It prevents the hoses from dragging on the road, protecting them from abrasion and damage. Made from high-tensile spring steel with a zinc-plated, yellow dichromate finish to resist corrosion, it has double-looped ends that hook into hanger brackets. You typically replace it when the spring rusts, breaks, or loses tension, causing the hoses to sag.
