Abi Foundry 816 Sanitary Tee 3 in No Hub Cast Iron

Product Description

The ABI FOUNDRY 816 is a 3-inch no-hub cast iron sanitary tee fitting designed for drain, waste, and vent (DWV) piping systems. The tee configuration allows a branch line to connect at a 90-degree angle to a horizontal or vertical run, directing wastewater flow in a sanitary pattern that reduces turbulence and buildup. At 8 inches in length, it is sized for standard residential and light commercial rough-in work. Licensed plumbers install this fitting as part of code-compliant DWV assemblies where cast iron is specified for durability, noise reduction, or local code requirements.

This fitting is used in new construction and remodel plumbing projects where 3-inch no-hub cast iron DWV piping is called out. Typical applications include toilet drain branch connections, lavatory stack tie-ins, and horizontal-to-vertical transitions in soil and waste stacks. The no-hub end style accepts standard no-hub couplings, making it compatible with no-hub cast iron pipe sections used in residential, multi-family, and light commercial plumbing systems. No soldering, threading, or hub lead-and-oakum work is required.

Key Features

• 3-inch nominal size fits standard no-hub cast iron DWV pipe runs
• No-hub end style connects using standard no-hub stainless band couplings
• Cast iron construction provides durability and sound attenuation versus plastic alternatives
• Sanitary tee flow pattern supports proper wastewater drainage direction
• 8-inch overall length accommodates typical branch fitting clearances in wall and floor assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch no-hub cast iron DWV piping systems using standard no-hub coupling connections.

Installation Notes

Installation is performed by a licensed plumber in accordance with the applicable plumbing code, including IPC or local adopted equivalents. Shut off the water supply and verify the line is depressurized and drained before cutting into an existing stack or branch. Secure no-hub couplings to the manufacturer torque specification using a torque-limiting driver. Support horizontal runs per code-required hanger spacing for cast iron pipe to prevent joint stress.
