In the description I see it only has one high-pressure outlet, but the model in question, the XL4+, has two outlets. Could you clarify this for me?

Hello. Yes, the specification states one HP port, but in reality there are two of them. The specification is incorrect. The regulator set is incredible! Best regards!
