Its job is to maintain a tight, leak-free seal in the air lines that supply the service and emergency brakes. Over time, heat, dirt, and repeated coupling cause seals to crack or deform, leading to air leaks that can reduce braking performance or cause a brake system failure. Replacing worn gladhand seals is a routine, low-cost maintenance step that keeps the brake air system safe and reliable.
