Symmetrical galvanized reducer 150/125 with gasket RSOCU150125

Symmetrical reducer with gasket for mechanical ventilation systems

Made from galvanized steel sheet, designed for connecting ducts with diameters of 150 mm and 125 mm. The integrated gasket ensures airtight joints without the need for additional sealing — a key advantage when installing in hard-to-reach areas where there is no space for extra materials.

The "B" marking on the product indicates compliance with requirements effective from June 30, 2019 — meaning it meets current regulations for ventilation components in buildings. There is no need to worry about technical documentation: this is not an "add-on," but a standard.

Why does it perform well in practice?

• Galvanization — more than just appearance. Protects against moisture and corrosive factors inside ducts, where condensation and dust are normal. Rust does not develop, eliminating the need to replace components after a few years.
• Symmetry — no "front" or "back." Installation is faster because the reducer can be rotated as needed — no need to search for the correct orientation. This saves the installer time and eliminates errors.
• Integrated gasket — no need to purchase additional gaskets or install them manually. Reduces the risk of installation errors and minimizes the number of components on the work site.
• Weight 0.17 kg — lightweight yet robust. Easy to lift, transport, and hold with one hand while pressing it onto the duct.

There are no "magical" properties here. It is a simple, solid component — exactly what you need when you want the installation to operate trouble-free for years.
