The COPPERFIT 1A1512 is a 4-inch ABS DWV female adapter designed to transition between spigot (S) and threaded (T) connections in drain, waste, and vent piping systems. This fitting allows a plain-end ABS pipe to connect to a female-threaded fitting or male-threaded component, making it a practical solution for joining dissimilar connection types within a DWV assembly. At 0.57 pounds, the adapter is lightweight and straightforward to handle during installation. Plumbers and pipefitters working on residential and light commercial drain systems will find this adapter useful wherever a spigot-to-thread transition is required.
This adapter is suited for residential and commercial DWV applications including drain lines, waste stacks, and vent piping. It is typically installed where ABS pipe terminates at a threaded fixture, cleanout, or transition point. The 4-inch size is common in main drain lines and larger branch drain runs. This fitting is appropriate for use in above-ground and in-wall DWV configurations where ABS plastic pipe is the specified material.
Designed as an OEM-style replacement and standard-fit component for 4-inch ABS DWV piping systems in residential and commercial drain, waste, and vent applications.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Before beginning work, ensure all flow to the affected drain line is stopped and the line is clear of standing waste. The spigot end requires proper ABS solvent cement applied per manufacturer and code guidelines. Thread connections should be sealed with PTFE tape or an approved pipe thread sealant rated for DWV service.
