Old Castle v-904 45 Degree Wye 4 Inch SDR35 Pvc Fitting

Product Description

The OLD CASTLE v-904 is a 45-degree wye fitting designed for gravity-flow sanitary drain, waste, and vent (DWV) piping systems. Molded from PVC to SDR 35 specifications, this fitting accepts 4-inch pipe at all three ports via hub connections, making it a standard choice for joining branch lines to main drain runs. The 45-degree angle reduces turbulence and helps maintain flow velocity compared to a standard 90-degree tee. Licensed plumbers and drainage contractors install this fitting in below-grade and above-grade DWV applications where SDR 35 PVC is the specified pipe material.

This fitting is used in residential and light commercial sanitary sewer and storm drain systems where PVC SDR 35 pipe is required. Its hub-by-hub-by-hub configuration suits direct solvent-cement connections to same-size pipe at the main run and branch outlet. The 45-degree wye orientation supports proper drainage slope and is commonly used when transitioning from a vertical stack or introducing a lateral branch into a horizontal run. The fitting measures 9.71 inches in length, 4.5 inches in width, and 8.8 inches in height.

Key Features

• 45-degree wye geometry promotes smooth directional flow transitions in DWV systems
• Molded PVC construction rated to SDR 35 for gravity-drain applications
• All three ports are 4-inch hub connections for solvent-cement joining
• Consistent molded dimensions support accurate rough-in layout
• Suitable for below-grade sanitary and storm drainage installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch SDR 35 PVC DWV piping systems using hub-end solvent-cement connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off flow and verify the line is clear before cutting into an existing drain system. Use only PVC solvent cement rated for SDR 35 DWV fittings and follow manufacturer cure times before restoring flow. Do not use this fitting on pressure-rated water supply lines.
