Rubber gasket for duct DN75

A thin rubber gasket is designed for a tight connection between the duct and the diffuser box. It is pressed between the diffuser box connection and the flexible duct, ensuring air tightness and vibration and sound attenuation. Gaskets are usually made of elastic rubber that is resistant to temperature fluctuations and aging. During installation, they are simply pressed into the diffuser box socket before connecting the duct.
