It replaces cracked, torn, or dried‑out rubber seals on the emergency (supply) side gladhand coupling, restoring an air‑tight connection between tractor and trailer. Mechanics replace these seals when they become hard, deformed, or cause air leaks, which can lead to brake system pressure loss. The polyurethane material resists oil, chemicals, and ozone, and the red color follows industry color‑coding for the emergency line.
