American Standard Top-of-tank Actuator, Dual Flush - AMS-7381092-202

The 7381092-202 top-of-tank actuator is built for the American Standard 4519A-900 tank. It's the rectangular push button that mounts through the tank lid and drives the dual flush valve. If your tank is a different American Standard model or another brand, this button won't line up with the valve stem, so match the tank model before ordering.

If the flush valve still seals and only the button is sticking or cracked, the top-of-tank actuator is the part to replace. It's the push button assembly and bracket that sits in the tank lid, not the flush valve itself. On an American Standard 4519A-900 tank, the 7381092-202 actuator drops in with its own tightening nuts, which is a lid-off, five-minute job rather than draining and pulling the valve.

Dual flush. The 7381092-202 is a two-stage rectangular push button, so it drives both the reduced and full flush volumes on the 4519A-900 tank. A single flush actuator has one button and will not operate both stages, so don't substitute one for the other.

Chrome is the only finish for the 7381092-202 actuator, ordered as MPN 7381092-202.0020A. For a property manager standardizing restroom hardware across a building, that keeps the look consistent but leaves no matching option if the rest of your trim is brushed nickel or matte black.
