Abi Foundry 812 Sanitary Tee 3x1-1/2 in No Hub Cast Iron

Product Description

The ABI FOUNDRY 812 is a no-hub cast iron sanitary tee fitting designed for use in drain, waste, and vent (DWV) piping systems. It features a 3-inch main run with a 1-1/2-inch side outlet and measures 6.5 inches in length. The no-hub end style accepts standard no-hub couplings, eliminating the need for hub-and-spigot assembly. Cast iron construction provides the durability and noise-dampening characteristics required in commercial and residential drain systems. Licensed plumbers and pipefitters install this fitting as part of rough-in drain and vent assemblies.

This sanitary tee is suited for residential and light commercial DWV applications where a branch connection is needed off a 3-inch vertical or horizontal drain stack. The 1-1/2-inch branch outlet accommodates typical fixture drain lines such as those from lavatories, utility sinks, or similar fixtures. The no-hub configuration simplifies installation in retrofit and new-construction scenarios where hub fittings are not specified.

Key Features

• No-hub end style accepts standard no-hub couplings for fast, tool-assisted connection
• 3-inch main run with 1-1/2-inch branch outlet for mixed-size drain connections
• Cast iron construction for long service life and low noise transmission in drain lines
• 6.5-inch body length fits standard rough-in spacing in DWV assemblies
• Sanitary tee geometry directs flow toward the main stack to reduce turbulence

Compatibility

Designed as an OEM-style replacement or new-installation fitting for no-hub cast iron DWV piping systems using standard 3-inch and 1-1/2-inch no-hub couplings per CISPI and ASTM specifications.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and ensure the drain system is empty before cutting into an existing line. No-hub couplings require a torque wrench set to the coupling manufacturer's specified setting — do not over-tighten the stainless steel clamps. Verify proper slope and support spacing for horizontal runs per code before final inspection.
