Round Ventilation Tee 90° with Seal
A round galvanized steel ventilation tee 90° is an essential ducting component designed to create a strict perpendicular branch from a primary mainline run. This T-shaped fitting allows installers to efficiently distribute supply or extract air streams into individual rooms or merge multiple secondary lines into a single centralized network. Integrating a calibrated 90-degree tee simplifies complex duct routing layouts, eliminating the need for bulky, custom-built transitional nodes and optimizing overall system airflow.
This component is fabricated on automated machinery from high-grade 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 shape under structural mechanical loads and provides exceptional resistance against atmospheric rust and moisture corrosion, ensuring decades of reliable service in commercial, residential, and industrial air networks.
Key Benefits of the Round 90° Ventilation Tee
- Airtight joint isolation without liquid mastics: The connection collars are equipped with factory-installed 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: The calibrated male connection profile is engineered for straightforward pipe-to-pipe coupling. 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.
Technical Specifications and Custom Options
The linear dimensions, installation tolerances, and nominal port calibrations align fully with the European standard EN 1506:2007. The standard range covers equal-cross-section diameters: 100, 125, 160, 200, 250, 315, 400, 500, 630, 710, 800, and 900 mm.

Assembly and Jointing Recommendations
The ventilation tee utilizes a standard double-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. If your layout requires attaching the tee directly to another molded fitting (such as an elbow or a reducer), a female sleeve coupling (duct coupler) must be implemented to bridge the node.
