Fluidmaster Inc 641 Chrome Perfect Fit Tank Lever

Product Description

The FLUIDMASTER INC 641 is a chrome-finished, adjustable tank lever designed to replace worn or broken flush handles on residential toilets. The arm rotates to accommodate front, side, angle, and right-hand tank mount configurations, making a single part usable across a wide range of toilet styles. The length and angle of the arm adjust to achieve proper chain alignment with the flapper, reducing incomplete flushes caused by a misaligned connection. Licensed plumbers and skilled DIYers install this part as a direct OEM-style replacement with no specialty tools required.

The 641 fits most residential toilet tanks regardless of flush handle orientation. It is suited for standard gravity-fed tank toilets commonly found in residential bathrooms and light commercial restrooms. The rotating arm design eliminates the need to stock separate left-hand and right-hand levers, simplifying service calls where the original handle configuration is unknown. It is sold individually as a unit-of-measure single piece, with package quantities available in 10.

Installation Notes

Shut off the water supply at the angle stop valve below the tank before removing the existing lever. A pair of adjustable pliers is typically sufficient to loosen the mounting nut, which is usually reverse-threaded on standard tank levers. Rotate and adjust the arm to align with the flapper chain before tightening, then restore water supply and cycle the flush to confirm proper lift and chain slack. Follow local plumbing codes as applicable.
