Fire hydrants are made from strong, durable materials to withstand tough conditions. The body is typically made of cast iron or ductile iron, offering strength and resistance to environmental wear. Bronze or brass is used for internal components, such as valves and nozzles, because of their excellent corrosion resistance. Stainless steel is often used for bolts and fasteners to prevent rusting. Rubber gaskets and seals ensure a watertight closure. Modern hydrants may include composite materials or plastic for lighter, more corrosion-resistant parts. Epoxy coatings are applied to protect the hydrant from rust and harsh weather. These materials ensure fire hydrants are durable, reliable, and efficient in firefighting.
