About this asset

Supplied as a Revit family, this round duct horizontal tee fitting provides a branch junction for circular mechanical ventilation runs. The fitting features a cylindrical straight run with a perpendicular cylindrical branch intersecting at ninety degrees, forming a classic horizontal tee configuration. Both the primary barrel and branch transition with subtle swaged collars or tapered slip-fit ends designed to receive circular ducting segments. Surface rendering presents a neutral grey finish consistent with standard sheet metal air distribution components. Clean geometric modelling ensures lightweight performance without extraneous polygons, rendering smoothly in both hidden-line technical diagrams and shaded isometric views for MEP documentation.

The download is a 92 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.

In Autodesk Revit, load this RFA file directly into your mechanical project or template as a duct fitting component. Connectors align with standard circular duct systems to maintain air distribution routing and flow calculation continuity. MEP technicians can integrate the fitting into duct routing preferences for automated insertion during layout drafting, or place it manually at intersecting centerlines in coordination plans and section details.

Engineered for building services engineering, this circular fitting is essential across commercial office fit-outs, industrial facilities, healthcare plantrooms, and multi-residential ventilation shafts. It coordinates exposed mechanical ceilings in contemporary open-plan spaces, educational facilities, and retail shells where spiral ductwork remains visible. The component suits technical coordination models, clash detection passes, tender drawings, and installation layouts alongside round spiral ducts, inline attenuators, and circular air diffusers.
