Duct Tee Piece with Gasket ALNOR TPCL-250-250 — round connection Ø250 mm

ALNOR TPCL-250-250 is a duct tee piece with gasket designed for HVAC systems. It provides a branch connection between round ducts with a 250 mm diameter and ensures airtight performance through an integrated gasket. The round connection Ø250 mm allows straightforward connection to existing circular ventilation runs and supports routing airflow to branches or secondary ducts while maintaining sealed airflow paths.

Advantages

The tee piece combines a rigid metal body with a resilient gasket to reduce air leakage at the junction. Its round Ø250 mm geometry matches standard circular ductwork dimensions, enabling fast installation without additional adapters. The integrated gasket simplifies assembly and improves long-term sealing performance compared with plain press-fit connections. The component is intended for use in ventilation and air distribution systems where reliable airtight branching is required.

Suitable for

• Branching air supply or extract lines in HVAC installations
• Connecting circular 250 mm ducts to secondary runs
• Ventilation routes in commercial and residential buildings
• Repairing or modifying existing round duct networks

Key specifications

• Connection shape: round
• Nominal diameter: 250 mm (Ø250)
• Configuration: tee piece with gasket for airtight joint
• Application: ventilation and air distribution
• Material: metal body with elastomeric gasket

How to use

Align the round ends of the tee piece with the mating Ø250 mm ducts. Ensure sealing surfaces are clean and free of debris before assembly. Push the ducts over the tee piece ends until the gasket seats evenly to create an airtight joint. If required, secure connections with appropriate clamps or fasteners recommended for metal ductwork to prevent movement. Verify alignment and sealing visually and with a pressure or leak test as appropriate for the installation.

Usage recommendations

For best performance, install the tee piece in a clean, accessible location and avoid overtightening clamps that could compress or displace the gasket. Use compatible Ø250 mm circular ducts and follow local HVAC codes and testing procedures to confirm airtightness after installation.
