Color Coding (SAE J318)
Air-brake gladhands are color-coded by line. The blue gladhand is the service line — it controls trailer brakes during normal braking. The red gladhand is the emergency / supply line. Always connect blue-to-blue and red-to-red.
Sold individually. Includes rubber seal. Verify your existing gladhand port size (1/2 in NPT) before ordering.
