What type of fitting is used to join the ends of a tube when repairing hydraulic tubing?

The use of a swaged tube fitting to join the ends of a tube in hydraulic tubing repair is essential due to its strong and reliable connection. A swaged fitting is permanently deformed around the tube, creating a secure and leak-proof seal that can withstand high pressures typically found in hydraulic systems. This method enhances the integrity of the connection, ensuring safety and functionality in hydraulic applications.

In contrast, other fitting types serve different purposes. Compression fittings can be used for connections but are not generally recommended for high-pressure applications due to their potential to loosen under such conditions. Screw fittings also do not provide the permanent, robust connection that swaged fittings do, making them less suitable for hydraulic tubing repairs. Quick disconnect fittings, while convenient for making temporary connections, do not offer the necessary durability and resistance to high pressures expected in hydraulic systems. Therefore, swaged tube fittings are the best choice for ensuring a secure and effective repair in hydraulic tubing.
