Round Ventilation Y-Tee and Cross
A round galvanized steel ventilation Y-tee (pants-type splitter) and X-tee (duct cross) are advanced distribution fittings engineered to merge, split, or cross multiple airflow paths within a ventilation network. Unlike standard T-shaped models, these specialized components facilitate smooth duct distribution at complex node points of climate control systems. The Y-tee divides a main line into two independent branches at a smooth 45-degree angle, while the four-way cross enables a compact, single-plane intersection of four air channels.
These components are manufactured on automated production machinery from high-grade hot-dip galvanized sheet steel, grade DX51D, featuring a robust zinc coating mass of Z275 (275 g/m²). The rigid metal construction maintains its precise geometric profile under structural loads and is fully protected against corrosion when continuously handling moving humid air masses in civil, commercial, and industrial engineering projects.
Key Benefits of Advanced Duct Splitters
- Minimized aerodynamic resistance and reduced noise: The gradual 45-degree angled distribution in Y-shaped models guides the airflow along a natural trajectory, which significantly eliminates turbulence, unloads fan equipment, and ensures quiet system performance.
- Airtight joint isolation without sealing tapes: All connection collars come equipped with factory-fitted double-lipped EPDM rubber gaskets that tightly seal against the inner duct walls, reliably achieving an Airtightness Class D rating when properly assembled.
- Maximum overhead space optimization: Implementing a four-way cross (X-tee) eliminates the need for complex, multi-level duct crossovers. This saves critical ceiling height behind suspended grids and accelerates overall installation time.
- Precise mechanical alignment and safe handling: Stamped center stop beads accurately lock the insertion depth to prevent axial misalignment, while the collar edges feature machine-rolled SAFE technology (up to D-400) to reinforce the ports and protect installers from hand cuts.
Technical Specifications and Layout Options
Linear dimensions, installation tolerances, and diameter calibrations comply fully with European standards EN 1505:2000 and EN 1506:2007. The standard range for equal-cross-section Y-tees spans from 100 mm to 800 mm, while cross fittings are supplied in a range from 100 mm to 630 mm.

Assembly and Jointing Recommendations
These fittings utilize a direct-insertion layout where the male collars slide inside standard round ducts until they hit the mechanical stop beads. Secure the overlapping junction permanently using blind rivets or self-tapping sheet metal screws. For non-sealed versions used in systems requiring external field sealing, protect the joints additionally with self-adhesive aluminum duct tape. If a splitter must be connected directly to another molded fitting, use a female sleeve coupling to bridge the node.
