SpiroFlex flue pipe 80 mm polypropylene 0.25 m

SpiroFlex flue pipe 80 mm polypropylene 0.25 m is a short, solid-section connector designed for use in flue and ventilation systems that accept 80 mm ducting. Manufactured from polypropylene, this 0.25 m length pipe provides a compact extension or joining element for exhaust and venting installations in residential and light commercial environments. Its smooth internal surface supports steady airflow while the material selection ensures resistance to common corrosive agents and condensate typically encountered in flue applications.

Advantages

The polypropylene construction offers chemical and corrosion resistance, reduced weight compared with metal alternatives, and thermal stability adequate for typical ventilation and exhaust temperatures. The 80 mm diameter maintains compatibility with standard duct fittings of the same nominal size, enabling straightforward integration. The short 0.25 m form factor makes it convenient for tight spaces, short runs, or as a repair/replacement piece where minimal additional length is required.

Suitable for

• Connecting or extending 80 mm flue and ventilation ducts in homes
• Patching short gaps in exhaust lines for boilers, water heaters, or range hoods
• Installation in light commercial ventilation systems with 80 mm ducts
• Applications where chemical resistance and low weight are preferred over metal piping

Key specifications

• Material: polypropylene
• Nominal internal diameter: 80 mm
• Length: 0.25 m
• Design: straight flue/vent connector
• Surface: smooth internal bore for unobstructed airflow

How to use

Measure the required run and ensure compatibility with existing 80 mm ductwork before installation. Cut mating duct ends square and clean any debris. Slide the pipe into compatible fittings or duct sections using the appropriate coupling or seal recommended for polypropylene ducts. Ensure joints are secured and sealed according to local ventilation and flue installation standards to prevent leaks and maintain safe exhaust flow. For confined installations, handle the lightweight pipe carefully to avoid deformation during assembly.

Usage recommendations

Use this polypropylene flue pipe in systems operating within the temperature and chemical exposure limits of polypropylene. Avoid direct exposure to open flames or continuous high temperatures beyond the material’s rated thermal range. Follow local building codes and manufacturer guidance for sealing, support spacing, and use with other materials to ensure a safe and compliant ventilation or flue installation.
