EasyKlima Pressure gauge hose
A pressure gauge hose is necessary for refilling the A/C system. After connecting to the low pressure valve, it will measure and show the current pressure value.
It is reusable, and thus environmentally-friendly.
The hose comes with a user manual and diagnostic diagram.
Pressure gauge indications:
White colour range indicates that the system pressure is too low (less than 25 psi).
You should add refrigerant to the system until the gauge indicator is in the green range.
It is always recommend to use sealant first and then refill the system with gas.
Green colour range indicates the normal and recommended A/C system operating pressure (between 25 and 55 psi).
The level of gas in the system is correct. If pressure drops (the indicator moves to the white range), it is recommended to use the LeakStop sealant.
Red colour range indicates that the system pressure is too high (above 55 psi).
In this case, it is recommended to decrease system pressure.
