ABS Y-Shape Tee Flange-Fresh Air Exchanger Reducer Duct Connector | Huaqi

Thickened ABS Y-shape tee flange features a split assembly structure, including a Y-tee body and a pre-drilled base flange. It can be installed as a complete unit or used without the base flange. Available in black and gray, it covers common reducer sizes 150-to-100 and 100-to-75, suitable for fresh-air exchangers, PE ducts and various ventilation systems. The thick one-piece injection-molded wall provides tight sealing and reduces air leakage. Smooth internal airflow path lowers resistance and improves split-ventilation efficiency for residential fresh air and commercial HVAC projects.
