SpiroFlex adapter T white for round ducts 60/100 to 80/125

SpiroFlex adapter T white for round ducts 60/100 to 80/125 is a T-shaped transition fitting for round ventilation ducts that enables connection between ducts of different diameters. It provides a right-angle branch point allowing airflow to be split or redirected between a 60/100 mm duct and an 80/125 mm duct. The fitting is finished in white and is intended for use in residential and light commercial ventilation and exhaust systems where a compact diameter transition with a branch is required.

Advantages

The adapter offers a compact solution for transitioning between two common duct diameters while maintaining airflow continuity. Its T-shape simplifies branching installations and reduces the need for multiple separate fittings. The white finish makes it suitable for visible installations or where a neutral appearance is preferred. The design facilitates secure connections to round ducts and supports standard ventilation layouts.

Suitable for

• Connecting a 60/100 mm round duct to an 80/125 mm round duct
• Creating a right-angle branch in ventilation and exhaust systems
• Residential bathroom and kitchen extractor fan installations
• Light commercial HVAC duct runs requiring diameter transition

Key specifications

• Shape: T-shaped transition adapter
• Primary diameter connection: 60/100 mm (round)
• Secondary diameter connection: 80/125 mm (round)
• Colour: white
• Material: durable ventilation-grade material suitable for ductwork (neutral description)
• Application: ventilation and exhaust systems, duct branching and diameter transition

How to use

Position the adapter so that the larger and smaller duct ends align with the corresponding duct sections. Ensure duct ends are clean and free of debris before insertion. Slide each duct over the adapter ends and secure the connection using appropriate clamps, clips or sealing tape as required by the installation practice. Check alignment and sealing to maintain airflow efficiency and to prevent leaks.

Usage recommendations

Verify compatibility of connected ducts with the adapter diameters and use corrosion-resistant clamps in humid environments. For best airflow performance, avoid sharp bends immediately adjacent to the adapter and ensure that the branch orientation matches the intended airflow direction.

SpiroFlex adapter T white for round ducts 60/100 to 80/125 is intended for straightforward installation by HVAC professionals or competent DIY installers familiar with ductwork connections.
