Abi Foundry 1318 Cast Iron No Hub Wye 3 Inch

Product Description

The ABI FOUNDRY 1318 is a 3-inch cast iron no-hub wye fitting designed for drain, waste, and vent (DWV) piping systems. It provides a 45-degree branch connection that allows a secondary line to merge with the main run at a flow-friendly angle, reducing turbulence and helping maintain proper drainage velocity. At 8 inches in length, this fitting suits standard residential and commercial DWV rough-in work. The no-hub end style accepts standard no-hub couplings and clamps, making it compatible with typical cast iron no-hub installation methods. Licensed plumbers and pipefitters are the primary installers of this fitting.

This wye fitting is used in underground, in-wall, and above-slab cast iron DWV assemblies where a branch takeoff is required. It is appropriate for both residential and light commercial applications, including sanitary drain lines, soil stacks, and vent configurations. The 3-inch nominal size is a common branch dimension in residential bathroom and kitchen rough-in layouts. Installers often pair this fitting with no-hub couplings and a torque wrench to achieve proper band clamp engagement per CISPI and ASTM standards.

Key Features

• 3-inch nominal no-hub end style for use with standard no-hub couplings and clamps
• Cast iron construction provides durability and sound-dampening characteristics in DWV systems
• 8-inch overall length accommodates standard rough-in spacing
• Wye configuration supports flow-friendly branch connections in sanitary drain and vent lines
• Suitable for both residential and light commercial DWV applications

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 3-inch no-hub cast iron DWV piping systems following CISPI 301 and ASTM A888 no-hub cast iron soil pipe standards.

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 line is depressurized and drained before cutting into an existing system. Use appropriate no-hub couplings and a calibrated torque wrench to tighten band clamps to the coupling manufacturer's specified torque. Support the fitting per code-required hanger spacing for cast iron pipe to prevent joint stress and misalignment.
