3 inch PVC DWV Vent 90 Degree Elbow Plastic x Plastic

3 inch PVC Vent 90° Elbow – Hub x Hub DWV Fitting

The 3 inch PVC 90-degree vent elbow is engineered for use in drain, waste, and vent (DWV) systems requiring directional changes in horizontal or vertical pipe runs. This fitting facilitates efficient air circulation and wastewater flow in non-pressurized applications. Its hub x hub configuration allows for solvent-weld connections, ensuring a secure and permanent joint when installed to code.

Molded from Schedule 40 PVC compound in accordance with ASTM D2665, the elbow offers chemical resistance and structural performance suitable for residential, commercial, and institutional projects where DWV standards apply. The smooth internal bore promotes unobstructed flow and minimizes buildup in system transitions.

Key Performance Characteristics

• ✅ 90° Directional Change – Designed for routing piping at a right angle to meet layout and code requirements in DWV configurations.
• ✅ Hub x Hub Ends – Socket-style connection points accept standard 3 inch nominal PVC pipe for solvent-weld joints.
• ✅ Schedule 40 Wall Thickness – Compatible with standard DWV piping systems, offering structural consistency and dimensional accuracy.
• ✅ Material Integrity – Manufactured from rigid polyvinyl chloride (PVC), resistant to corrosion, scaling, and microbial attack.
• ✅ Code Compliance – Meets applicable ASTM standards (D2665) and is certified by third-party listing agencies for plumbing code applications.

Installation Parameters

For proper installation, pipe ends and socket interiors should be clean and dry. Use primer and solvent cement specifically formulated for PVC piping. Insert the pipe fully into the hub until seated, and allow curing per manufacturer instructions. This fitting is not intended for pressurized fluid systems and should be used exclusively in gravity flow DWV applications.
