Description

La Marzocco Viton O-Ring 1.78 × 7.65 mm – 75 ShA

The La Marzocco H.1.027 is a small Viton O-ring used as a sealing component in selected steam wand and hot-water assemblies. Measuring 1.78 × 7.65 mm, it is designed for applications where the H.1.027 seal is specified in the machine parts diagram.

A worn, damaged or hardened O-ring can compromise the seal around the relevant steam or hot-water connection. Replacing it with the correct size and material helps restore the assembly to the intended fit.

H.1.027 appears in La Marzocco parts diagrams for selected Linea Micra, Linea Mini R, GS3, GB5 X/S, KB90, Leva and Strada assemblies. Compatibility can vary by machine configuration and production version, so confirm the H.1.027 part number against your machine diagram before ordering.

When servicing steam or hot-water components, ensure the machine is switched off, fully cooled and depressurised before installation.

    Coffee Parts Thoughts:

    A small but important service seal where getting the exact dimensions and part number right matters. Match H.1.027 against the machine parts diagram rather than relying on the model name alone, particularly where steam wand assemblies have changed between production versions.
