2-Inch PVC Street 45-Degree Elbow – DWV Fitting for Directional Flow Transitions

The 2-inch PVC Street 45° Elbow is a drainage fitting used in DWV systems to create directional changes while maintaining flow integrity. Its street-end configuration (spigot x hub) allows for direct insertion into another fitting without the need for a short connecting pipe, making it ideal for space-constrained installations.

This elbow is constructed from schedule-rated polyvinyl chloride (PVC), meeting industry standards for use in non-pressurized waste and vent systems. It is suitable for both new construction and retrofit applications across residential, commercial, and light industrial buildings where chemical resistance and dimensional accuracy are required.

Performance and Material Attributes

• ✅ 45-Degree Sweep Angle – Provides smoother directional transitions to reduce flow turbulence and maintain consistent drainage velocity.
• ✅ Street End Design – Spigot end connects directly to socketed fittings, minimizing required pipe segments and reducing joint count.
• ✅ Nonmetallic Durability – PVC construction resists corrosion, scale buildup, and biological growth in gravity-driven waste systems.
• ✅ Thermal Stability – Rated for use within DWV temperature limits, including residential hot water drainage conditions.
• ✅ Code-Conforming Geometry – Manufactured in compliance with ASTM D2665 and ASTM D1784 standards for PVC fittings.

Specifications

• Material: PVC (Type 1, Grade 1 per ASTM D1784)
• Nominal Size: 2 inches
• Connection Type: Spigot x Hub (street 45° elbow)
• Application: Gravity-fed drain, waste, and vent systems
• Standard Compliance: ASTM D2665 / D1784

Use Case and Installation Context

Typically installed in horizontal drainage lines to redirect flow while maintaining proper slope and system velocity. The 45-degree elbow is preferred over 90-degree fittings in branch lines and fixture arms where reduced directional resistance is required. Ideal for vertical-to-horizontal transitions and offset configurations in confined chases or wall cavities.

Installation Considerations

Fittings must be solvent-welded using PVC-compatible primer and cement per manufacturer and code requirements. Ensure all joints are properly cleaned and seated to full insertion depth before curing. All installations should comply with applicable plumbing codes such as IPC or UPC, including required cleanouts and support intervals.

Note on Code Compliance

Lead-free, nonmetallic fittings such as this one are compliant with current code requirements for DWV systems and are suitable for use in potable and non-potable plumbing assemblies as specified.
