Which layer of the 5 inch hose is described as the outer, durable, and ribbed layer?

• A. Inner layer
• B. Polyester reinforcement
• C. Outer layer
• D. Middle layer

Answer: (C)

In hose construction there are three main parts: the smooth inner lining that carries water, a reinforcement layer that provides strength and holds the pressure, and the outer protective cover. The outer cover is crafted to be durable against abrasion and the elements, and it’s commonly ribbed to resist wear and to give better grip when handling the hose. So, the layer described as outer, durable, and ribbed is the outer cover. The inner lining is the water-contacting surface, the reinforcement adds strength, and the middle layer (if present) is not the outer protective ribbed surface.
