KINKS
Kinks in your air lines restrict and reduce air flow, affecting brake performance. Common spots to find kinks include the point at which the line is suspended as well as under the spring near the fitting on the gladhand end. Lines that are equipped with a handle or grip are less likely to kink.

CUTS, CRACKS & WEAR
Inspect the full length of your coiled air tubing for cuts, cracks, and wear. As coiled air assemblies age, the color will fade and the material becomes brittle. Hairline cracks are common and a clear indication that the air line needs to be replaced.

SAG, DRAG & SNAG
In most cases, a tracker bar and spring is needed to support your air and electrical lines above the deck plate to prevent damage from snagging and chafing. Excessive sagging is a clear sign of worn out lines. Be careful in winter because sagging lines can also collect water and freeze!

TANGLES
Tangled up air lines have a reduced working length and are the most common cause of breakaway failures. Your air lines need to maintain free movement so the full length can be during tight turns.
