Questions & Answers
Does this replace American Standard 33643-07 it measures 3 inch diameter and the specifications for FluidMaster shows more than 4 inches Wide? (Are these specifications for the package size?)

How does the 5103 flapper valve attach? I have a little screw but when I try and shove the rubber flapper valve over the screw and I try and lift the flapper to flush it keeps coming loose?
The 5103 is a snap on fit which uses a brass insert to screw onto the American standard flushing arm. Make sure that the American Standard arm is the correct set up for the 5103. For more information visit fluidmaster.com about installing this flapper.
Does this fit fluidmaster 400 (#m12511) ?
Worked exactly as expected and was really easy to install!
No it does not.
The question is a little confusing. There are two different devices in your toilet tank. The fluidmaster 400 is a (1) tank filler valve with a float that cuts off the water inflow, it does not incorporate a flapper (performs the same function as a 'disc'). Device (2) in your tank is a flushing device, which incorporates a flapper or disc. You do not have to match a flapper/disc with a particular filler design. The two separate devices can even be from different manufacturers. The hole in the center of the disc fits many toilet 'flapper' designs of the 'pecking chicken' type, these bob up and down, they have a have tube that fills with water. The water weight in the tube becomes a counterbalance that holds the disc open momentarily when you pull on the chain. The pecking chicken' type of disc in the picture will not work with a system that use a flexible plastic hanger harness, the 'hanger type' hangs on posts molded into the sides of the fill tube. In the hangar type there is no tube full of water, there is no center flapper hole, it has rubber straps. If you have the 'pecking chicken' type mechanism just measure the diameter of the fitting entering the center hole. Buy the disc, press it on, if it is snug, it fits. No tools needed. The little 'stiffening ribs' in the picture may be a problem. If you install the disc in the picture listen hard for a 'whispering' leak when it is closed. If it leaks, the disc is too stiff, if so, look for a softer disc without the stiffening ribs in the middle, and made of a softer and thinner rubber.
Does this replace the American Standard SEAT DISK 421BP?
It seems to fit all of my American Standard commodes.
It can snap on and if there is a screw the brass adapter will work. My problem was with the hardness of the rubber that wont conform to the outlet orifice.
