Tee with Gasket ALNOR TPCL-100-100 — round duct branch 100 mm with sealing gasket

ALNOR TPCL-100-100 is a tee duct fitting with an integrated sealing gasket designed for round ventilation ducts with 100 mm diameter branches. The fitting creates a smooth, cylindrical branch connection from the main run and is intended for applications that require reduced air leakage and straightforward assembly. Constructed for compatibility with standard 100 mm round ducts, this tee supports HVAC air distribution, extraction and recirculation systems where airtight joints are important.

Advantages

The integrated sealing gasket reduces leakage at the branch junction, improving overall system efficiency and helping to maintain designed airflow rates. Its round profile matches standard ducting geometry for a compact, low-resistance airflow path. The simple push-fit assembly enables quick installation without additional sealing materials or special tools in many cases, and the gasket provides consistent pressure against the mating duct for repeatable joints.

Suitable for

• Residential and commercial ventilation systems with 100 mm round ducts
• Exhaust and kitchen extraction installations
• Indoor air recirculation and local distribution branches
• Retrofit projects requiring airtight branch connections

Key specifications

• Branch diameter: 100 mm (round)
• Type: Tee (branch connection from main run)
• Integrated sealing gasket for leak reduction
• Material: metal duct fitting compatible with standard round ducts
• Suitable for mechanical and natural ventilation airflow

How to use

Measure and cut the main duct and branch duct to the required positions, ensuring clean, square ends. Insert the branch end into the tee fitting until the gasket contacts the mating surface and the fitting seats securely. If required by the installation standard, use a mechanical clamp or screw fixing at the joint for added retention. Verify alignment and test the assembly for air tightness according to system commissioning procedures.

Usage recommendations

For best performance, ensure mating duct ends are free from burrs and contamination and push fully into the fitting until the gasket compresses uniformly. Inspect gasket condition before installation and replace the fitting if damage or deformation is present. Use appropriate supports for duct runs to avoid strain on the tee connection.
