Which statement concerning flexible hoses is false?

Which statement concerning flexible hoses is false?

• A. They never require replacement
• B. They are rated for specific pressures and temperatures
• C. They should be inspected for wear and damage
• D. They should be installed with proper clamps to prevent movement

Answer: (A)

Flexible hoses are designed to handle defined pressures and temperatures and have a finite service life. They should be regularly inspected for wear, cracking, abrasion, swelling, or leaks, especially around fittings and bend areas. Proper clamps are essential to prevent movement, which can cause fatigue and failure at the hose ends. The statement that they never require replacement is not accurate because hoses age and degrade from heat, vibration, chemical exposure, and repeated bending. Over time the reinforcing can weaken, leading to leaks or bursts. Replace hoses when there are signs of wear or aging, or after the manufacturer’s recommended service life, and always ensure the hose is suitable for the specific fluid and operating conditions.
