Pressure Hose
Mack

This high-pressure hose is designed for demanding air or hydraulic circuits on Mack trucks, delivering reliable performance under elevated temperatures and flexing due to engine movement. It features a reinforced construction with layered braiding and inner lining designed to resist abrasion, oil, and coolant exposure while retaining flexibility in tight routing situations. The hose is tailored to maintain consistent pressure transmission, reducing the likelihood of dips in braking or steering assist that can affect vehicle control. Its fittings are engineered for secure, leak-free connections and easy serviceability during maintenance intervals. Correct routing, proper clamping, and avoidance of sharp bends are essential to maximize service life. In extreme duty cycles, regular inspection for cracking, coating wear, or hose softening helps prevent unexpected failures.
