Air Brake Tubing, 1/2"OD

Air Brake Tubing, 1/2"OD 535Psi -50F to +200F

The 74203787 Air Brake Tubing (1/2" OD) is a high-performance nylon air line designed for heavy-duty air brake and pneumatic systems. Built from durable nylon material, this tubing provides excellent flexibility, pressure resistance, and temperature stability, making it ideal for demanding vehicle and equipment applications. With a maximum working pressure of 535 PSI and an operating temperature range from -50°F to +200°F, it performs reliably in both freezing winters and hot operating environments. In short, it’s the kind of air line that keeps air systems working properly instead of leaving you chasing leaks in the cold.
