American Standard Glenwal Toilet Tank Cover 4098 White - AMS-735083-400

It is the cover for the American Standard Glenwal 4098, a wall-mounted, back-outlet, close-coupled flushometer-tank toilet with an elongated bowl. Tank lids are model-specific castings, so match the 4098 model number stamped inside the tank or on the china rather than going by size or looks.

No hole in the cover. The 4098 uses a side-mounted chrome metal trip lever, so the handle passes through the tank body, not the lid. If the toilet you are matching has a top-mounted push button or top handle, it is not a Glenwal 4098 and this cover is the wrong part.

The 4098 is a pressure-assisted siphon jet toilet with a close-coupled flushometer tank, which means the tank holds a sealed pressure vessel rather than open water. The lid is made for that tank, so it seats over the vessel correctly. A gravity-tank lid of similar footprint will not.

White is the only finish this cover is made in, under American Standard part number 735083-400.020. For a property with several Glenwal fixtures, that one number covers every 4098 tank in the building.

Look for the giveaways on the fixture: it hangs on the wall with the outlet going back through the wall, the bowl is elongated, the tank sits directly on the bowl with the trip lever on the side, and the flush is pressure-assisted (a loud, sharp flush, not a gravity swirl). The tank and bowl join with American Standard's Speed Connect coupling. Those four together point to the 4098.
