4 inch ABS DWV 90 Degree Elbow Plastic x Plastic

4” ABS DWV 90° Elbow – High-Performance Fitting for Drainage Systems

The 4 inch ABS DWV 90° Elbow is engineered for non-pressurized sanitary drainage and vent applications, providing an efficient way to redirect flow at a right angle within residential and commercial DWV systems. Molded from durable black ABS thermoplastic, this elbow delivers long-lasting performance and reliable system integration.

Designed for use in gravity-fed drainage systems, this fitting meets ASTM D2661 and CSA B181.1 standards. Its solvent-weld hub connections ensure a secure, leak-resistant seal when properly bonded to ABS piping. This elbow is an essential component for routing DWV lines around obstacles, through walls, or within confined spaces.

Product Features

• ✅ 90° Sweep Radius – Supports smooth directional changes in horizontal and vertical DWV piping with minimal flow restriction.
• ✅ Solvent Weld Hub Ends – Designed for permanent, pressure-tight joints when used with approved ABS solvent cement.
• ✅ Rugged ABS Material – Offers excellent resistance to chemical corrosion, impact, and temperature variations typical of DWV environments.
• ✅ Lightweight Construction – Reduces handling time and effort during installation, while maintaining dimensional stability.
• ✅ Code Compliant – Certified to industry performance standards for use in residential and commercial DWV systems.

Specifications

Installation Guidance

Installation requires proper preparation of pipe ends and application of approved ABS solvent cement. Ensure clean, square cuts and full insertion into the hub until the pipe bottoms out. Hold fittings in place briefly to allow set time and verify full cure per manufacturer's cement instructions. Do not use for pressurized or hot water systems.

Applications

Commonly used in horizontal-to-vertical transitions in drainage systems, this elbow facilitates waste flow from fixtures, cleanouts, or vent stacks. It is suitable for use behind walls, below floors, and within basement drain lines. Ensure proper slope and directional alignment for code-compliant flow performance.

Did You Know?

ABS DWV fittings retain structural integrity in below-freezing temperatures and are frequently used in colder climate installations. Their black color allows easy identification on job sites and during inspections.

When specifying components for a DWV system, the 4” ABS 90° elbow provides a proven solution for efficient direction changes while maintaining code compliance and long-term reliability in the field.
