This circular duct end cap is a Revit family component designed for sealing HVAC ducting systems in mechanical engineering projects. The component is a simple, circular end cap intended for use with round ductwork systems. It features a standard profile designed to terminate a duct run, providing a clean, closed finish. The geometry is straightforward, consisting of a circular face with a connecting flange, rendered here in a neutral grey finish typical of standard metal ducting components. The family is structured with clear reference planes and parameter labels, visible in the preview, which allow for the adjustment of diameter and depth to match specific project requirements and duct sizes.

The download is a 266 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Users can load this RFA file directly into a Revit project or a mechanical template. Once loaded, the component functions as a standard duct fitting. It should be placed at the end of a duct run; the family is designed to snap to existing circular duct connectors, ensuring proper alignment within the mechanical system. Users can modify the dimensions via the properties palette or type properties to ensure the cap matches the specified duct diameter, maintaining accurate schedules.

This end cap is essential for mechanical engineers and BIM coordinators working on residential, commercial, or industrial HVAC system layouts. It is used during the design and construction documentation phases to seal off duct terminations, ensuring air tightness and accurate system representation in 3D models. It pairs perfectly with standard circular ductwork and transition fittings. Professionals looking for reliable mechanical components often search for duct accessories, round duct caps, or HVAC system fittings to complete their MEP model assemblies.
