Copperfit 1A1645 Abs Dwv Long Sweep 90 Elbow 1.5 in

Product Description

The COPPERFIT 1A1645 is a 1.5-inch ABS DWV long sweep 90-degree elbow designed for drain, waste, and vent piping systems. The long sweep geometry provides a gradual directional change compared to a standard 90, which reduces flow restriction and helps maintain drainage velocity. This fitting is manufactured from ABS (acrylonitrile butadiene styrene) thermoplastic, making it lightweight and resistant to common drain line chemicals. Plumbers and pipefitters install this type of fitting in residential and light commercial DWV rough-in applications where code or system design calls for a long-turn 90 rather than a short-pattern elbow.

This elbow is suited for horizontal-to-horizontal and horizontal-to-vertical drain transitions in standard gravity-flow DWV systems. Typical applications include branch drain lines, fixture connections, and stack offsets where maintaining flow efficiency is a priority. At 1.5 inches, this fitting is commonly used on lavatory drains, bathtub drains, and similar fixture branch lines.

Key Features

• Long sweep 90-degree geometry reduces flow restriction in drain lines
• 1.5-inch nominal size suits standard lavatory and tub drain branch lines
• ABS construction is lightweight and resistant to common household drain chemicals
• Solvent-weld socket ends for secure, code-compliant connections
• Weighs 0.21 pounds for easy single-hand handling during rough-in

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1.5-inch ABS DWV piping systems following standard socket-weld dimensions.

Installation Notes

Installation is performed by licensed plumbers in jurisdictions governed by the IPC or applicable local plumbing code. Solvent-cement all joints using ABS-rated cement and primer per manufacturer and code requirements. Ensure proper slope on horizontal runs, typically 0.25 inches per foot as required by code, and verify all DWV rough-in is inspected before concealment. Do not use PVC solvent cement on ABS fittings.
