135° chimney tee SOLINOX Ø180 (inox 316L)

The 135° chimney tee SOLINOX Ø180 made of stainless steel inox 316L is a reliable single-wall flue component for connecting a side branch into the main vertical stack. The 135° geometry is chosen when the priority is the smoothest possible draft with minimal turning losses: flue gases change direction more gradually than in a 90° tee, so the system typically reaches stable operation faster and behaves more consistently during start-up.

The key advantage of the inox 316L version is increased resistance to aggressive environments and acidic condensate. This stainless-steel grade is especially relevant for applications with frequent start/stop cycles, lower flue-gas temperatures, and fuels that can produce more “acidic” condensate. As a result, the tee retains its working characteristics and appearance for longer, even with elevated moisture inside the channel. The 0.5 mm wall thickness provides strength, precise geometry, and stable joints under heat.

The SOLINOX Ø180 tee fits chimney systems of varying complexity: from straightforward stove/boiler connections to refurbishment of existing runs where a neat tie-in to the vertical riser is required. The single-wall design is most commonly used in heated spaces, in shafts, liners/sleeves, or as an insert element inside a masonry flue. The 180 mm diameter is selected according to the appliance outlet and the flue design calculation — correct sizing directly affects draft and safety.

Installation is carried out via a socket (spigot-and-socket) connection. This joint type speeds up assembly, simplifies alignment, and helps achieve a tight fit. It is important to assemble components in the direction of flue-gas flow and follow general installation rules: secure joints with clamps, use heat-resistant sealing materials (if permitted by the system manufacturer), and allow for thermal expansion compensation.

The lower section of the tee is a mandatory service zone. Beneath the tee, an inspection section for cleaning, an end cap, or a condensate collector is installed. This layout simplifies routine maintenance, allows soot build-up to be monitored, and enables timely moisture removal, reducing the risk of corrosion and blockages. In systems where cleanliness and stable operation matter, this configuration is considered a practical standard.

If you need a tee that performs reliably under higher humidity and potentially aggressive condensate, the Ø180 inox 316L version is an optimal choice. It combines a 135° angle for better draft behavior, a robust build, and an added corrosion-resistance margin that is especially valuable over long-term use.
