We purchased Many New and some used Regulators from a Business Closing sale. This Regulator was labeled NEW just not in it's factory Box. Our Savings will be passed onto you. This has an outlet Valve to shut off the gas pressure. The Inlet Fitting Nut has 330M stamped on it(that can be changed if needed). Look this regulator over and do any research you need to make sure what you purchase is right for you. We will accept returns but buyer will be responsible for all shipping costs.
