Flat Oval Horizontal T-Piece

The Flat Oval Horizontal T-Piece is designed to create a reliable side branch from a main flat oval duct run, allowing airflow to split evenly across horizontal ducting systems. Its low-profile flat oval shape makes it ideal for installations where ceiling voids are limited, while still maintaining the high air volume typically associated with round ductwork. Built for strength and accuracy, this fitting ensures efficient airflow distribution and integrates seamlessly into flat oval HVAC duct systems used in commercial, retail and industrial environments. Fits into shallow ceiling voids where round ducting is too tall, maintaining the high-volume capacity required for efficient HVAC performance Fabricated from premium hot-dip galvanised steel for great structural rigidity and long-term corrosion resistance The seam provides a robust permanent seal Ideal for exposed-ceiling designs in commercial and high-end retail spaces Fittings supplied small end as standard to fit into straight duct Apart from stiffening requirements, flat oval ducts follow the same construction standards across all pressure ranges defined in DW144 In some cases, additional stiffening is required in the form of tie bars which are fitted in line with DW144
