The Yellow JacketÂ® Series 41 two-valve manifold for R-22, R-404A, and R-410A now has larger, easier-to-read, 3-1/8-inch color-coded gauge dials with cases made of rugged steel and polycarbonate crystals. The refrigerant scales and pressure arcs are color-coded. According to the manufacturer, surge protection and silicon dampened movement provided by Flutterlessâ„¢ technology minimize needle pulsation for easier, more accurate readings. Other features include sliding double O-ring pistons to reduce wear, long-life nylon seats, full porting to maximize capacity and flow, and full-size metal valve handles for easy operation, the company says.
