Review ROBINAIR Manifold Gauge A/c Set New Old Stock

The Robin Air Cmn-4-2 Manifold Gauge A/C Set is a comprehensive tool designed to help diagnose and repair issues with automotive air conditioning systems. This set comes with two separate gauges, each serving a distinct function in the process of A/C system analysis.

The first gauge, labeled as a low side gauge, is designed to measure the pressure in the lower side of the refrigerant circuit. This side of the system typically contains the evaporator, compressor, and condenser. The low side gauge has a pressure range of 0-50 PSI and a temperature range of 32 F to 185 F. The large, easy-to-read dial is graduated in PSI and Fahrenheit, allowing for quick and accurate readings. The gauge also features a Schrader valve connection, making it simple to attach to the system.

The second gauge, labeled as a high side gauge, is intended for measuring the pressure in the high side of the refrigerant circuit. This side of the system usually includes the compressor, condenser, and pressure regulators. The high side gauge has a pressure range of 150-300 PSI and a temperature range of 60 F to 250 F. The dial on this gauge is also large and clear, with graduations for PSI and Fahrenheit. It comes equipped with a Schrader valve connection as well.

Both gauges are connected to the air conditioning system via the Schrader valve stems, and the set includes a pair of adapters to accommodate various vehicle makes and models. The robust construction of the gauges ensures durability, with impact-resistant cases and sturdy metal components that can withstand the rigors of automotive use.

In summary, the Robin Air Cmn-4-2 Manifold Gauge A/C Set is an essential tool for anyone working on automotive air conditioning systems. With its two separate gauges, each designed for measuring pressure on the low and high sides of the refrigerant circuit, this set offers the versatility and accuracy needed to diagnose and repair A/C issues effectively. The sturdy construction and included adapters make it a valuable addition to any automotive workshop.
