Bases and Mounting Hardware

Keep your Dometic MasterFlush 7640 pedal-operated macerator toilet running strong with genuine bases and mounting hardware. As one of the only pedal-flush macerating toilets ever made for RVs, the 7640 remains a favorite in luxury motorhomes, diesel pushers, and premium fifth wheels — and with the model now discontinued, replacement parts are more important than ever to keep it in service. Shop genuine bases, floor mounting kits, and hardware built specifically for the Dometic MasterFlush 7640 toilet, so you can keep your coach's original pedal-flush macerating system running reliably for years to come.
