Rough-In to Finish, Sealed
ABS trap adapter that takes a drain run from rough-in to finish under a sink — the hub solvent-welds to the 1½" ABS wall stub, and the threaded spigot accepts the included plastic slip nut and washer to seal onto a P-trap or tailpiece. That slip-joint outlet is the connection that lets you tighten by hand onto a chrome, PVC, or brass tubular tailpiece and break it apart again for service without tools or cement. It's the standard way to land a finished trap onto an ABS rough-in. A LESSO America ABS DWV fitting conforming to ASTM D2661 and CSA B181.1 with NSF/ANSI 14 and cUPC listings. Stocked in 1½" and a 1½"×1¼" reducing size for lavatory tailpieces. DWV service only; test hydrostatically, never with compressed air or gas.
