Spud Coupling Assembly: Fits Sloan Brand, For Royal(R), 3/4 in Size, Brass

Toilet flush-valve spuds, spud couplings, and friction rings form a water-tight connection between a flush valve (flushometer) and a toilet. Spuds are fittings with one end for attaching to a fixture's mounting hole and another end for attaching to a spud coupling at the base of a flush valve. Spud couplings connect the base of the flush valve to the spud fitting in the toilet mounting hole. These spuds and spud couplings are used as replacements for parts that have cracked, corroded, or no longer seat properly due to stripped threads. The friction rings are gaskets that seal spuds and spud couplings to prevent leaks. They're used as replacements for deteriorated rings that have started to leak.
