Copperfit 1A1783 Abs Dwv Long Turn Combo Tee 1.5 in

Product Description

The COPPERFIT 1A1783 is a 1.5-inch ABS DWV long turn combination tee, commonly called a combo tee, designed for drain, waste, and vent piping systems. This fitting allows a branch connection while maintaining smooth, long-radius flow through the run, reducing turbulence and the risk of solids buildup. Made from acrylonitrile butadiene styrene (ABS) plastic, it is lightweight, corrosion-resistant, and solvent-weld compatible. Licensed plumbers and pipe fitters install this fitting in residential and light commercial DWV rough-in work.

The 1A1783 combo tee is suited for horizontal drain runs where a branch inlet is needed at a swept angle rather than a sharp 90-degree tee. The long-turn design meets code requirements in jurisdictions that prohibit short-pattern tees on horizontal-to-horizontal connections. It fits into standard 1.5-inch ABS DWV piping layouts used in bathroom, laundry, and kitchen drain rough-ins.

Key Features

• Long-turn sweep design reduces flow restriction and minimizes clog risk on horizontal drain lines
• ABS construction offers corrosion resistance and compatibility with standard ABS solvent cement
• 1.5-inch nominal size fits common lavatory, laundry, and kitchen branch drain applications
• Combination tee geometry allows simultaneous run-through and branch connections in a single fitting
• Lightweight material simplifies handling during overhead and under-floor rough-in installations

Compatibility

Designed as an OEM-style replacement and new-construction fitting for standard 1.5-inch ABS DWV drain, waste, and vent piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or locally adopted plumbing codes. Shut off water supply and ensure the drain system is cleared before cutting into existing lines. Clean and dry all pipe ends, apply ABS solvent cement per manufacturer instructions, and allow full cure time before pressure-testing the system. Do not use ABS fittings with PVC pipe without an approved transition coupling and the correct transition cement.
