Copperfit 1A1786 Abs Dwv Long Turn Combo Tee 4 in

Product Description

The COPPERFIT 1A1786 is a 4-inch ABS DWV long turn combination tee, commonly called a combo tee, designed for use in drain, waste, and vent piping systems. This fitting allows a branch connection while maintaining a sweeping, long-turn radius that promotes smooth wastewater flow and reduces the risk of blockage at the junction. The ABS construction provides lightweight handling and resistance to typical household drain chemicals. Licensed plumbers and pipefitters install this type of fitting during rough-in work in both new construction and remodel projects.

This combination tee is suited for residential and light commercial DWV applications where a directional branch outlet is needed along a horizontal or vertical drain run. The long-turn geometry makes it appropriate for installations where flow dynamics matter, such as main drain stacks or primary horizontal runs that serve multiple fixtures. It is used in above-slab and below-slab drain configurations depending on local code requirements.

Key Features

• Long-turn sweep radius promotes unobstructed wastewater flow through the branch connection
• 4-inch ABS construction for lightweight handling and chemical resistance
• Combination tee design allows simultaneous straight-through and branch flow paths
• Suitable for both horizontal and vertical DWV piping runs
• Consistent wall thickness for reliable solvent-weld joints

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code or applicable local plumbing code. Shut off water supply and ensure the existing drain line is clear before cutting into an active system. Use approved ABS solvent cement and primer as required by local code, and allow full cure time before restoring flow. Follow local code for required cleanout access and venting requirements at branch connections.
