Fluidmaster Inc 640 White Perfect Fit Tank Lever

Product Description

The FLUIDMASTER INC 640 is a white, universal toilet tank lever designed to fit a wide range of toilet configurations, including front, side, angle, and right-mount installations. The arm rotates and adjusts in both length and angle, eliminating the guesswork common with fixed-position levers. This lever serves as a direct OEM-style replacement for worn or broken flush handles and is typically installed by plumbers or experienced DIYers during routine toilet maintenance or repair. It ships as an individual unit and carries a 3-year warranty from the manufacturer.

The 640 is suited for residential toilet tank applications where the existing lever has failed or does not provide a proper fit. Its adjustable arm design makes it particularly useful in situations where standard fixed levers cannot achieve the correct alignment with the flapper chain or flush valve. The lever is compatible with right-handed tanks, which are often overlooked by non-universal replacement parts. Confirmed compatible replacements include Mansfield, Kohler Wellworth, Eljer, and American Standard toilets as stated by the manufacturer.

Installation Notes

Tank levers are typically installed by a licensed plumber or experienced DIYer. Before beginning, shut off the water supply at the angle stop valve below the tank and flush to empty the tank. Remove the old lever by loosening the mounting nut inside the tank, noting that the nut is often reverse-threaded. After installing the new lever, adjust the arm position and chain length to ensure a clean, complete flush before restoring water supply.
