4 inch ABS DWV 45 Degree Elbow Plastic x Plastic

4 inch ABS DWV 45° Elbow – Schedule 40 Fitting for Non-Pressurized Drainage Applications

The 4 inch ABS (Acrylonitrile Butadiene Styrene) DWV 45° Elbow is designed for use in gravity-fed drainage, waste, and vent systems. This elbow fitting facilitates directional changes in horizontal or vertical DWV lines and is molded to meet dimensional and performance standards for ABS Schedule 40 plumbing systems.

Manufactured with high-performance thermoplastic, the fitting maintains consistent wall thickness and smooth interior surfaces to promote unimpeded flow and reduce the risk of clogging. The 45° angle provides a gentler sweep than 90° fittings, improving flow velocity and reducing turbulence in system transitions.

Specifications

• Size: 4 inch nominal pipe size (NPS)
• Material: ABS Schedule 40
• Angle: 45 degrees
• End Connection: Hub x Hub (solvent weld)
• Standards: ASTM D2661 / D3311 compliant
• Listings: NSF DWV certified

Product Features

• Chemical and Impact Resistant: ABS is resistant to a broad range of household and industrial chemicals and offers excellent impact strength for above- and below-ground use.
• Solvent Weld Joint: Hub connections are designed for solvent welding to ensure a leak-resistant, permanent bond.
• Consistent Wall Thickness: Ensures structural integrity under static loads typically found in non-pressurized systems.
• Lightweight Material: Reduces handling fatigue and speeds up installation, especially in multi-fitting assemblies.

Installation Considerations

Use only ABS-compatible solvent cement for bonding. Clean and dry all mating surfaces prior to assembly. Verify that piping is fully inserted into the hub to maintain system alignment and prevent joint stress. Allow adequate cure time in accordance with cement manufacturer specifications. This fitting is not intended for use in pressurized systems or hot water lines.

Typical Applications

• Residential and commercial DWV systems
• Underground drainage installations
• Vent stacks and waste line offsets
• Fixture branch connections where directional changes are required

Note:

When specifying fittings for code-compliant installations, always refer to local plumbing codes. This fitting complies with national standards for ABS DWV applications and is suitable for new construction or retrofits involving ABS drainage systems.
