Almeva chimney reducer DN80 to DN60, UV-stable black (model PBKA55)

Almeva chimney reducer DN80 to DN60 in UV-stable black is a flue connector designed to create a reliable transition between circular pipes of different diameters. The reducer adapts an 80 mm (DN80) chimney or ventilation outlet to a 60 mm (DN60) pipe, enabling secure joining of exhaust, ventilation or flue components. Constructed from UV-resistant material, the accessory is intended for outdoor and exposed installations where sunlight and weather resistance are required.

Advantages

The reducer provides a smooth diameter transition with a close fit to standard DN80 and DN60 circular pipes, reducing turbulence and leakage at the connection point. UV-stable construction helps prevent material degradation, colour fading and loss of mechanical properties when used outdoors. The simple one-piece form factor allows quick installation and requires no special tools for basic assembly, which makes it practical for residential and light-commercial ventilation and exhaust systems.

Suitable for

• Connecting DN80 chimney or flue outlets to DN60 pipes
• Residential wood stove, pellet or gas appliance flue adaptations (where applicable to system design)
• Ventilation duct transitions in lofts, attics and exterior walls
• Light-commercial exhaust systems with circular flue sections

Key specifications

• Material: UV-stable plastic composite suitable for outdoor exposure
• Colour: black, UV-resistant finish
• Connection type: circular spigot/socket transition from 80 mm to 60 mm nominal diameter
• Application: flue, chimney and ventilation pipe transition for exhaust and ventilation systems
• Installation: push-fit / slip-fit style connection compatible with standard DN80 and DN60 round pipes

How to use

Ensure both mating pipe ends are clean, dry and free from debris before assembly. Align the reducer so that the larger end seats onto the DN80 outlet and the smaller end mates with the DN60 pipe. Push the parts together with even pressure until a snug fit is achieved. Depending on the overall system requirements, sealants, high-temperature tape, or approved clamps may be applied to secure the connection and ensure airtightness. Verify correct alignment and support to avoid strain on joined sections.

Usage recommendations

Use this reducer only in systems and installations that permit the specific materials and diameter change; consult appliance documentation and local building or chimney codes when connecting appliances. For outdoor exposed runs, inspect joints periodically for UV-related wear and reapply mechanical fasteners or sealing materials if necessary.
