Manifold gauge sets include: Manifold, 80 mm diameter pressure gauge, "Pulse free", Class 1.6, 3 x 1500mm pressure hoses, in a plastic carrying case. Rothenberger manifold sets consist of 80mm dial gauges with multi-coloured reading scales to allow easier and more accurate measurement. Rothenberger manifolds also include a refrigerant flow sight indicator, as well as specially designed knobs to allow smooth opening and closing of the valves, increasing product life. Rothenberger refrigerant manifold sets are designed to be robust and have greater resistance against knocks, due to the colour-coded rubber protection on each gauge. For R410A.
