This clip was specially designed for use with hoses incorporating an outer helix. It is generally used when installing ventilation ducting or in white goods applications. The double-wire construction of this clip means that it sits comfortably on either side of the helix and can then be clamped down firmly thanks to the screw-tightening system. * The maximum application pressure can vary depending on the type of hose used and the geometry of the coupling. * Special diameters are available on request.
