Description
The IPEX SCH 40 Hub DWV PVC Coupling is a 4-inch PVC fitting designed to join Schedule 40 drain, waste and vent pipe in household and commercial plumbing. You’ll reach for this coupling when you need a straightforward connection for DWV systems—whether tying into an existing run, completing a new riser, or making a clean repair on a sewer or vent line. The hub connection accepts standard 4" Schedule 40 PVC pipe and the PVC construction resists corrosion and common sewer-system conditions. Its simple, no-nonsense design keeps installations quick and predictable, fitting into common DWV layouts in basements, crawlspaces and utility areas. For plumbers and DIYers working on residential or light commercial drainage, this coupling provides a reliable way to extend or repair 4" PVC DWV lines.
