Enlarger from ø80/125 to ø100/150 with elastomer seal

The Metaloterm UK expander is designed to create a seamless transition from a concentric flue system with a diameter of ø80/125 to ø100/150. This expander element features a pre-assembled elastomer seal, guaranteeing a secure and leak-free connection. Thanks to the use of 316 stainless steel with a 0.6 mm wall thickness, this element is extremely resistant to corrosion and high temperatures, making it suitable for modern condensing boilers with a closed combustion system.
