Flue Pipe with Collar 0.25 m DN80/125 Almeva LIK (LPRK08)

Flue Pipe with Collar 0.25 m DN80/125 Almeva LIK (LPRK08) is a short connector segment designed for concentric flue systems with an outer/inner diameter combination of 125/80 mm. This 0.25 m flue piece functions as a compact joiner between concentric pipes, providing a standardized, mechanically secure connection for domestic and light commercial ventilation and exhaust installations. The product is intended for use where a short, robust collar section is required to complete or repair concentric duct runs and to maintain the correct alignment and spacing between inner and outer conduits.

Advantages

The flue pipe with collar offers a precise fit for DN80/125 concentric systems and simplifies installation by providing a ready-made short coupling segment. Its construction ensures stable axial alignment of inner and outer pipes and helps preserve the integrity of the concentric configuration. The compact length makes it suitable for tight spaces and for use as a replacement part in pre-existing assemblies without requiring additional modification of adjacent pipework.

Suitable for

• Concentric flue and venting systems using 80/125 mm diameters
• Domestic boilers, water heaters, and compact ventilation units requiring concentric connectors
• Light commercial exhaust installations where a short connector piece is needed
• Repair or retrofit of existing concentric pipe runs in limited spaces

Key specifications

• Length: 0.25 m
• Concentric diameters: inner 80 mm / outer 125 mm
• Type: flue pipe with collar (short connector segment)
• Compatibility: designed for use in concentric venting systems with 80/125 mm configuration
• Application: connector for ventilation and exhaust installations in domestic and light commercial settings

How to use

Position the flue pipe with collar between the adjoining concentric pipe sections, ensuring the inner and outer pipes align with the corresponding collar recesses. Push the component fully into place until the mechanical seating is achieved and any required seals or clamps (supplied or specified by the installation guidelines) can be applied. Verify axial alignment and secure the connection according to the ventilation system manufacturer’s mounting instructions and local regulations. Use appropriate sealing or fixation methods where necessary to maintain gas-tightness and mechanical stability.

Usage recommendations

Install and inspect this flue connector as part of a complete concentric system according to the appliance manufacturer’s instructions and applicable safety standards. Ensure compatibility with the overall system materials and operating temperatures. Periodically check joints for secure fit and signs of wear, and replace the segment if deformation or corrosion compromises the connection.
