The carbon steel construction with a 0.13-inch thickness provides resistance to corrosion and mechanical stress, supporting a maximum working pressure of 150 psi to meet rigorous braking demands.

Applications and Problem Solving

• Replaces worn or damaged air brake reservoirs on heavy-duty trucks
• Restores proper air storage capacity to maintain brake system performance
• Addresses air leaks caused by corrosion or physical damage to the tank
• Supports air brake systems requiring multiple port connections for air distribution
• Suitable for vehicles needing a 53-liter capacity air tank with specific port threading

Installation Notes and Tips

Ensure compatibility with your vehicle’s air brake system by verifying port thread sizes and mounting type. The Dorman 924-5814 requires strap-on mounting; confirm that your chassis frame can accommodate this style. Since mounting hardware is not included, source appropriate brackets and fasteners separately. Properly torque all port fittings to prevent air leaks and maintain system integrity. Inspect existing air lines and valves for wear during installation to ensure optimal brake system function.
