Abi Foundry 572 Cast Iron No Hub 1/6 Bend 3 Inch

Product Description

The ABI FOUNDRY 572 is a cast iron 1/6 bend fitting designed for drain, waste, and vent (DWV) piping systems. The no-hub end style accepts standard no-hub couplings for tool-free alignment and a secure, leak-resistant connection. At a 3-inch nominal size, this fitting redirects flow at approximately 60 degrees, making it a practical choice where a gradual directional change is required in a drainage run. Cast iron construction provides the mass and rigidity that plumbers rely on for noise dampening and long-term durability in both residential and commercial installations.

This fitting is intended for use in below-grade, above-grade, and in-wall DWV piping applications. It is commonly installed in drain and waste lines where a less aggressive change of direction than a quarter bend is needed, such as in building drain mains, branch connections, and stack offsets. The no-hub interface allows connection to standard no-hub cast iron pipe and fittings using approved no-hub couplings and stainless steel bands, which is the standard method for this type of system in commercial and multi-family construction.

Key Features

• Cast iron construction for superior noise attenuation and long service life in DWV systems
• 1/6 bend geometry provides approximately 60-degree directional change for gradual flow redirection
• No-hub end style compatible with standard no-hub coupling connections
• 3-inch nominal size fits standard 3-inch cast iron DWV pipe
• Suitable for residential and commercial drain, waste, and vent applications

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 couplings.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is clear before cutting into an existing system. Use an approved no-hub torque wrench to tighten no-hub coupling bands to the coupling manufacturer's specified torque. Do not use open-flame tools near cast iron no-hub couplings with neoprene gaskets.
