8 inch PVC DWV 45 Degree Elbow Plastic x Plastic

8 inch PVC DWV 45-Degree Elbow (Hub x Hub) – Built for Smooth Directional Flow

The 8 inch PVC DWV 45° Elbow (Hub x Hub) is engineered for use in gravity-fed drain, waste, and vent (DWV) systems. This fitting allows for gradual directional changes, helping maintain consistent flow and minimizing turbulence within horizontal or vertical piping configurations. Its 45-degree sweep is ideal for large-scale residential, commercial, and industrial plumbing applications where smooth redirection is essential.

Product Features

• Connection Type: Hub x Hub (Slip fit connections for solvent weld joining)
• Angle: 45 degrees – promotes improved flow over sharp 90° transitions
• Material: White PVC – corrosion-resistant and suitable for non-pressurized DWV systems
• Nominal Size: 8 inches
• Surface Finish: Smooth interior reduces friction and helps prevent build-up

Installation Requirements

Installation of this elbow requires solvent cement welding. Ensure pipe ends are clean and square, and apply approved primer and cement per code requirements. Proper insertion depth and alignment are critical to creating a leak-free seal. Due to the size of this fitting, handling and joining may require multiple personnel or bracing during assembly.

Applications

The 8 inch 45° PVC elbow is used in DWV systems where directional change is required without compromising flow velocity. Common applications include:

• Main sanitary drainage lines in large buildings
• Stormwater and vent line transitions
• Subgrade piping in commercial or institutional systems

Standards and Compliance

• Conforms to ASTM D2665 for PVC DWV fittings
• Designed for non-pressurized systems only
• Listed for use in accordance with NSF/ANSI Standard 14

Technical Considerations

This fitting should be installed with proper slope in horizontal applications to maintain flow direction and drainage integrity. Where necessary, support piping to avoid stress at joints. Do not use this product for compressed air or pressurized fluid systems.

Did You Know?

Using a 45-degree elbow instead of a 90-degree fitting in DWV applications helps maintain better laminar flow and reduces the chance of blockages, especially in large-diameter pipe runs.

The 8 inch PVC DWV 45° Elbow is a critical fitting for smooth transitions in large drainage systems. With its proven design, durable construction, and code-compliant performance, it’s a preferred choice for professionals working on complex plumbing layouts.
