This Valterra flush bushing steps a 1-1/2" hub connection down to a 2" spigot, letting you tie together drain-waste-vent (DWV) plumbing runs that don't share the same pipe size. It's a small, purpose-built fitting for adapting waste lines without cutting and re-piping a whole section.
Standard DWV-style construction means it solvent-welds in like any other fitting in your waste plumbing, and its compact size keeps it out of the way in tight underbelly runs.
Double check your existing pipe sizes before ordering so the hub and spigot ends match what you're tying into.
