A hydraulic tubing damaged in a localized area may be repaired by which method?

• A. Replacing the entire length
• B. Welding the damaged area
• C. Cutting out the damaged area and using a swaged tube fitting to join the tube ends
• D. Using a clamp repair

Answer: (C)

When hydraulic tubing has a localized damaged area, the repair should restore a smooth, uninterrupted flow path and a joint that is rated for high pressure. Cutting out the damaged portion and joining the tube ends with a swaged tube fitting achieves this by removing the compromised section and using a fitting designed to seal and hold the tube ends tight under pressure. This method preserves the tube’s strength and bore, avoids introducing heat-affected zones that welding would create, and provides a reliable, permanent connection appropriate for hydraulic systems. Replacing the entire length is usually unnecessary for a small defect, welding is generally avoided on hydraulic lines due to potential weakening from heat, and clamp repairs are not considered a durable, high-pressure solution.
