However, component replacement is not only for the winter months, it can apply all year round. Although not always necessary, it’s a good practice to replace air lines, and air line accessories, annually to ensure proper working order. However, during routine PMs, or during pre-trip inspections, if any of the following are noted, air lines should be replaced much sooner to avoid possible air line failures, leading to downtime, or CSA violations. • Chaffing or damaged jacketing • Rusted springs and/or fittings • Nylon cables that are stretched out and no longer recoil • Kinked nylon cables When selecting airlines for a tractor/trailer most know that it is recommended, and in some cases even required by law, to choose air lines with the following features: • Air line assemblies that display the appropriate markings which signify compliance with DOT regulations (Required by law) • Swivel fittings on the tractor end to avoid corkscrewing during installation • Spring guards; to protect the hose or tubing from a sharp bend at or near the fitting (Required by law) • Added handle grips at the trailer end to provide protection from kinking of air lines during gladhand connection and disconnection • Coiled assemblies that extend to their maximum expected service length and return to their retracted position without sag • Proper overall working length for the tractor-trailer application • If operating in harsh environments, use cables rated for extreme temperatures [Lower than the typical standard of -40°F (-40°C)] When installing new air lines its always important to remember the following: • If cables or handles are color coded, be sure to install/couple them with their correlating connections (red to red, blue to blue). • Always remove the old fitting from the tractor protection valve and install the new fitting attached to the new air lines. Damaged Jacketing, Rusted Springs • Air lines should be inspected regularly. It is suggested to replace them annually or upon discovery of damage to the air lines. • If cables or handles are color coded, be sure to install/couple them with their correlating connections (red to red, blue to blue). • Always remove the old fitting from the tractor protection valve and install the new fitting attached to the new air lines.
