Spiral Duct Y Branch without Gasket
Galvanized Steel Spiral Duct Y Branch without Gasket for HVAC Ventilation Systems
Galvanized spiral duct Y branch without gasket, designed for efficient airflow splitting and branch connections in round HVAC duct systems.
Product Description
The Spiral Duct Y Branch without Gasket is designed for branch connections in round HVAC duct systems. Its Y-shaped configuration allows airflow to split or combine more smoothly than standard 90° branch fittings, helping reduce turbulence and improve airflow efficiency.
Manufactured from galvanized steel, this fitting offers reliable structural strength, corrosion resistance, and long service life. The non-gasket design is suitable for projects requiring standard mechanical duct connections or additional sealing treatment during installation.
It is widely used in commercial, industrial, and residential ventilation systems for air supply, exhaust air, and general duct branching applications.
