The Secondary Pass-Thru CO2 Regulator is a precision gas management component designed for multi-tap draught systems. This unit features a 0-60 PSI output gauge, allowing you to independently manage the pressure for a single keg while passing gas through to other regulators in a series. It includes a 1/4" Male Flare (MFL) outlet with an integrated one-way check valve, which prevents liquid backflow from the keg into the regulator internals. Built with a heavy-duty body for professional reliability in high-volume environments.
