LESSO ABS FLUSH BUSHING - 4" x 2"Lesso ABS flush bushing reduces a larger drain-waste-vent (DWV) fitting hub down to a smaller ABS pipe in one short step. The spigot end slides into the larger fitting hub; the hub end accepts the smaller pipe. The interior bore is stepped so flow transitions cleanly without a ledge that would catch waste. Black ABS construction matches the rest of a standard residential DWV stack.
- Reducer size: 4" spigot x 2" hub
- Material: ABS plastic (DWV use, non-pressure)
- Connection: Spigot x Hub - solvent-weld both ends
- Color: Black
- Application: Drain, waste, and vent piping in residential and light commercial systems
Tip: Use ABS solvent cement (one-step black cement) for both joints - PVC cement and CPVC cement will not bond ABS reliably. Dry-fit first to check orientation, then clean both mating surfaces, apply a full ring of cement to the spigot and the hub socket, push together with a quarter turn, and hold for 30 seconds while the cement sets. Wait at least an hour before running water and 24 hours before pressure-testing any new section.
