The accessory is compatible as a replacement or for extending existing suction lines, helping maintain suction performance when installed correctly.

How to use

Usage recommendations

Use the hose within the intended wet and dry vacuuming applications; avoid suction of hot ashes, corrosive chemicals, or large sharp objects that could damage the hose or reduce service life. Regularly check for wear, cracks or obstructions and replace the hose if damage is found. For optimal suction performance, keep connections tight and avoid excessive kinking or compression of the hose.
