Question: what is the difference between medium and heavy duty hoses?
Answer: Generally, light-duty hoses are three-ply, medium-duty hoses are four-ply and heavy duty hoses are five-ply, said Schneider Fouche, sales associate at a Home Depot. While a heavy-duty or commercial hose costs more than the others, it will stand up to abuse and is more likely to last longer, he said.
