The Darley Large Diameter Hose (L.D.H.) is a high-performance, 5" rubber-covered fire hose designed for superior water flow and durability in demanding environments. Engineered with a nitrile/PVC through-the-weave construction, it expands under pressure to reduce friction loss and maximize water delivery. Its ribbed outer cover enhances resistance to abrasion, punctures, and impact, making it ideal for industrial firefighting, dewatering, and construction site washdowns.
