKET - VITON (GREEN) (Part # L100/AG). This essential OEM sealing component is engineered using high-grade Viton, a synthetic rubber renowned for its exceptional resistance to extreme heat, steam, and chemical exposure commonly found in high-pressure espresso systems. If you are experiencing a "leaking boiler connection on your La Marzocco" or noticing "pressure loss around heating elements," this green Viton gasket offers the ultimate solution for maintaining a perfect, long-lasting seal. Its superior material composition significantly outlasts standard seals, minimizing the frequency of replacements and preventing costly downtime in high-volume commercial environments.

The Viton FLANGE GASKET (L100/AG) is designed to fit specific La Marzocco models, ensuring factory-level performance and pressure stability. Key features include the distinct green color for easy identification of the superior Viton material and precise dimensional specifications for flawless installation onto flanges and steam assemblies. Unlike typical rubber gaskets that degrade under high thermal stress—leading to common problems like "steam leaks at the group head flange"—this Viton seal maintains its flexibility and sealing strength up to 400°F. Investing in this genuine replacement part ensures reliable operation and protects internal components from the damage caused by intermittent leaks.

To use, ensure the contact surfaces are clean and free of scale before installing the new L100/AG gasket into the flange groove. This critical preventative maintenance step provides a robust solution for operators searching for a "high-temperature boiler gasket replacement" or an "espresso machine flange seal that resists chemical breakdown." Trust the durability of the OEM Viton material to guarantee consistent pressure, optimal temperature control, and maximum uptime for your La Marzocco machine, solving the persistent maintenance challenge of seal degradation.
