The wear and tear on gladhands through coupling and uncoupling increases the potential of loose air brake connections and accidental uncoupling that can lead to costly problems. To prevent this, Phillips Industries recommends changing gladhands every time the coiled air lines are changed. Phillips is pleased to now offer a complete line of Coiled Air Gladhand Assemblies. Gladhands are assembled to air coils at the factory, where thread seal is used along with proper torque, to ensure the best connection possible.
