It includes two color-coded nylon hoses—red for the emergency (supply) line and blue for the service (control) line—with permanently swaged 1/2-inch NPT fittings and protective spring guards. The coiled design helps keep the lines off the deck and prevents kinking or dragging. Replace the set when the tubing shows cracks, chafing, or air leaks to maintain safe braking performance.
