Abi Foundry 1320 Cast Iron No Hub Wye 4 X 2 Inch

Product Description

The ABI FOUNDRY 1320 is a cast iron no-hub wye fitting designed for use in drain, waste, and vent (DWV) piping systems. This fitting connects a 2-inch branch line to a 4-inch main line at a wye angle, allowing for smooth, low-turbulence flow transitions. At 6-5/8 inches in length, it is sized for standard residential and light commercial DWV applications. The no-hub end style accepts standard no-hub couplings and bands, making it compatible with modern cast iron pipe assembly methods. Licensed plumbers and pipefitters typically install this fitting in underground or above-ground drain systems where cast iron is specified for noise reduction or code compliance.

This wye fitting is used in residential and commercial DWV piping systems where a 2-inch branch must tie into a 4-inch horizontal or vertical drain stack. Typical installation scenarios include bathroom group connections, floor drain tie-ins, and branch drain roughing. The no-hub configuration allows for straightforward field assembly without the need for lead and oakum joints. Cast iron construction provides the mass and rigidity required in applications where noise attenuation or long-term durability in concrete slab or below-grade installations is a priority.

Key Features

• 4 x 2 inch nominal sizing for branch-to-main-stack connections
• No-hub end style for use with standard no-hub couplings and torque bands
• Cast iron construction for durability, noise reduction, and longevity
• 6-5/8 inch overall length suits standard rough-in spacing
• Suitable for above-grade and below-grade DWV installations

Compatibility

Designed as an OEM-style no-hub cast iron wye fitting for use in residential and commercial DWV piping systems with 4-inch main lines and 2-inch branch lines using standard no-hub couplings.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) or applicable local plumbing codes. Shut off water supply and ensure the drain system is depressurized before cutting into existing piping. No-hub couplings must be torqued to manufacturer specifications using a calibrated torque driver. Do not use this fitting with hub-and-spigot or threaded pipe ends without appropriate adapter fittings.
