Copperfit 1A1648 Abs Dwv Long Sweep 90 Elbow 4 in

Product Description

The COPPERFIT 1A1648 is a 4-inch ABS DWV long sweep 90-degree elbow designed for drain, waste, and vent piping systems. The long-sweep geometry produces a gradual directional change, reducing flow restriction and minimizing the risk of solids buildup compared to short-pattern fittings. Constructed from acrylonitrile butadiene styrene (ABS), this fitting offers solid resistance to common drain chemicals and is suited for below-grade and above-grade interior applications. Licensed plumbers install this fitting during rough-in on residential and light commercial DWV systems.

This elbow is used wherever a 4-inch DWV line requires a 90-degree direction change with a smooth, long-radius transition. Typical applications include main drain runs, toilet drain connections, and horizontal-to-vertical offsets in residential and commercial plumbing systems. The 4-inch diameter accommodates standard soil and waste lines. It is commonly specified where code requires long-sweep fittings on horizontal drain runs.

Key Features

• Long-sweep radius reduces flow restriction and helps prevent blockages in drain lines
• 4-inch diameter fits standard DWV soil and waste piping
• ABS construction resists common household and commercial drain chemicals
• 90-degree sweep handles horizontal-to-horizontal and horizontal-to-vertical transitions
• Solvent-weld socket ends for secure, leak-resistant joints

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch ABS DWV piping systems in residential and light commercial plumbing applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or locally adopted plumbing code. Shut off the water supply and confirm the drain line is clear and dry before solvent-welding. Use ABS-compatible primer and cement per manufacturer instructions and allow full cure time before restoring flow. Support horizontal runs per code-required hanger spacing for 4-inch ABS pipe.
