Abi Foundry 688 1/16 Bend 8 in No-hub Cast Iron Dwv

Product Description

The ABI FOUNDRY 688 is a 1/16 bend DWV fitting designed for no-hub cast iron drain, waste, and vent piping systems. This fitting provides a 22.5-degree change of direction in horizontal or vertical drain runs and is manufactured from cast iron for long-term durability in demanding commercial and residential applications. The no-hub end style accepts standard no-hub couplings, making field assembly straightforward without the need for lead and oakum joints. Licensed plumbers and pipefitters install this fitting as part of gravity-flow DWV systems in new construction and retrofit work.

This fitting is sized at 8 inches nominal and is suited for large-diameter DWV trunk lines found in commercial buildings, multistory residential construction, and industrial facilities. It is used wherever a shallow directional change is required in a cast iron drain system, including horizontal offsets and stack connections. The no-hub configuration makes it compatible with standard no-hub band couplings used throughout the trade.

Key Features

• 1/16 bend geometry provides a 22.5-degree directional change in DWV piping runs
• Cast iron construction offers excellent durability and sound dampening in drain systems
• No-hub end style accepts standard no-hub couplings for tool-free lead-free assembly
• 8-inch nominal size suits large-diameter commercial and industrial drain applications
• Manufactured to DWV service requirements for drain, waste, and vent systems

Compatibility

Designed as an OEM-style no-hub cast iron DWV fitting compatible with standard 8-inch no-hub band coupling systems used in commercial and residential drain, waste, and vent piping.

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 verify the drain system is depressurized before beginning work. Use properly torqued no-hub shielded couplings rated for the pipe diameter and service type. Support all cast iron piping per code-required hanger spacing to prevent joint stress and sagging.
