SpiroFlex pipe coupling for ø130 pipe, brand SpiroFlex, model Z13

SpiroFlex Z13 is a pipe coupling designed for connection of ø130 (130 mm) round ventilation and ducting pipes. It creates a mechanical joint that aligns pipe sections and maintains continuous airflow in HVAC and ventilation systems. The coupling is intended for use where a reliable, simple-to-install connection between 130 mm diameter ducts is required.

Advantages

The coupling provides a stable, radial connection that ensures proper alignment of round duct sections and helps preserve airflow efficiency. Its construction is optimized for quick assembly and secure fit, reducing the need for additional sealing materials in standard applications. The part is compact and designed to integrate smoothly into existing duct runs while minimizing resistance and turbulence at the joint.

Suitable for

• Connecting ø130 mm round ventilation ducts
• HVAC installations in residential and light-commercial buildings
• Repairing or extending existing 130 mm ductwork
• Ventilation systems requiring a mechanical pipe joint

Key specifications

• Compatible pipe diameter: 130 mm (ø130)
• Application: round ventilation and ducting pipes
• Function: mechanical coupling for alignment and airflow continuity
• Installation: intended for inline joining of duct sections

How to use

Ensure both pipe ends are clean and free of debris before assembly. Insert the pipe ends into the coupling until properly seated and aligned. Verify that the joint is flush and that the coupling engages both duct ends evenly. If the installation environment or local regulations require, apply appropriate sealing tape or sealant to the joint after assembly to enhance airtightness. Follow standard HVAC installation practices and check for leaks after the system is operational.

Usage recommendations

Use the coupling for mechanical connections of 130 mm round ducts in ventilation systems. For improved airtightness in critical applications, combine the coupling with industry-standard sealing tape or approved sealants and perform a leak test after installation. Avoid excessive force during assembly to prevent deformation of duct ends.
