1-1/4 inch PVC 45° Elbow – Solvent Weld Fitting for DWV Systems

The 1-1/4 inch PVC 45-degree elbow is a socket-type fitting used to redirect flow in drain, waste, and vent (DWV) systems. Engineered for use in non-pressurized sanitary piping applications, this fitting allows a 45° change in direction while maintaining efficient flow characteristics and minimizing turbulence within the system.

Molded from durable Schedule 40 PVC in compliance with ASTM D2665 and CSA B181.2 standards, this elbow is designed for solvent cement installation and is suitable for use in residential and commercial DWV configurations.

Product Features

• ✅ Material: Polyvinyl Chloride (PVC) conforming to ASTM D1784, Cell Class 12454
• ✅ Size: 1-1/4 inch nominal pipe size
• ✅ Connection Type: Slip x Slip (solvent weld sockets on both ends)
• ✅ Angle: 45 degrees for directional changes with reduced flow resistance
• ✅ Temperature Range: Rated for use up to 140°F in gravity drainage applications

Installation Requirements

This elbow must be solvent welded to compatible PVC pipe using approved primer and cement. Pipe ends should be clean, square-cut, and free of burrs. Dry fit the components to verify alignment before final bonding. Follow ASTM D2855 procedures and allow appropriate cure time prior to system testing or backfill if installed below grade.

Common Applications

Used in DWV piping layouts for residential, multi-family, and light commercial construction. This fitting is ideal for transitions in lateral drains, vertical stacks, and branch lines where smooth directional shifts are required. It is often specified where sharp 90° angles are discouraged to maintain proper drain line velocity.

Compliance and Ratings

The 1-1/4 inch PVC 45° elbow meets UPC and IPC code requirements and is third-party listed for use in non-pressurized plumbing systems. It is suitable for aboveground or underground DWV installations and is resistant to corrosion from wastewater and most non-pressurized chemical residues.
