Nipple 250 galvanized with gasket NOCU250

Application and Function in Ventilation Systems

This component connects sections of spiral (spiro) ducts in mechanical ventilation systems, ensuring a tight seal thanks to the built-in gasket. Made from galvanized steel sheet in class Z275, it is designed for use in systems requiring corrosion resistance and mechanical durability. Its construction enables quick installation without the need for additional sealing materials, accelerating the installer's work and reducing the risk of errors during duct connections.

Key Structural Features and Compliance with Standards

The product is distinguished by the "B" mark, a legal requirement for ventilation components placed on the market after June 30, 2019. This ensures compliance with the stringent fire safety and quality standards imposed on ventilation system components. Galvanization with a coating thickness corresponding to class Z275 guarantees long service life even in environments with elevated humidity, typical of certain industrial or utility zones.

• The component is made of galvanized steel in class Z275, ensuring high resistance to rust.
• The built-in gasket eliminates the need for additional tapes or pastes when connecting ducts.
• Possession of the "B" mark is essential for legal sale and installation after 30-06-2019.
• The product is ideal for connecting spiral ducts in mechanical ventilation systems.

Practical Benefits for Installations

Choosing this nipple directly impacts the final quality of the installation. The gasket prevents air leakage from the ducts, which is crucial for maintaining the designed fan performance and the overall energy efficiency of the system. For professionals, this means less time spent correcting connections, while for investors it ensures the installation operates according to the design without pressure losses.

It is worth noting that although this component is standardly used to connect ducts with a diameter of 250 mm (as indicated by the model name), its universal design allows for efficient adaptation to the profile of spiral ducts, ensuring connection stability even at higher airflows. The Z275 galvanization class and the "B" mark are not just technical data but real guarantees of durability and compliance with construction regulations under current market conditions.
