Fitment answers
Does universal mean it fits Gerber toilets?
No. Fluidmaster explicitly excludes Gerber toilets from this gasket's fit.
Are tank bolts included?
No. This package contains one gasket only; mounting hardware is sold separately.
What toilet style does it fit?
It fits most close-coupled two-piece toilets with a 2-inch flush valve and a round or hex-shaped flush-valve nut.
How do I verify the flush-valve size?
Turn off the water, separate the tank only if safe to do so, and identify the valve outlet or existing gasket size. Do not choose from brand name alone.
