What property does the polyester reinforcement provide in the 5 inch hose?

• A. Increased flexibility
• B. High tensile strength with minimal expansion and non-absorbency
• C. Heat resistance
• D. Non-conductive property

Answer: (B)

The reinforcement’s job is to keep the hose from stretching under pressure. Polyester fibers provide high tensile strength with minimal elongation, so the 5 inch hose maintains its diameter as water is pumped. They’re also non-absorbent, which means the reinforcement won’t soak up water and add weight or alter flow. This combination—strong and resistant to expansion while staying non-absorbent—explains why polyester reinforcement is used. Increased flexibility might be a side effect, but it isn’t the defining reason; heat resistance and non-conductivity aren’t the primary benefits in this context.
