The LARSEN SUPPLY CO., INC. 04-1821 is a replacement toilet tank flush lever designed to restore proper flush actuation on American Standard toilet tanks. The lever features a chrome-plated handle paired with a plastic arm, configured at a 22-degree angle to match the original mounting geometry. At 6 inches in length, it installs directly into the tank wall using the existing trip lever opening. This part is sold individually and is packaged on a card for retail or service-counter distribution. Plumbers and professional service technicians install this type of component as a direct OEM-style swap during tank repair or fixture refurbishment.
This flush lever is suited for residential toilet tank repair where the original trip lever has corroded, cracked, or broken. The chrome handle provides a finished appearance consistent with standard bathroom fixtures. The plastic arm reduces corrosion risk in the wet tank environment. Compatible applications center on American Standard toilet tanks originally equipped with OEM part 47191. Installation requires no special tools beyond basic hand tools and takes only minutes in a standard tank service call.
Direct replacement for American Standard toilet tanks originally fitted with OEM part number 47191.
Installation is typically performed by a licensed plumber or experienced service technician. Shut off the water supply valve at the base of the toilet and flush to empty the tank before beginning work. Remove the existing trip lever through the tank wall opening, install the 04-1821, and secure the mounting nut hand-tight before restoring water supply. Follow all applicable local plumbing codes, including IPC guidelines, for fixture repair and component replacement.
