If you trust the customer to set up the regulators properly then yes, it will be fine, but you'll still be over 100psi if doing only 2 tires on a high-flow compressor or if doing higher pressure tires without something limiting input pressure. As I mentioned above, the customer cannot be trusted to implement failsafes, you need to build them into your product to avoid court time.@LostWoods are you sure? If used properly and For its intended purpose with regulators set up properly I don’t see how you would get some kind of over pressure problem. Can the system be overloaded? Of course, just like everything else. Using the right tool for the job and some common sense goes a long way. Would a 150 psi hose make you feel better using a CO2 tank with far more pressure than that in it? They all need some kind of regulator.
