Almeva flue elbow 87° reducing DN60/80 UV-stable — PBBR58

Almeva flue elbow 87° reducing DN60/80 UV-stable — PBBR58 is a purpose-built flue and ventilation fitting that redirects airflow with a near-right-angle turn while reducing the duct diameter from DN80 to DN60. Constructed from UV-stable material, the elbow is intended for exposed runs where sunlight or outdoor conditions could affect standard plastics. The fitting provides a controlled change of direction and cross-section for exhaust gases or ventilation air in systems where space constraints or route changes require a compact reduction elbow.

Advantages

The reducing 87° design enables a tight directional change with an integrated diameter transition, minimizing the need for separate reducer and elbow components. UV-stable construction improves resistance to sunlight and weathering when used in outdoor or exposed sections. The smooth internal profile supports consistent airflow and reduces turbulence at the change of diameter. The product is compatible with DN60 and DN80 system components, allowing straightforward integration into mixed-diameter installations.

Suitable for

• Ventilation systems requiring a compact directional change with diameter reduction
• Flue and exhaust ducting where a near-90° turn is needed between DN80 and DN60
• Exposed external installations where UV resistance is required
• Retrofit or new-build applications connecting different pipe sizes

Key specifications

• Angle: 87° directional change
• Input diameter: DN80
• Output diameter: DN60
• Material property: UV-stable construction suitable for exposed use
• Application: for flue and ventilation airflows including exhaust gases

How to use

Install the reducing elbow in the duct run at the location where the direction change and diameter reduction are required. Ensure mating DN80 and DN60 pipes are clean, correctly sized and free of damage before assembly. Use the appropriate sealing and fastening method recommended for the system (for example, compatible clamps, seals or adhesive specified for the duct material) to achieve a gas-tight connection where required. Verify alignment and support the elbow to prevent strain on adjacent pipe joints and to maintain system slope or clearances defined by the installation standards.

Usage recommendations

Confirm compatibility with the ventilation or flue system materials and local codes prior to installation. For applications carrying combustion products, ensure the entire system is sealed, supported and installed according to relevant safety standards and manufacturer guidance. Regularly inspect exposed installations for UV or weathering effects and replace components if integrity is compromised.
