Manifold for R404A, R134a, Refrigerator, Showcase and Ice Maker: The scale is clean and easy to read. This is a manifold that can be used with both heating and cooling conditions, so the pressure value of the low pressure side pressure gauge has been set to high pressure, so that you can measure the operating pressure when heatering. The gauge of the gauge manifold kit is made with high precision, certificate of inspection (lot certification). Image uses TA124E.
