NT118115

AIR LINE, 15' SET

This 15-foot rubber air line set (NT118115) includes a red emergency line and a blue service line, used to supply compressed air from a truck tractor to a trailer for braking and suspension. The tractor ends feature swivel fittings and spring guards for strain relief, while large color-coded grips make coupling and uncoupling easy. The rubber hose resists cracking, kinking, and weathering, fully meeting DOT FMVSS 571.106 and SAE J1402 standards. Replace these lines when they show signs of wear, leaks, or fail a DOT inspection to keep your braking system safe and compliant.
