ELEMENT T-STUK KST-400 R=300 HDG

The ELEMENT T-PIECE KST-400 R=300 HDG is a high-quality T-shaped duct fitting designed for circular HVAC systems. It enables a 90-degree branch connection from a main duct with a diameter of 400 mm, maintaining the same diameter for the branch. The fitting features a bend radius of 300 mm for smooth airflow transition, reducing pressure drop. Made from steel with hot-dip galvanized (HDG) surface treatment, it offers excellent corrosion resistance and durability for indoor and protected outdoor environments. Compliant with EN 1506 and leakage class C (EN 1507), it is suitable for low to medium pressure ventilation systems.

Advantages

This T-piece ensures efficient air distribution with minimal resistance, thanks to its optimized geometry. The HDG coating provides long-lasting protection against rust and environmental factors, making it a reliable choice for demanding HVAC applications. Its push-fit, rivet, or screw installation with sealant allows for secure and airtight connections.
