Spiral Duct Y Branch with Rubber Gasket
Spiral duct Y branch, also known as round duct Y tee and Y junction connector, is an airtight ventilation fitting for splitting or combining airflow in circular spiral duct systems. Constructed from rust-resistant galvanized steel or stainless steel, this Y-shaped duct piece features built-in rubber gaskets to enhance sealing performance and simplify installation work. Its optimized curved Y structure reduces airflow resistance and pressure drop for stable air circulation. With multiple thickness and diameter options fully customizable, it fits all standard spiral duct sizes, serving as a core branch accessory for commercial buildings, industrial ventilation and household HVAC air distribution projects.
Product Description
The Spiral Duct Y Branch with Rubber Gasket is designed for efficient branch connection in round HVAC duct systems. Its Y-shaped structure allows airflow to be split or combined smoothly, helping reduce turbulence and pressure loss compared with traditional sharp-angle branch fittings.
Manufactured from stainless steel or galvanized steel, this fitting offers excellent strength, corrosion resistance, and long service life. The integrated rubber gasket improves airtightness, minimizes air leakage, and enables faster installation without additional sealing materials.
It is widely used in spiral duct systems for commercial, industrial, and residential ventilation applications, especially where reliable branch distribution and efficient airflow performance are required.
