Air Hose End, Male Connector
Mack

The Air Hose End, Male Connector is a rugged fitting designed for secure, leak-free connections in air brake and pneumatic systems on heavy-duty trucks. Its male coupling geometry provides a reliable mating interface with corresponding female fittings, ensuring a tight seal under vibration and pressure fluctuations encountered on the road. The component is constructed from corrosion-resistant materials to withstand exposure to moisture, road salts, and temperature swings, which helps prevent binding and leakage over time. Quick-connect compatibility and robust threading simplify field assembly and service, reducing downtime during repairs or upgrades. This end fitting plays a critical role in protecting the integrity of air lines that control brake chambers, suspension, and auxiliary pneumatic systems. Source One Parts Center.
