Flue Adapter Almeva FLEX Adapter STARR/FLEX DN 60, model PPAES5

Almeva FLEX Adapter STARR/FLEX DN 60 is a DN 60 flue and duct adapter designed to connect STARR rigid components with FLEX flexible ducting. The adapter creates a secure transition between rigid and flexible elements in ventilation, exhaust and chimney systems, allowing straightforward integration in residential and light-commercial HVAC installations. Manufactured by Almeva, this adapter is intended for use where a reliable, dimension-matched connection is required between DN 60 rigid and flexible ducts.

Advantages

The adapter provides a precise DN 60 interface that ensures stable mechanical connection and reduces the risk of leaks at the junction between rigid and flexible ducts. Its form and dimensions allow fast installation without custom modification of existing ductwork. Compatible design reduces vibration transfer and supports continued airflow performance across the joint. The component is suitable for repeated assembly and disassembly for maintenance or inspection.

Suitable for

• Connecting DN 60 rigid flue or duct sections to DN 60 flexible ducting
• Residential ventilation and exhaust systems
• Light-commercial HVAC and chimney connections
• Retrofit projects where existing rigid ducts must be joined to flexible runs

Key specifications

• Nominal diameter: DN 60
• Function: Adapter for transition between rigid and flexible ducts
• Application: Ventilation, exhaust and chimney ducting
• Compatibility: Designed to match STARR rigid and FLEX flexible duct profiles of the same nominal diameter
• Intended use environments: Residential and light-commercial HVAC systems

How to use

Position the adapter so that the STARR side engages the rigid duct and the FLEX side accepts the flexible duct. Ensure both mating ends are clean and free of debris before assembly. Push the rigid duct fully onto the adapter until it seats, then secure with the appropriate clamp or fastening method recommended for the duct material. Attach the flexible duct to the FLEX side, expanding or compressing the flexible material as needed to achieve a snug fit, and fasten with a clamp or tape compatible with the duct type. Verify alignment and airflow path, and inspect the connection for any gaps or misalignment prior to commissioning.

Usage recommendations

Use this adapter only with DN 60 duct systems and components of compatible profiles. For installations in combustion or high-temperature flue systems, verify the adapter material and system ratings meet applicable local codes and manufacturer instructions. Regularly inspect joints for secure fastening and signs of wear, and perform maintenance or replacement if the seal or mechanical fit degrades.
