A cushioned P clamp with a 47.6mm inside diameter, sized to AN28 hose. Lines this large are found on serious transfer and cooling installations rather than ordinary engine plumbing, and their weight when full makes secure mounting essential rather than optional. The internal cushion prevents the metal band from abrading the hose cover and reduces the vibration passed into both the hose and the mounting point. Because the size suits any tube or bundle of matching outside diameter, it is also handy for routing large conduit and loom runs. Fix to solid structure, and match the clamp to the actual measured outside diameter of what you are securing.
