Ventilation clamp 400 M8 thread. Quantity per package 25 pieces. 9400VIEL

Sound Insulation and Fire Resistance in One Element

The ventilation clamp 400 thread M8 (9400VIEL) is designed to combine effective acoustic insulation with fire resistance – without compromise. The EPDM rubber insert meets the requirements of DIN 4109, damping vibrations and sounds transmitted through ventilation pipes. This is not just insulation – it is practical noise reduction, particularly important in residential and public construction.

EPDM rubber not only provides excellent insulation but is also resistant to UV radiation and moisture – it does not crack or lose elasticity even after years of exposure to external conditions or within ventilation ducts. Additionally, it holds a B2 fire resistance certificate, meaning it meets basic fire safety requirements for components installed in ventilation systems.

Simple Installation, No Complications

The combined hexagonal head screw (Phillips + slotted) allows installation using either a standard screwdriver or a wrench – no need to search for specialized tools. The wide opening of the clamp facilitates fitting onto the pipe even with limited access. The screw length and conical shape ensure stable holding without the need for additional fastening.

The product carries an ITB approval – confirmation that it has been verified by a technical institution and meets the requirements of the Polish construction market. This is not a typical clamp – it is an element approved for use in facilities requiring documented compliance.

Precision for the Installer; Silence for the User

There is no need to additionally insulate the pipe – the clamp does it for you. There is no need to worry about the fire class of the material – B2 is already built in. Installation takes less time, as there is no need to fit additional components or use special tools. This is the solution for those who want to do it right the first time.
