A compact hub × FIPT adapter for clean, threaded transitions in ABS DWV runs. Solvent-weld the hub to Schedule-40 ABS, then use the female NPT (FIPT) end for compatible male pipe-thread connections—ideal when a threaded trap arm or cleanout is required. Built for non-pressurized drain/vent service and aligned to ASTM D2661 / CSA B181.1 with standard cUPC listings. (Nut not included—this is FIPT, not a slip-joint style).
