Material: cast iron, “Special Toronto” series, high resistance to mechanical stress and impact.
Configuration: Special long double TY, side inlets with mechanical seals (MJ).
Dimensions: 3" x 3" x 1-1/2"; available with two or four inputs.
Profile: long design, smooth transition for optimal flow of wastewater and air.
Applications: drainage, exhaust, and ventilation (DEV); residential, commercial, and institutional. Ideal for connecting multiple units to the same point in the system, particularly in attached bathrooms in multi-family dwellings.
Why cast iron? Since it is non-combustible, it is ideal for fire-resistant assemblies. Its acoustic properties reduce flow noise, a real advantage in apartments, hotels, and hospitals. And its durability—even when installed underground or exposed to temperature fluctuations—means less maintenance over the long term.
Cast-iron piping systems are less likely to fail due to design errors or soil compaction, ensuring a robust, long-lasting installation.

The CM-CANADA™ Special Long Double TY Cast Iron fitting from the “Special Toronto” line connects multiple branch lines to the main drainage, discharge, and ventilation system from a single connection point. Available in 3" x 3" x 1-1/2" with two or four side inlets featuring mechanical joints (MJ), it consolidates connections—such as those for back-to-back-installed fixtures—while maintaining the smooth transition of the long model that promotes flow.
Sturdy, non-combustible, and naturally quiet, this cast-iron fitting is designed for residential, commercial, and institutional installations where fire safety and durability are essential.
