Exhaust Pipe Support Elbow 87° for Flue DN80, Polypropylene, up to 120°C, with Rail — Poujoulat

Support elbow for exhaust and flue systems by Poujoulat, designed with an 87° bend for DN80 (80 mm) ducting. Manufactured from polypropylene, this elbow is rated for continuous temperatures up to 120°C and includes an integrated rail for secure mounting. The component is intended to provide a compact angled connection while also supporting horizontal or slightly inclined sections of exhaust conduit in heating and ventilation installations.

Advantages

The polypropylene construction ensures chemical and corrosion resistance while keeping the part lightweight. The 87° angle allows near-right-angle direction changes in limited spaces without requiring additional couplers. The integrated rail adds mechanical support and simplifies installation by providing a stable mounting point, reducing strain on connected pipe runs. The temperature rating up to 120°C makes the elbow suitable for many residential and light-commercial flue applications.

Suitable for

• Routing DN80 exhaust or flue pipes around obstacles
• Supporting short horizontal flue sections with an integrated mounting rail
• Installing compact angle connections in residential and light-commercial heating systems

Key specifications

• Material: polypropylene
• Nominal diameter: DN80 (80 mm)
• Angle: 87°
• Maximum continuous temperature: up to 120°C
• Integrated support rail for mounting

How to use

Fit the elbow into the DN80 flue system at the required location, ensuring that connection ends are clean and free of debris. Align the elbow so the integrated rail contacts the mounting surface, and secure the rail with appropriate fasteners to a structural support or wall bracket following local installation rules. Ensure pipe joints are assembled according to the flue system manufacturer’s guidance to maintain airtightness and proper fall where required. Check clearances to combustible materials and verify that the installed orientation provides safe condensate drainage or gas flow as applicable.

Usage recommendations

Use appropriate fasteners and heat-resistant seals compatible with polypropylene and the system’s operating temperatures. Periodically inspect the support rail and joints for mechanical stress and seal integrity, especially after initial heating cycles.
