Product information

Description

SpiroFlex 125 złączka (oc) is a circular duct coupling designed for 125 mm round ventilation ducts. It provides a secure mechanical connection between sections of spiral or round ducts, maintaining alignment and continuity of airflow in ventilation systems. The coupling is intended for use in HVAC installations where a reliable 125 mm diameter joint is needed for repair, extension or reconfiguration of ductwork in residential and commercial environments.

Advantages

The coupling delivers a simple, fast method to join two lengths of 125 mm round duct without the need for specialised tooling. Its construction ensures a tight fit that reduces airflow leak points and helps preserve system efficiency. The part is compatible with standard spiral and round duct profiles of the same nominal diameter, enabling straightforward integration into existing ductwork runs. The design supports repetitive assembly and disassembly for maintenance or reconfiguration tasks.

Suitable for

  • Joining 125 mm spiral or round ventilation ducts
  • Repairing damaged duct sections in HVAC systems
  • Extending duct runs in residential ventilation
  • Connecting ducts in light commercial HVAC installations

Key specifications

  • Nominal diameter: 125 mm
  • Type: circular duct coupling for round/spiral ducts
  • Function: mechanical joint to align and connect duct sections
  • Compatibility: designed for standard 125 mm round duct profiles
  • Material: corrosion-resistant metal suitable for ventilation use

How to use

Slide each end of the coupling over the mating ends of the 125 mm ducts, ensuring the spiral or round profiles engage evenly. Align the ducts so the airflow path is smooth and the coupling sits squarely around the joint. Secure the connection using appropriate fasteners or clamp methods compatible with the duct material and local installation practice. After assembly, check for gaps and, if necessary, apply suitable sealing tape or sealant to reduce leakage.

Usage recommendations

Use the coupling with ducts of the same nominal diameter and compatible profile. Inspect the joint after initial operation and during regular maintenance to ensure fasteners and seals remain intact. For installations requiring airtight performance, complement the mechanical joint with HVAC-rated sealing methods and follow applicable ventilation standards.
