The Star Product: Mastercool Manifold Gauge Set 

I. What is a Manifold Gauge?

A manifold HVAC gauge is an important measuring tool to check the pressure in an air conditioner or a refrigerator. This will help to determine any presence of leaks. Any form of recharge or evacuation in the machine may also be necessary. Its function is not only limited to cooling but it does have use in heating and ventilation as well. Aside from checking the pressure, it also helps in transferring refrigerants and to get rid of the nitrogen in the system. The manifold HVAC gauge has a low-pressure valve and a high-pressure valve. On both sides of the valves is a compound gauge. This gauge is commonly expected to be readily available and always carried by any technicians working in heating, ventilation and air conditioning.
