Product information

Description

The ALNOR NSL-160 is a professional-grade ventilation sleeve engineered for the secure connection of circular air ducts. Constructed from high-quality galvanized steel, this fitting is designed to maintain structural integrity within HVAC systems. It features an integrated EPDM rubber gasket that provides a reliable airtight seal, which is critical for maintaining system pressure and preventing air leakage in both residential and commercial ventilation networks.

Advantages

The primary benefit of the ALNOR NSL-160 is its superior sealing capability, which significantly reduces energy loss and minimizes noise generated by airflow turbulence. The inclusion of the EPDM gasket simplifies the installation process by eliminating the need for additional sealants or tapes, ensuring a tight fit that meets industry standards for airtightness. Its robust steel construction offers long-term durability and resistance to environmental factors, making it a dependable choice for demanding ventilation projects.

Suitable for

Connecting circular ventilation ducts in residential buildings
Commercial HVAC system installations
Industrial ventilation ductwork configurations
Systems requiring high airtightness standards

When it may not be suitable

This sleeve is specifically designed for circular ducting and is not compatible with rectangular or oval ventilation systems. It is also not intended for use in environments with extreme chemical exposure or temperatures that exceed the operational limits of the EPDM rubber gasket.

Key specifications

Diameter: 160 mm
Material: Galvanized steel
Gasket type: Integrated EPDM rubber
Compatibility: Circular air ducts

How to use

To install the ALNOR NSL-160, simply insert the sleeve into the ends of the two circular ducts you wish to connect. Ensure that the duct ends are clean and free of debris to allow the EPDM gasket to seat properly. Push the ducts firmly onto the sleeve until they reach the center stop. The integrated gasket will automatically create an airtight seal, securing the connection without the need for extra tools or sealing materials.

What to consider before purchase

Verify that your duct diameter is exactly 160 mm
Ensure the system layout allows for standard circular fitting connections
Check the temperature requirements of your specific HVAC project

Usage recommendations

For optimal performance, ensure that the duct edges are free of burrs before insertion to prevent damage to the EPDM gasket. Regularly inspect connections during routine HVAC maintenance to ensure the integrity of the seal remains intact over time.
