Toto THU340#PN Aquia Dual Flush Push Button Assembly 53mm Polished Nickel

The TOTO THU340#PN is the OEM replacement dual flush push button assembly for the TOTO Aquia MS654 one-piece toilet series. Finished in polished nickel, this 53mm spare part restores proper flush operation while maintaining a sleek, contemporary appearance on the tank lid.

The dual flush actuator provides two flushing options — a reduced flush for liquid waste and a full flush for solid waste — helping conserve water with every use. The button mounts directly through the standard 53mm tank lid opening with a simple twist-and-lock installation requiring no special tools.
