The COPPERFIT 1A1511 is a 3-inch ABS DWV female adapter designed to connect ABS drainage, waste, and vent piping using a solvent-weld socket (S) inlet and a threaded (T) outlet. This fitting transitions between a plain-end ABS pipe and a female-threaded connection, allowing plumbers to integrate threaded fittings or cleanout plugs into an ABS DWV system. Weighing 0.37 pounds, the adapter is lightweight and straightforward to handle during rough-in work. It is suitable for use in gravity-flow drain, waste, and vent applications where a reliable, leak-free joint is required.
This adapter is used in residential and light commercial plumbing systems where ABS pipe is the specified material. Common install scenarios include connecting a threaded cleanout plug, transitioning to a threaded trap arm, or tying into an existing threaded fitting within a drain or vent stack. The 3-inch size fits standard 3-inch ABS DWV pipe and is appropriate for main drain lines, closet flanges, and horizontal branch drains in new construction or retrofit work.
Designed as an OEM-style replacement and standard fitting for 3-inch ABS DWV piping systems in residential and light commercial plumbing applications.
Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local code. Shut off water supply and ensure the drain system is depressurized and empty before cutting into existing lines. Use ABS solvent cement rated for the socket end and apply per the cement manufacturer's instructions, allowing full cure time before restoring flow. Do not use PVC cement on ABS fittings.
