Reduce cleanly. Keep code happy.
Compact and precise, this flush bushing slides a spigot end into a fitting hub to create a space-saving reduction in ABS DWV lines. It’s purpose-built for non-pressurized drain, waste & vent service and follows ASTM D2661 / CSA B181.1 conventions; ABS DWV fittings are typically cUPC-listed with required body/hub markings.
Features
