What is the maximum psi for the MACK-1 air system?

Explanation:
Maximum pressure is about the highest safe pressure the system components are designed to handle. For the Mack-1 air system, the design specifies a limit of 125 psi because the regulator, hoses, and fittings are rated to that pressure. Staying at or below this ensures safe operation and prevents failures like leaks, regulator damage, or hose bursts. Pressures much higher than this would exceed what the components are rated to tolerate, making 125 psi the correct maximum. The other numbers would either be insufficient for proper operation or exceed the system’s rated limits, so they don’t fit.
