A duct collar or flange is a connecting component used to join duct sections or attach ducts to hood bodies/enclosures in industrial ventilation systems.
A duct collar or flange is a standardized mechanical interface component designed to create secure, airtight connections between ductwork sections or between ducts and hood bodies/enclosures in industrial ventilation and exhaust systems. It typically consists of a circular or rectangular collar with bolt holes or clamping mechanisms that align with mating flanges on adjacent components, ensuring proper alignment and sealing to maintain system integrity and prevent air leakage.

A duct collar typically refers to a short cylindrical extension with a rolled edge for slip-on connections, while a flange is a flat, bolted interface with standardized bolt patterns. Collars are often used for flexible connections, while flanges provide rigid, high-pressure connections.
Select gasket material based on temperature range, chemical exposure, and pressure requirements. Neoprene for general use (-40°C to 100°C), silicone for high temperatures (-60°C to 230°C), and EPDM for weather resistance and chemical compatibility.
