Gladhand basics
- Gladhands couple by rotating the two heads together. A rubber seal in each head holds the air pressure.
- Service (control) and emergency (supply) lines are typically color-coded blue and red so they don't get crossed.
- Replace the seal or the gladhand if you hear air leaking at the coupling or see cracked or flattened rubber.
