The GV1200 duct increaser and reducer provides a seamless transition between six-inch and five-inch round ductwork. Engineered for residential, commercial, and industrial HVAC/R systems, this durable fitting ensures a secure, leak-resistant connection that helps maintain optimal airflow velocity. By adapting different duct sizes without creating unnecessary air turbulence, it supports the overall efficiency of heating, cooling, and ventilation setups.
Constructed from heavy-duty 26-gauge galvanized steel, this fitting offers superior corrosion resistance and long-term structural integrity. The robust gauge prevents crushing or flexing under typical system static pressure, making it an ideal choice for professional HVAC installers seeking reliable components. Its standard round configuration allows for clean alignment within rigid trunk lines, runouts, or exhaust venting layouts.
When purchasing duct fittings, verifying dimensions and gauge requirements ensures full compatibility with existing equipment and local mechanical codes. This reducer is suitable for applications requiring durable metallic transitions, such as forced-air heating lines, range hood exhausts, or dedicated ventilation loops. Review project submittals or consult an HVAC technician to confirm alignment with your airflow dynamics.
