The Zeagle Overpressure Relief Valve protects low-pressure hoses and second stages from overpressurization. It screws directly into any standard 3/8" low-pressure port on a first stage.
Standard intermediate regulator pressure is around 140 psi. If intermediate pressure exceeds 180 psi, this valve automatically vents the excess air.
