This is a semi-rigid hose which stays put when bent into shape. Amongst its various properties is its ability to change diameter over a range of about plus or minus 20mm when twisted in either clockwise or anti-clockwise directions. This means that a short length suitably adjusted for diameter can be used to adapt between hoses and machine outlets of different sizes. Another useful application is as a dust collector on a lathe or a bench-mounted machine with a short length of the hose being connected to the end of the extractor hose and positioned close to where the dust is generated. Available in grey, choose from a selection of diameters in lengths of 1 metre.
