SpiroFlex coupling DN 160 SpiroFlex Z160-OC

SpiroFlex coupling DN 160 SpiroFlex Z160-OC is a round duct coupling intended for connecting ventilation ducts with a nominal diameter of 160 mm. The fitting ensures a continuous air path and a mechanically stable joint between two circular duct sections, making it suitable for installation, repair or extension of HVAC ductwork in residential and commercial buildings. Constructed for compatibility with standard 160 mm round ducts, this coupling supports straightforward assembly and reliable airflow transfer without introducing significant resistance.

Advantages

The coupling provides a secure mechanical connection that resists axial separation and maintains alignment of joined ducts. Its design minimizes leakage when properly installed and helps preserve system performance by maintaining a smooth internal profile. Lightweight and compact, the coupling simplifies handling during installation and enables quick replacement or adjustment in confined spaces. Materials and form factor are chosen to be compatible with common ductwork components and mounting methods.

Suitable for

• Connecting round ventilation ducts with nominal 160 mm diameter
• Repairing damaged or corroded sections of duct networks
• Extending existing HVAC duct runs during renovation or retrofit
• Residential and commercial ventilation systems

Key specifications

• Nominal duct diameter: 160 mm
• Shape: circular/round coupling
• Function: mechanical connection for ventilation ducts
• Compatibility: designed for standard 160 mm round HVAC ducts
• Installation: intended for inline joining of two duct sections

How to use

Ensure both duct ends are clean, free of sharp edges and sized correctly to accept the coupling. Slide the coupling into or over the ends of the two duct sections according to the coupling fit (male or female), align the ducts to maintain airflow path, and secure the joint using clamps, screws, or other fastening methods appropriate for the duct material and system requirements. Sealant or gasket material may be applied where required to reduce leakage. Verify alignment and mechanical stability, then test airflow to confirm continuity and acceptable performance.

Usage recommendations

Use corrosion-resistant fasteners for systems exposed to moisture or humid environments. When aiming for improved airtightness, combine the coupling with approved duct sealants or sealing tape and follow local ventilation standards for connections and sealing procedures.
