The FLUIDMASTER INC 642 is a brushed nickel toilet tank lever designed to replace worn or broken flush handles on a wide range of residential toilets. The arm rotates to adjust its angle, allowing a single lever to fit front-mount, side-mount, angle-mount, and right-hand-mount tank configurations. The mounting nut and arm length are also adjustable, so the lever seats properly without modification to the tank. Licensed plumbers and experienced DIYers install this lever as a direct OEM-style replacement during routine toilet service or remodel work.
The 642 is suited for residential toilet tank applications where the existing lever has corroded, broken, or no longer actuates the flapper chain reliably. Its universal design covers the majority of standard toilet tanks encountered in the field. The brushed nickel finish coordinates with common bathroom fixture finishes. Compatible models named by the manufacturer include Mansfield, Kohler Wellworth, Eljer, and American Standard toilets, making it a practical stocking item for plumbing service trucks and supply rooms.
Direct replacement for toilets by Mansfield, Kohler Wellworth, Eljer, and American Standard. Universal design fits most toilets with a front, side, angle, or right-hand tank mount configuration.
Installation requires no special tools beyond a wrench to tighten the mounting nut inside the tank. Shut off the water supply and flush the tank before beginning work to allow access without overflow. Rotate the arm to the correct angle before securing, and verify the chain connection to the flapper allows a full flush stroke with minimal slack. This work is typically performed by a licensed plumber or experienced DIYer following local plumbing code requirements.
