ALNOR NSL-100 Ventilation Sleeve with Gasket

The ALNOR NSL-100 ventilation sleeve with gasket is a precision-engineered component designed for the reliable connection of circular ventilation ducts. This sleeve facilitates a secure fit between pipes, ensuring the integrity of your HVAC system. Featuring an integrated high-quality rubber gasket, it provides an airtight seal that minimizes pressure loss and prevents unwanted air leakage throughout the ventilation network.

Advantages

The primary benefit of the ALNOR NSL-100 is its superior sealing capability, which is achieved through the factory-fitted rubber gasket. This design feature significantly reduces the time required for installation, as it eliminates the need for additional sealants or tapes. The robust construction ensures long-term durability and resistance to mechanical stress, making it a dependable choice for both residential and commercial ventilation projects. Its standardized dimensions allow for seamless integration into existing ductwork systems, promoting efficient airflow and system performance.

Suitable for

• Connecting circular ventilation ducts in residential buildings
• Commercial HVAC system installations
• Ventilation networks requiring high airtightness standards
• Extending or joining rigid duct segments

When it may not be suitable

This ventilation sleeve is specifically designed for circular ducting and is not compatible with rectangular or oval ventilation systems. It is intended for standard HVAC applications and may not be suitable for environments involving highly corrosive gases, extreme temperatures, or specialized industrial exhaust systems that require specific material certifications.

Key specifications

• Diameter: 100 mm
• Material: Galvanized steel
• Seal type: Integrated rubber gasket
• Compatibility: Standard circular ventilation ducts

How to use

To install the ALNOR NSL-100, simply insert the sleeve into the ends of the two circular ventilation pipes you wish to connect. Ensure that the sleeve is pushed in far enough so that the rubber gasket is fully engaged within the pipe ends, creating a firm and airtight seal. Once positioned, the connection can be further secured using self-tapping screws or rivets if required by local building codes or specific installation standards.

What to consider before purchase

• Verify the diameter of your existing ductwork matches the 100 mm specification
• Ensure the material compatibility with your current ventilation system
• Check local building regulations regarding duct connections

Usage recommendations

For optimal performance, ensure that the duct ends are clean and free of burrs before inserting the sleeve. Proper alignment of the pipes during installation will prevent unnecessary strain on the gasket and ensure a long-lasting, airtight connection.
