A cushioned P clamp with a 38.1mm inside diameter, sized for AN20 hose. At the top of the automotive AN range the hose is heavy even before it is filled, and every unsupported metre of it puts load on the fittings at each end. Clamping it properly protects those joints as much as it protects the hose cover, and the internal cushion keeps the band from wearing through the outer braid or jacket while damping vibration. Typical use is on large dry-sump, cooler and transfer plumbing. Anchor to solid structure rather than sheet panels, and allow a short free length near each fitting so the hose can flex naturally.
