La Spaziale 6.7mm Group Head Gasket A slightly thicker (6.7mm vs. the standard 6.3mm) silicone group gasket for La Spaziale groups, purpose-built for groups with worn portafilters and/or group heads where the standard-thickness gasket no longer seals fully. La Spaziale part #09168. SPECIFICATIONS 64 x 52 x 6.7 mm Silicone rubber (longer-lasting and lower installation force than older rubber compounds) La Spaziale part #: 09168 COMPATIBILITY Fits: all La Spaziale group heads, especially those with worn portafilters or group heads where the standard 6.3mm gasket has gone too thin to seal Works with: paper shims for added height if needed INSTALLATION Simple DIY gasket swap. PRO TIPS If your portafilter has started engaging past the six o'clock position even with a fresh standard gasket, that's the sign to size up to this 6.7mm version rather than keep replacing the standard one, worn group/portafilter tolerances need the extra thickness to seal.
