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

1-1/4” PVC 45° DWV Elbow – Hub x Hub Fitting for Drainage Applications

The 1-1/4” PVC 45° DWV Elbow is engineered for use in non-pressurized drainage, waste, and vent (DWV) systems. Its 45-degree sweep provides a smooth directional change, reducing the potential for flow restrictions and promoting efficient waste movement throughout the system. Manufactured to industry dimensional standards, this elbow ensures secure solvent-weld connections with compatible piping.

Constructed from durable polyvinyl chloride, the fitting is resistant to corrosion, scaling, and common chemical exposures encountered in DWV service. It is designed for gravity flow applications and intended for installation in both vertical and horizontal runs where gentle directional transitions are required to maintain system performance.

Product Specifications

• Material: PVC (polyvinyl chloride)
• Nominal Size: 1-1/4 inch
• Connection Type: Hub x Hub (solvent weld)
• Fitting Angle: 45 degrees
• Compliance: ASTM D2665, NSF 14 certified for DWV use

Performance Features

• ✅ Solvent-Weld Socket Ends Provide a leak-resistant mechanical bond when used with standard primer and cement
• ✅ Chemical and Corrosion Resistance Suitable for sanitary waste systems and resistant to household and industrial discharge
• ✅ Low-Profile Sweep Reduces pressure drop compared to sharper angle fittings, maintaining effective drainage velocity
• ✅ Non-Metallic Construction Eliminates risk of galvanic corrosion when installed with dissimilar piping materials
• ✅ Precision Molded Dimensional tolerance supports proper pipe alignment and smooth assembly

Installation Guidelines

Clean and dry all contact surfaces before applying primer and solvent cement. Insert pipe fully into the hub socket and hold until set to ensure alignment. Allow for full cure time per manufacturer instructions before pressure or flow is introduced. This fitting is not suitable for pressurized systems and should only be used in gravity-flow DWV applications.

Common Applications

The 1-1/4” 45-degree PVC elbow is frequently installed in branch lines, fixture arms, and horizontal offsets within DWV systems. It is used in both new construction and retrofits in residential, multi-family, and light commercial buildings, especially in configurations requiring gradual directional changes to meet code or structural constraints.

Did You Know?

45° DWV fittings are preferred over 90° fittings in many lateral drain transitions to reduce the risk of blockages and support system efficiency. Their use also often aligns with plumbing code mandates for minimizing directional flow resistance.

The 1-1/4” PVC 45° DWV Elbow offers a dependable solution for sanitary drainage layouts requiring directional adjustment with minimal flow restriction. Its performance characteristics and compatibility with standard piping materials make it a reliable choice for code-compliant system design.
