Marketing InformationThe PVC DWV p-trap features a union joint and hub x hub connection. The p-trap provides a water seal so that wastewater will automatically be trapped in the arc of the configuration, thereby preventing unwanted gases from entering the household environment. Polyvinyl chloride (PVC) is the most frequently specified of all thermoplastic materials because of its light weight, durability and cost-effectiveness. PVC DWV is easy-to-install and is joined by solvent cementing or threading. PVC fittings exhibit high corrosion and chemical resistance and will not rust, scale, pit or corrode. NIBCO® plastic fittings are backed by a 5 years limited warranty. Because of its longstanding reputation for innovation and precision in design and manufacturing, NIBCO® is the preferred brand in the industry.
