Reducer
Stainless Steel Reducer for Flue Gas Ducts – Safe Transition to Smaller Diameter
Indispensable for renovation and modification of flue gas exhausts
The stainless steel reducer is an essential accessory for any chimney installer or HVAC technician who wants to connect a larger diameter flue to a smaller pipe. This transition coupling ensures a flue gas-tight, stable and safe connection, even in systems with slight overpressure (P1).
Manufactured from high-quality 316L stainless steel, this reducer is corrosion-resistant and can withstand high temperatures. Ideal for applications with condensing boilers, pellet stoves, wood stoves and other combustion appliances.
🛠️ Application of a stainless steel reducer:
• Connects for example a 130 mm flue gas pipe with a 110 mm connection
• Used when adapting or renovating existing chimney systems
• Suitable for both horizontal and vertical flue gas exhaust systems
• Compatible with single-walled stainless steel pipes or concentric systems
✅Main features:
✔️ Made from stainless steel 316L – high resistance to moisture, condensation and temperature
✔️ Flue gas-tight when used in P1 systems (200 Pa)
✔️ Easy installation thanks to standard socket/spigot connection
✔️ Available in various diameter combinations (e.g. Ø130 > Ø110, Ø100 > Ø80…)
✔️ Perfect for use in Belgium with all common boilers and chimneys
