Same-Size Joins, Code-True DWV
ABS hub coupling for joining two same-size ABS DWV pipes in a clean, solvent-welded run — the everyday connector that extends a line or repairs a cut without a transition fitting. Both ends are hub sockets sized for Schedule 40 IPS ABS, so the pipe seats fully before the cement sets and the joint reads straight. The coupling meets ASTM D2661 and CSA B181.1 and carries cUPC certification, which is what an inspector looks for on a residential or light-commercial drain, waste, and vent rough-in across the GTA. ABS stays light enough to handle overhead on a ladder and rigid enough to hold alignment once the run is supported. Stocked in 1½", 2", and 3" for the sizes that cover most sink, tub, and branch-line work — a low-cost fitting you buy by the handful and never think about again because it simply holds.
Features
- Hub × hub sockets — solvent-weld two same-size ABS pipes into one continuous DWV run
- Schedule 40 IPS sizing — pipe seats to full socket depth for a joint that holds alignment
- ASTM D2661 + CSA B181.1 compliant — meets Canadian DWV code for residential and light-commercial
- cUPC + NSF/ANSI 14 certified — the listings inspectors check on a rough-in
- Lightweight ABS — easy to handle overhead and faster to install than metal or cast
- Three stocked sizes — 1½", 2", and 3" cover most sink, tub, and branch-line joins
- DWV service only — not for pressure; never test with compressed air or gas
