American standard used some fluidmaster ballcocks but the were not the normal 400 model. Anyone else see these? I was curious what model number that style was. The float did not travel straight up and down,the float would travel on an arch.
 
Thanks. No, don't see them here. Or not yet anyway. It's a later model with the .com cast into it.

Why the the heck would they make this? Their bread and butter valve covers about every tank scenario I can think of. Compact and out of the way of the other workings.

Some sort of experimental run to get ready to change the whole line? Headscratcher...
 
Don't mean to resurrect an old thread but this strikes my curiosity and I have a few guesses. First of all, does anyone know what model Amstd that is? Perhaps the OP can chime in. From that picture it appears as though it's set to a fixed water level? At least I can't see any way to adjust it from here. If that IS the case then I can see them doing this for ease of installation and to prevent water level tampering. It probably still uses the same old Fluidmaster seal that were accustomed to.

I don't remember what model American standard tank it was in.
 
Perhaps they made it because the design uses fewer or less-expensive parts, or requires less labor, to make.
