Tees and Reducing Tees

Rectangular Duct and Fittings

Tees and Reducing Tees

  • A reducing tee is used when the inlet and outlet diameters are different. This type of tee allows the connection of ducts with different sizes.

  • In addition to reducing tees, standard tees with equal inlet and outlet diameters are also produced.

Branch Angles

Tees and reducing tees can be designed with different branching angles, such as:

  • 90° for perpendicular connections

  • 45° and 30° for smoother airflow and reduced pressure loss

  • Other angles depending on project requirements and system design

Features and Advantages

  • Adaptability to different inlet and outlet conditions

  • Better airflow control and reduced pressure loss with appropriate angle selection

  • Manufactured from galvanized steel, aluminum, or stainless steel

  • High strength and precise connection to spiral round ducts

  • Designed for easy installation with fewer supports and flanges required

Applications

  • Used in HVAC systems, air distribution ducts, and industrial ventilation

  • Suitable for changing airflow direction, splitting, or combining airflows

  • Capable of pre-fabrication and quick installation in complex duct networks
