PVC 3" Expansion Joint. PVC Pipe is designed for both above and below ground DWV (Drain, Waste, Vent) Applications. Also the pipe can be used for both commercial and residential plumbing construction. PVC and its fittings are glued together with special glue that's designed to create a seal that is leak proof and durable like the pipe. Because PVC is fairly rigid, this pipe is an excellent pipe choice for just about any application in the DWV category. This PVC 3" Expansion Joint is designed for connecting pipes in areas where space is limited, and where pipe is already installed and can't be moved. The Expansion Joint features a coupling that can slide up to 3 inches.
