Plastic Trends d308-4 Pvc Dwv Sch 40 Wye 8x4 Inch

Product Description

The PLASTIC TRENDS d308-4 is a fabricated PVC DWV wye fitting designed for drain, waste, and vent piping systems. Built to Schedule 40 specifications, this wye connects an 8-inch main line to a 4-inch branch line, allowing smooth directional flow transitions in sanitary drainage layouts. The Schedule 40 wall thickness delivers the rigidity required for buried and above-slab residential and light commercial drain installations. Licensed plumbers and pipefitters rely on this type of fabricated fitting where standard molded fittings are not available in the required size configuration.

This wye fitting is suited for residential and light commercial DWV applications where a reduction branch off a large-diameter main drain run is required. Typical scenarios include main stack transitions, horizontal drain manifolds, and building drain connections where an 8-inch main must accept a 4-inch branch. The fitting is compatible with standard PVC DWV pipe cement and primer joining methods as defined in applicable plumbing codes.

Key Features

• Fabricated Schedule 40 PVC construction for DWV service
• 8-inch main line with 4-inch branch outlet for size-reducing wye configuration
• Smooth interior bore promotes unrestricted drainage flow
• Solvent-weld socket ends compatible with standard PVC DWV joining methods
• Suitable for above-grade and below-slab sanitary drain installations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for Schedule 40 PVC DWV piping systems with an 8-inch main diameter and 4-inch branch diameter.

Installation Notes

Installation must be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off all flow to the affected drain line and ensure the pipe ends are clean, dry, and deburred before applying primer and solvent cement. Use only PVC-rated primer and cement formulated for DWV applications. Support the fitting per code-required hanger spacing for the pipe diameter and orientation.
