ALNOR CPSL-200 End Cap with Gasket for Ventilation Ducts

The ALNOR CPSL-200 end cap is a professional-grade ventilation component engineered to provide a secure and airtight seal for circular duct systems. Constructed from high-quality galvanized steel, this end cap is designed to close off unused duct branches or system terminals effectively. The inclusion of an integrated EPDM rubber gasket ensures a tight fit that minimizes air leakage, thereby maintaining the overall pressure and efficiency of your HVAC installation.

Advantages

This end cap offers exceptional durability and resistance to environmental factors, ensuring a long service life in various ventilation applications. The integrated EPDM rubber gasket is a significant advantage, as it eliminates the need for additional sealants and simplifies the installation process while guaranteeing high airtightness classes. Its robust steel construction provides structural integrity, preventing deformation during installation and operation. The design is optimized for quick and easy mounting, making it an ideal choice for both new HVAC projects and maintenance tasks.

Suitable for

• Sealing unused branches in circular ventilation ductwork
• Terminating duct runs in residential and commercial HVAC systems
• Maintaining airtightness in industrial ventilation networks
• Temporary or permanent closure of duct system components

This product may not be suitable for high-temperature industrial exhaust systems where temperatures exceed the thermal limits of the EPDM rubber gasket. Additionally, it is designed specifically for circular ducts and cannot be used on rectangular or oval ductwork systems.

Key specifications

• Material: Galvanized steel
• Seal type: Integrated EPDM rubber gasket
• Compatibility: Circular ventilation ducts
• Diameter: 200 mm

To install the ALNOR CPSL-200, simply slide the cap onto the end of the circular duct or into the fitting. Ensure that the surface of the duct is clean and free of debris to allow the EPDM gasket to seat properly. Push the cap firmly until it is fully engaged with the duct wall to ensure a secure, airtight connection.

What to consider before purchase

• Verify the exact diameter of your ventilation duct to ensure compatibility
• Check the temperature requirements of your specific ventilation system
• Ensure the duct end is free from sharp edges that could damage the rubber gasket

For optimal performance, ensure the end cap is fully inserted into the duct. Regularly inspect the connection during routine maintenance to confirm that the seal remains intact and that there are no signs of vibration-induced loosening.
