It's commonly used in heavy-duty truck and trailer air systems to route lines around tight corners while maintaining a reliable, leak-free seal. You'd replace this when upgrading to nylon tubing, repairing a damaged fitting, or reconfiguring air lines for brake chambers, valves, and suspension components. The brass construction with internal tube support provides durability and resistance to corrosion in under-vehicle environments.
