Duct Tee MAGNAPLAST 125/125/45° for ventilation and ducting systems

MAGNAPLAST duct tee 125/125/45° for ventilation and ducting systems is a metal/plastic fitting designed to create a fixed-dimension junction where a 45° branch meets a main run. The fitting joins two 125 mm ducts and redirects airflow with a 45° branch angle, providing a compact solution for air distribution in HVAC and ventilation installations where a smooth angled split is required.

Advantages

The MAGNAPLAST duct tee combines corrosion-resistant metal and durable plastic components to balance strength and light weight. The 45° branch angle reduces abrupt flow changes compared with right-angle branches, contributing to steadier airflow and potentially lower pressure losses. Its standardized 125 mm duct diameter ensures compatibility with common ventilation pipes and accessories, simplifying integration into existing systems. The fixed-dimension design provides reliable alignment and a neat installation where space constraints or routing choices require an angled connection.

Suitable for

• Residential and commercial HVAC distribution where a 125 mm branch is needed
• Ventilation systems requiring an angled branch to avoid obstacles or fit limited space
• Air handling applications that benefit from reduced turbulence at a 45° junction
• Retrofit projects where compatible 125 mm ducts and fittings are already installed

Key specifications

• Nominal duct diameter: 125 mm for both main and branch
• Branch angle: 45° relative to the main run
• Material: combination of metal and plastic components for structural support and corrosion resistance
• Connection type: slip-fit ends compatible with standard round ventilation ducts of matching diameter
• Application: indoor HVAC and mechanical ventilation systems

How to use

Position the MAGNAPLAST duct tee between the main duct and the branch duct, ensuring both ends seat fully over the slip-fit connections. Align the 45° branch to the intended direction and secure joints according to local installation practice, using clamps, seals or duct tape as appropriate to maintain airtightness. Verify that the fitting orientation does not obstruct other components and that supporting brackets or hangers are used where necessary to prevent sagging or stress on connections.

Usage recommendations

For best performance, install the duct tee in straight, clean duct sections and avoid tight bends immediately adjacent to the 45° junction. Inspect and seal all joints to minimize leakage, and provide adequate mechanical support for long runs. Select components and sealing materials appropriate for the installed environment and operating temperatures.
