Almeva STARR 45° Elbow DN80 UV‑stabilized Black (PBSB48)

The Almeva STARR 45° Elbow DN80 UV‑stabilized Black is a 45-degree bend designed for DN80 duct and pipe systems. This component provides a compact directional change while maintaining a continuous internal profile compatible with ventilation, flue or exhaust routes. The black UV‑stabilized outer surface improves resistance to sunlight exposure for outdoor sections and helps preserve appearance and material properties over time.

Advantages

This elbow offers a precise 45° angle for controlled directional changes in DN80 systems, reducing turbulence and preserving flow characteristics compared with sharper bends. The UV‑stabilized black finish increases resistance to solar degradation, making it suitable for exposed installations. Its consistent internal geometry supports reliable connections and sealing with matching DN80 components, and the manufactured tolerances ensure repeatable fit and alignment in modular duct runs.

Suitable for

• Ventilation duct routing in residential or light-commercial systems
• Flue and exhaust direction changes where a 45° bend is required
• Indoor and outdoor piping runs that need UV resistance

Key specifications

• Nominal diameter: DN80
• Bend angle: 45°
• Color and finish: black, UV‑stabilized outer surface
• Application compatibility: ventilation, flue, and exhaust systems
• Construction: molded elbow with continuous internal profile for smooth flow

How to use

Install the elbow by aligning its sockets with the mating DN80 pipes or fittings and ensure a snug fit according to the system's connection method (push‑fit, adhesive, or mechanical coupling as applicable). Check orientation so the 45° deflection matches the intended routing. After assembly, verify seals and support the run to prevent undue stresses at the joint. For outdoor sections, position the UV‑stabilized side outward as needed to benefit from the engineered surface protection.

Usage recommendations

Ensure compatibility with the DN80 system type and follow local codes for ventilation or flue installations. Use appropriate sealing materials and supports to maintain alignment and prevent vibration or thermal movement from stressing the elbow. For outdoor exposure, periodic inspection is advisable to confirm continued integrity of seals and external surface.
