If a hose cannot be routed to avoid contact with a surface, what protection is recommended at the contact spot?

• A. Protective sleeve or hose guard
• B. Extra length to move contact point
• C. Sand the contact area
• D. Use a softer hose only

Answer: (A)

Main concept: when a hose must rub against a surface, protect the contact area. A protective sleeve or hose guard provides a durable buffer between the hose and the surface, preventing abrasion, cuts, and heat damage that could lead to leaks or a failure. It helps distribute the contact and reduces wear as the hose moves or vibrates. Other options don’t reliably prevent damage: adding length may shift the rub point but doesn’t stop wear; sanding the contact area or using a softer hose won’t prevent abrasion and can compromise safety. Use a properly sized guard or sleeve and secure it so it doesn’t kink or slip.
