Rancilio Commercial Group Head Rebuild Kit Everything needed to refresh a Rancilio commercial group head in one kit, gasket, screen, screw, and the stainless dispersion nut. This fits any current Rancilio commercial solenoid-operated group. COMPATIBILITY Fits: any current Rancilio commercial solenoid-operated group head Replaces: group head gasket R_17 (OEM 36301046), group head screen R_39 (OEM 40200005), group head screw R_49 (OEM 37030518), and stainless dispersion nut R_402 (OEM 25139001) INSTALLATION A shop-standard job for a coffee technician, pull the dispersion screen assembly, swap all four parts together, and reseat. PRO TIPS Replace all four parts as a set even if the gasket looks like the only thing leaking, a scaled-up dispersion nut restricts water flow and can cause channeling that gets blamed on the pump or boiler instead of the actual culprit. Wipe down the group face and inspect for pitting before installing the new gasket; a pitted group face will chew through a new gasket just as fast as the old one.
The catalog often lists the same model at several merchants — worth a price check before you buy.
