The Manual Nitrogen Changeover is a vital reliability component for nitrogenated beverage systems. This manifold allows you to connect two nitrogen tanks to a single supply line via two reinforced high-pressure hoses, enabling a rapid manual switch when one tank runs low. This ensures an uninterrupted supply of gas for nitro-coffee, stout, or wine-on-tap systems, preventing downtime during busy service shifts. Constructed from heavy-duty brass and industrial components for long-term commercial reliability.
