1-1/4 inch PVC DWV 45 Degree Street Elbow Fitting x Plastic

1-1/4 Inch PVC DWV 45° Street Elbow – Street x Hub Connection

The 1-1/4 inch PVC DWV 45 Degree Street Elbow is engineered for directional changes in non-pressurized drain, waste, and vent systems. Featuring a street (spigot) x hub configuration, it provides a compact and efficient solution for connecting piping at a 45° offset, reducing the need for additional couplings in tight or angled installations.

Application and Performance

Manufactured from durable polyvinyl chloride (PVC), this fitting is suitable for use in DWV systems where corrosion resistance, lightweight handling, and ease of solvent welding are essential. The 45° sweep is optimized to promote smooth flow transition and reduce the potential for clogs or turbulence in horizontal and vertical runs.

Key Attributes

• Material: Schedule 40 PVC
• Connection Type: Spigot (Street) x Hub
• Angle: 45 degrees for gradual direction change
• Nominal Size: 1-1/4 inch
• Standards Compliance: Meets ASTM D2665 and CSA B181.2 for DWV applications

Installation Considerations

Designed for solvent-weld connections, this elbow should be used with approved PVC primer and cement. Ensure both surfaces are clean and properly prepared for a secure bond. Proper alignment and insertion depth must be verified during installation to maintain system integrity and prevent leaks.

Typical Use Cases

Commonly used in residential and light commercial DWV piping layouts, especially where directional changes are needed in confined spaces such as wall cavities or between joists. Its street x hub design allows for connection directly into another fitting without the need for an additional pipe stub.

Advantages in System Design

• Reduces the need for extra couplings in offset configurations
• Improves flow characteristics compared to sharp 90° transitions
• Non-metallic composition resists corrosion and chemical degradation

This 1-1/4 inch PVC DWV 45° Street Elbow is a reliable component for optimizing layout efficiency and hydraulic performance in code-compliant drainage systems.
