Abi Foundry 1552 Double Wye 6x4 in No Hub Cast Iron

Product Description

The ABI FOUNDRY 1552 is a double wye fitting designed for no-hub cast iron drain, waste, and vent (DWV) piping systems. Cast from gray iron, this fitting accepts a 6-inch main line with dual 4-inch branch outlets arranged in a symmetrical wye configuration. At 11-3/16 inches in length, it provides a compact and rigid junction point for combining or splitting flow in below-grade or above-grade drainage runs. Licensed plumbers and pipefitters install this type of fitting when a single stack or horizontal run must receive simultaneous branch connections on opposing sides.

This fitting is suited for residential and light commercial DWV installations where cast iron is specified for noise reduction, durability, or code compliance. Common applications include sanitary drain stacks, building drain headers, and horizontal collector lines in multi-unit residential, hospitality, or healthcare construction. The no-hub end style connects using standard no-hub couplings and clamps, making it compatible with no-hub cast iron piping systems assembled to CISPI or ASTM standards.

Key Features

• Double wye configuration provides two 4-inch branch takeoffs from a single 6-inch run
• No-hub end style allows connection with standard no-hub couplings without lead or oakum
• Cast iron construction provides long service life and effective sound attenuation in drain lines
• 11-3/16 inch body length suits tight vertical or horizontal installation spaces
• Suitable for sanitary DWV service in residential and commercial plumbing systems

Compatibility

Designed as an OEM-style no-hub cast iron DWV fitting for use with standard 6-inch and 4-inch no-hub cast iron pipe and compatible no-hub couplings meeting CISPI 310 or ASTM C1277 requirements.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off all flow and relieve any system pressure before removing an existing fitting or cutting into an active drain line. No-hub couplings must be torqued to the coupling manufacturer's specification using a calibrated torque wrench. Support the fitting and adjacent piping per code-required hanger spacing to prevent stress on the no-hub joints.
