The COPPERFIT 1A1573 is a 3-inch threaded by slip (T x S) ABS DWV male adapter designed to connect threaded pipe ends to slip-fit drain, waste, and vent systems. Constructed from ABS plastic, this fitting provides a reliable, corrosion-resistant transition point within residential and light commercial drainage systems. At 0.29 pounds, it is lightweight and easy to handle during installation. Plumbers and pipefitters use this adapter when joining a male-threaded fitting to a socket-end ABS DWV line, making it a common component in new construction and drain system repairs.
This adapter is suited for residential and light commercial DWV applications where a threaded-to-slip connection is required. It is typically installed in drain, waste, and vent lines within walls, floors, or exposed utility spaces. The 3-inch size accommodates standard drain branch and main drain configurations commonly found in bathroom, laundry, and kitchen drainage rough-ins.
Designed as an OEM-style replacement or standard fitting for use in 3-inch ABS DWV piping systems.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off water supply and ensure the drain line is clear and dry before fitting. Use ABS-rated solvent cement on the slip end and appropriate thread sealant on the threaded connection. Do not over-tighten threaded connections, as ABS fittings can crack under excessive torque.
