A vacuum gauge is an indispensable tool for every installer, before filling the cooling system with refrigerant, ensuring that the system is completely free of air and moisture and preventing refrigerant leakage or loss of efficiency. A vacuum gauge helps ensure that your system operates optimally and reliably even in the most challenging conditions.
