2 inch PVC DWV Vent 90 Degree Elbow Plastic x Plastic

2 inch PVC 90° Vent Elbow – DWV Fitting, Hub x Hub

The 2 inch PVC 90-degree vent elbow is a Schedule 40 drainage fitting used in non-pressurized DWV (Drain, Waste, and Vent) systems to redirect flow and maintain proper venting. This elbow facilitates a right-angle change in piping direction, typically in vertical-to-horizontal or horizontal-to-vertical configurations where vent lines intersect the main stack or wall cavity.

Manufactured from rigid polyvinyl chloride (PVC), this fitting meets ASTM D2665 specifications and is certified for use in systems governed by IPC and UPC codes. Its hub x hub design is solvent-welded to pipe for a permanent, watertight connection and is compatible with 2 inch nominal Schedule 40 DWV piping.

Performance Characteristics

• ✅ Nominal Size: 2-inch (both ends, socket connection)
• ✅ Configuration: 90° elbow for DWV venting systems
• ✅ Material: PVC Type I, Grade I per ASTM D1784
• ✅ Joining Method: Solvent weld (hub x hub)
• ✅ Compliance: Meets ASTM D2665, NSF 14, and CSA B181.2 standards

Installation Considerations

Install using PVC primer and solvent cement specifically formulated for DWV systems. Ensure pipe ends are clean, dry, and square-cut. Do not use this fitting in pressurized systems or for force-main applications. Proper support spacing and pipe alignment are essential to prevent joint stress and misalignment.

Common Applications

Used in residential and light commercial vent stacks and horizontal waste branches, this elbow is commonly installed behind walls, in crawl spaces, or under floors to facilitate drainage venting while conserving space. It is not intended for use in high-flow or high-pressure scenarios such as sanitary sweep elbows.

Material Notes

Schedule 40 PVC provides excellent chemical resistance, dimensional stability, and ease of handling. The smooth interior surface reduces friction loss and resists scale buildup over time. While PVC is thermoplastic, this fitting is rated for use within the temperature ranges typical of DWV service conditions (max 140°F intermittent).
