LESSO ABS Flush Bushing — Spigot × Hub DWV, cUPC Certified

ABS flush bushing for reducing pipe size inside an existing fitting hub — the spigot end carries the same outside diameter as pipe, so it drops straight into a hub and saves the space a separate reducing coupling would need. It's built for non-pressurized ABS drain, waste, and vent work and meets ASTM D2661 and CSA B181.1 with cUPC certification, the listing an inspector checks on a residential or light-commercial rough-in across the GTA. One-step black ABS cement bonds the joint with no primer, and the low-profile body keeps the reduction tight where a coupling won't fit. Stocked in 2×1½", 3×1½", and 3×2" — the reductions that come up most often when a branch or fixture line meets a larger fitting mid-run.
