What is the minimum thickness required for a vent connector made of galvanized steel?

The minimum thickness required for a vent connector made of galvanized steel is No. 28 gage. This standard ensures that the vent connector can withstand the operational conditions it faces, such as temperature variations, pressure, and moisture, while also being durable enough to resist corrosion over time. Galvanized steel is often specified for vent connectors due to its resistance to rusting, and using a thickness of No. 28 gage provides an adequate balance between strength and weight, making it suitable for effective ventilation in HVAC systems.

Choosing a gauge that is too thin could risk structural integrity and performance issues, which could lead to potential safety hazards or system failures. Therefore, adhering to the No. 28 gage specification is crucial for ensuring reliable and safe operation of the HVAC system.
