An ABS to copper coupling is a plumbing fitting used to join together two different types of pipes: one made of Acrylonitrile Butadiene Styrene (ABS) and the other made of copper. ABS is a type of thermoplastic commonly used for drain, waste, and vent (DWV) systems, while copper pipes are often used for water supply lines.
The coupling is designed to provide a watertight and secure connection between the ABS pipe and the copper pipe. It typically has a hub or socket on one end to fit over the ABS pipe and a compression or solder connection on the other end to attach to the copper pipe.
These couplings allow for easy transition between different pipe materials and are often used when making repairs or modifications to plumbing systems, ensuring a smooth flow of water or waste through the connected pipes. When using ABS to copper couplings, it is essential to follow proper installation procedures to ensure a leak-free connection and maintain the integrity of the plumbing system.
