The 120 to 110 mm vitreous enameled sleeve is an essential plumbing and heating fitting for ensuring a tight, safe, and efficient connection in flue systems. Specifically designed as a chimney pipe reducer , this fitting allows for the precise coupling of pipes of different diameters, optimizing draft and ensuring the proper functioning of wood or pellet stoves, boilers, and fireplaces.

Made with high-quality materials, this adapter features an exterior and interior vitreous enamel coating that provides excellent resistance to high temperatures, corrosion, and the acidic condensate generated during combustion. Its smooth finish not only facilitates easy cleaning and maintenance but also prevents soot buildup, significantly improving the durability of the entire flue system.

Frequently Asked Questions

What exactly is this vitrified sleeve used for?

This component acts as a reducer to safely connect two sections of chimney pipes with different diameters, going from 120 mm to 110 mm, ensuring that no gas or smoke leaks to the outside.

Is it suitable for wood and pellet stoves?

Yes, its vitrified design and high temperature resistance make it perfectly compatible with biomass heating systems, wood and other solid fuels that require approval and safety in the flue.

How is this reducer installed?

The sleeve fits directly between the corresponding pipes of the installation. It is recommended to use refractory sealant or high-temperature sealing agents at the joints to ensure a watertight seal and comply with current regulations.
