Manifold gauge kits, sometimes referred to as HVAC gauges or refrigeration gauges, diagnose and repair refrigerators or refrigeration systems. They measure both low and high refrigerant pressure using either digital or mechanical gauges to troubleshoot problems such as leaks or to help evacuate and refill a system.
Manometers are used to monitor heating or cooling systems, especially the pressure of refrigerants. These tools are used to control the flow of pressure or gas. HVAC test tools can be either small handheld devices or larger machines used in a professional HVAC shop.
It consists of three chamber devices; Low pressure chamber, high pressure chamber and utility chamber. These chambers allow gas flow and pressure to be controlled. These are critical to the fundamental performance of HVAC gauges.
Pressure gauges are used to read the pressure of various liquids and gases in a refrigeration system, as well as vacuum pressure when testing or charging the device.
A manifold gauge set consists of a manifold block, two manual valves, three refrigerant hoses and two gauges.
No, they are not interchangeable. Gauges are labeled with specific temperatures and pressures that correspond to the refrigerant you are using. You cannot check the charge on a home unit with an automatic meter and vice versa.
Every car air conditioner has two service connections: one on the high pressure side and one on the low pressure side. When topping up with AC Avalanche refrigerant, fill through the service port on the low-side for safety reasons. Never load through the high-side port.
This central distributor has either three or four connections. For the three-port manifold, the blue hose connects to the low-pressure vapor port, the yellow hose to the middle port for recovery or fill, and the red hose to the high-pressure liquid port.
Manifold Valve Function
A manifold is a device that connects one or more isolation/isolation valves of a hydraulic system. Valves of a hydraulic system can include ball, needle, bleed and bleed valves.
High pressure gauge (high side)
The high pressure gauge is used to determine the pressure on the high side of the system.
