Westlake Pipe Fittings dwv-d119-040 Dwv No-hub Adapter 4 in

Product Description

The WESTLAKE PIPE FITTINGS dwv-d119-040 is a 4-inch PVC no-hub adapter designed for drain, waste, and vent (DWV) piping systems. It connects hub to spigot ends, allowing a smooth transition between no-hub cast iron pipe and PVC DWV pipe in the same drainage run. The fitting is manufactured in white PVC for lightweight handling and corrosion resistance. Licensed plumbers and pipefitters install this type of adapter when joining dissimilar materials or extending an existing DWV stack. It is a straightforward, single-piece fitting with no gaskets or fasteners required beyond standard solvent cement on the hub end.

This adapter is suited for residential and light commercial DWV applications where a 4-inch nominal pipe size is required. Typical installations include drain stack tie-ins, horizontal branch connections, and transitions from underground cast iron mains to above-grade PVC runs. The hub end accepts solvent-welded PVC pipe, while the spigot end inserts into a no-hub coupling with a stainless steel band clamp. Plumbers working on new construction, renovation, or repair projects will find this fitting useful wherever a DWV pipe-to-no-hub transition is needed at the 4-inch size.

Key Features

• 4-inch nominal pipe size fits standard DWV drain, waste, and vent lines
• Hub x Spigot end configuration for solvent-cement-to-no-hub coupling transitions
• White PVC construction provides corrosion resistance and low weight
• DWV-rated fitting intended for gravity-flow drainage applications
• Single-piece design with no internal components to fail or replace

Compatibility

Designed as an OEM-style replacement or standard installation fitting for 4-inch residential and commercial PVC DWV piping systems requiring a hub-to-spigot no-hub transition.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off water supply and ensure the drain line is clear before cutting into an existing system. Use the appropriate PVC primer and solvent cement on the hub end per manufacturer and code requirements. The spigot end requires a no-hub stainless steel band coupling torqued to the coupling manufacturer specifications.
