American Standard Ultima Diaphragm Assembly for Toilet Flush Valve 1.1 GPF - AMS-M954323

Yes. The Ultima diaphragm assembly is built to retrofit Sloan and Zurn diaphragm flush valves, so you can keep the existing valve body on the wall and just rebuild the working parts. That makes it a practical standardization choice when a building has a mix of American Standard, Sloan and Zurn valves on the same restroom group.

It is the toilet (closet) version, rated at 1.1 GPF. The application is toilet use, so do not put it in a urinal valve expecting the urinal flush volume. Kits in this family ship with the closet or urinal trip mechanism to match the valve they are rebuilding, and this one is the closet 1.1 GPF part, ordered as M954323-0070A.

Yes, that is a common water conservation move: the diaphragm is what meters the flush, so fitting the 1.1 GPF Ultima kit converts a higher volume closet flushometer down to 1.1 gallons per flush without replacing the valve. Confirm the bowl will carry waste at 1.1 GPF before converting a whole restroom, since older 3.5 gallon bowls were not designed around that volume.

More than the diaphragm. The kit is furnished complete with the closet trip mechanism, so the rebuild covers the seal and the tripping parts rather than just the rubber. You supply nothing beyond a wrench and the water shut off at the control stop.

The Ultima diaphragm kit is a chemical and clog resistant design, which is the reason to choose it in buildings with aggressive water treatment or grit in the line, where standard rubber diaphragms weep or hang open and run continuously.

Order American Standard M954323-0070A. It is the 1.1 GPF diaphragm assembly for a toilet flush valve, and there is one configuration, with no finish option to specify since the parts are internal to the valve.
