This specialized version of the Supra W2 is used in applications subject to vibration and/or great variations in temperature and which cause the components of a hose assembly to expand and contract. Thanks to the spring washer system, the Supra CT maintains constant pressure around the hose and prevents leakage. The beveled edges protect the hose from damage. The Supra CT clamp complies fully with the RoHs directive EU 20032/95/EC dated 1st July 2006. This clamp is generally fitted in high-powered diesel engines in construction machinery, trucks, buses, marine engines, military vehicles and diesel-powered generators as well as in various other industrial applications where expansion and contraction cause assemblies using standard clamps to leak. * The maximum application pressure can vary depending on the type of hose used and the geometry of the coupling.Patented Worldwide.
