## Long description

SpiroFlex 125/125 T125/125-OC is a 90° galvanized duct branch (T-piece) designed for circular ventilation and HVAC systems. The component allows splitting or joining two 125 mm circular ducts into a main run at a right angle, providing a robust metal connection for air distribution and extraction. Galvanized steel construction offers mechanical rigidity and resistance to corrosion in typical indoor environments.
Advantages
The galvanized metal body provides durable structural support and consistent airflow through joined duct sections. The 90° geometry is optimized for compact installations where a perpendicular branch is required. The product is compatible with standard 125 mm circular ducts and supports secure, leak-minimized connections when installed with appropriate sealants or clamps.
Suitable for
Residential ventilation systems for supply or exhaust air
Commercial HVAC branch connections and duct routing
Kitchen and bathroom extractor ducting where a 90° branch is needed
Retrofit projects requiring a rigid T-piece for circular ducts
Key specifications
Connection diameter for branch lines: 125 mm
90° branch angle for perpendicular duct connection
Material: galvanized steel for corrosion resistance and rigidity
Application: circular ventilation and HVAC systems
Suitable for indoor installations in residential and commercial buildings
How to use
Position the T-piece where the main duct run and perpendicular branch meet, ensuring correct alignment of the 125 mm circular ends. Prepare the duct ends by removing burrs and applying an appropriate sealing tape or silicone if required. Fit the ducts onto the T-piece ends and secure with approved clamps or screws, observing manufacturer torque recommendations for metal duct connections if available. Verify alignment and airtightness after installation, and support the assembly with hangers or brackets as necessary to avoid strain on the joints.
Usage recommendations
For reliable long-term performance, install the duct branch in environments free from aggressive chemicals and prolonged moisture exposure. Where higher corrosion resistance is needed, consider additional protective coatings or alternative materials. Ensure airflow capacity and pressure drop are checked when adding branches to avoid compromising system performance.
