Round Ventilation Tee 45°
A round galvanized steel ventilation tee 45° (also referred to as an angled tee or lateral branch) is a specialized fitting designed to create low-resistance directional junctions within an air distribution network. This component is widely utilized in supply and extract systems where secondary lines need to split or merge at an acute angle. Unlike standard 90-degree alternatives, the inclined 45-degree geometry guides the moving air mass along a natural trajectory, which drastically minimizes dynamic resistance, prevents system pressure drops, and eliminates localized turbulence noise within the ductwork.
This component is fabricated on automated industrial machinery from premium hot-dip galvanized sheet steel, grade DX51D, featuring a robust zinc coating mass of Z275 (275 g/m²). The sturdy steel frame retains its precise cylindrical profile under structural mechanical loads and provides exceptional resistance against atmospheric rust and moisture corrosion, ensuring decades of reliable service in civil, commercial, and industrial engineering projects.
Key Benefits of the Round 45° Ventilation Tee
- Airtight joint isolation without liquid mastics: The connection ports are equipped with factory-fitted double-lipped EPDM rubber gaskets that establish a dense, dual-contour seal against the inner walls of the ducts, effortlessly achieving an Airtightness Class D rating without requiring extra sealing tape.
- Rapid assembly without structural alignment errors: Sized with a calibrated male connection profile, the ports slide effortlessly into straight round ducts. Stamped center stop beads act as physical insertion barriers, accurately locking the depth of the joint and accelerating on-site installation.
- Safe job-site handling and reinforced stiffness: The collar edges are processed using machine-turned SAFE technology (up to D-400), which folds the raw rims inward to protect installers from accidental cuts and increases the radial rigidity of the ports against physical deformation.

Assembly and Jointing Recommendations
The ventilation tee utilizes a standard male connection layout for direct pipe-to-pipe integration. The collars slide inside standard straight round ducts until they sit flush against the physical stop beads, and the overlapping junction must be mechanically secured using blind rivets or self-tapping sheet metal screws. Due to the angled geometry of the fitting, precise axial alignment of the connecting lines is mandatory during assembly. If your layout requires attaching the tee directly to another molded fitting (such as an elbow), a female sleeve coupling must be implemented to bridge the node.
