A Reducer PVC Schedule 40 DWV 3 in. x 2 in. is a plumbing fitting designed to connect a 3-inch pipe to a 2-inch pipe in a Drain-Waste-Vent (DWV) system. It helps manage changes in pipe diameter while maintaining proper flow and drainage in residential or commercial plumbing. Made from durable Schedule 40 PVC, it resists corrosion and chemical damage, making it ideal for long-term indoor and outdoor use. The fitting typically features hub (socket) ends that are solvent-welded to ensure a leak-proof connection. It meets ASTM D2665 standards and is commonly used in gravity-fed wastewater and vent systems.
