SpiroFlex connection duct SpiroFlex 80, 0.25 m length, model SX-PEL80R025

The SpiroFlex connection duct SpiroFlex 80, 0.25 m length, model SX-PEL80R025 is a short rigid connector intended for ventilation systems with a nominal diameter of 80 mm. It provides a compact link between duct sections or between a duct and a fitting, ensuring proper alignment and allowing secure airflow transfer in residential and light-commercial HVAC installations. The construction combines metal and plastic elements as specified by the manufacturer to balance strength and ease of installation.

Advantages

This SpiroFlex connection duct offers a precise fit for Ø 80 mm ventilation runs and a fixed 0.25 m length that simplifies layout planning in confined spaces. Its rigid form maintains alignment between adjoining components and reduces the risk of air leakage when installed with appropriate seals and clamps. The mixed metal/plastic construction reduces weight while preserving structural stability and resistance to deformation under normal operating conditions.

Suitable for

• Joining two Ø 80 mm duct sections in domestic ventilation systems
• Connecting Ø 80 mm ducts to fittings, bends or silencers
• Short rigid connections in kitchen, bathroom or utility room extract systems
• Light-commercial HVAC runs where a compact, fixed-length connector is required

Key specifications

• Nominal diameter: 80 mm
• Length: 0.25 m (250 mm)
• Construction: combined metal and plastic components (manufacturer specified)
• Application: rigid connection for ventilation ducts and fittings

How to use

Insert the SpiroFlex connection duct into the mating duct ends or fitting sockets, ensuring the alignment marks and ends are flush. Secure each end with appropriate clamps or sealing tape to achieve an airtight joint. Verify that the duct run is supported and that the connector does not bear structural loads beyond its intended purpose. Follow any additional manufacturer instructions for compatible sealants or fastening methods.

Usage recommendations

For reliable performance, use compatible Ø 80 mm clamps and duct sealant appropriate for mixed metal/plastic components. Avoid excessive bending or applying axial loads to the connector; provide support at nearby duct sections to prevent stress. Inspect joints after installation and during routine HVAC maintenance to confirm seals remain intact and air leakage is minimized.
