## Summary description

ALNOR TPCL-315-315 is a T-piece duct connector with integrated gasket designed for ventilation and air distribution systems. The TPCL-315-315 provides a DN315 branch connection, ensuring a sealed joint between circular ducts. Suitable for HVAC installations, air handling units, and ductwork modifications where reliable airtight connections are required.

## Long description

ALNOR TPCL-315-315 is a T-piece duct connector with integrated gasket, designed to join three circular ventilation ducts with a DN315 branch connection. Manufactured for HVAC systems, the TPCL-315-315 provides a sealed joint between main and branch ducts to reduce air leakage and maintain system pressure. The connector is intended for use in air distribution networks, air handling units and ductwork modifications where a reliable airtight connection is required.
Advantages
The integrated gasket ensures consistent sealing at each joint without separate sealing materials, simplifying installation and improving long-term airtightness. The T-piece design provides a standardized DN315 branch connection compatible with circular ducts, enabling straightforward integration into existing ductwork. The product’s construction is intended for duct systems where durability and repeated assembly or disassembly may be necessary.
Suitable for
 HVAC installations and new ductwork assemblies
 Air handling units and distribution branches
 Repairing or modifying existing circular ducts with DN315 diameter
 Systems requiring reduced air leakage and controlled airflow
When it may not be suitable
This T-piece is designed specifically for circular ducts with a DN315 connection; it is not suitable for duct sizes other than DN315 without adapters. It may not be appropriate for systems that require non-gasketed rigid metal connections, specialized acoustic silencers, or components with integrated dampers if those functions are required at the branch point.
Key specifications
 Connection type: T-piece with integrated gasket
 Nominal diameter: DN315 for main and branch ducts
 Application: ventilation and air distribution systems
 Function: provides sealed branch connection to reduce air leakage
 Material: designed for ductwork environments (metal construction compatible with circular ducts)
How to use
Position the T-piece so that the main ductlines and the branch DN315 connection align with the corresponding duct ends. Ensure gasket surfaces are clean and undamaged before assembly. Insert the duct ends into the connector until seated; the integrated gasket forms the seal. Secure the joints according to local HVAC practice, using clamps, screws or support brackets as required to prevent movement. Inspect the assembled joints for visible gaps and test the system for leakage and pressure balance after installation.
What to consider before purchase
 Confirm duct diameter is DN315 for both main and branch connections
 Check compatibility with existing duct material and jointing methods
 Ensure the integrated gasket type meets temperature and chemical exposure requirements of the system
 Consider whether additional supports, clamps or adapters are required for installation
Usage recommendations
For best performance, store the connector in a dry environment prior to installation, inspect gaskets for damage, and follow standard HVAC sealing and support practices. After fitting, perform a leakage test and balance the ventilation system to ensure the branch performs as intended.
