Made in the USA and the quality shows. This is the best regulator I've ever had. If I set it to 55psi, the output pressure stays the same when the tank pressure is 55 or higher with no air flow. The wide open exhaust airflow lowers it by about 5 psi. All the regulators I've used in the past have had very different set pressures, dropping 20psi at high airflow and rising 20psi at pressure. in the tank rises.
