Tube
Mack

A versatile tubular component used to convey fluids, gasses, or control signals within various truck subsystems. This generic tube supports applications ranging from cooling lines to plumbing within the chassis, offering predictable flow characteristics when correctly sized for pressure, temperature, and chemical exposure. Tubing choices influence system efficiency, with wall thickness and material composition driving durability against wear and environmental stressors. Proper routing, secure mounting, and compatible fittings ensure leak-free operation and minimize vibration-induced wear. In maintenance scenarios, tube replacement can restore performance when old lines become brittle, corroded, or cracked. The part’s universality makes it a common reference in service manuals and repair orders. Source One Parts Center notes its role as a core element in fluid and air conveyance networks across multiple truck platforms.
