La Marzocco Kalrez® O-Ring for Paddle Group A Kalrez® center-portion o-ring for the La Marzocco paddle group, replacing the older H.1.011 (H.1.011.01) part. Kalrez® is a premium perfluoroelastomer that Nuova/La Marzocco specifies here because it holds up far longer than the standard rubber compound it replaces, up to four times the service life in this application. SPECIFICATIONS Part #OR 02037 (OR 0110) Kalrez® compound Sold individually, three o-rings used per group, center portion COMPATIBILITY Fits: La Marzocco paddle group Replaces: H.1.011, H.1.011.01 INSTALLATION Straightforward o-ring swap for a technician during a paddle group rebuild. PRO TIPS Each group uses three of these o-rings in the center portion, order in multiples of three rather than one at a time if you're doing a full paddle group service.
The catalog often lists the same model at several merchants — worth a price check before you buy.
