Black Diamond’s ball valve manifold gauges are engineered for speed, with our unique full-flow port design. This provides a larger, unrestricted path for refrigerant compared to traditional piston valves which results in significantly faster evacuation and charging times.
The ergonomic “quarter-turn handles” go from fully closed to fully open with a quick 90° rotation, offering immediate response and easy control. Housed in a durable, anodized aluminum body and with a large sight glass, these gauges are the best choice for technicians who prioritize speed and performance.
