Will an automotive A/C gauge manifold work for a house A/C system? no it is not.
These are our recommendations for the best manifold gauges:
- Mountain 8205 R-134a Brass Manifold Gauge Set with Couplers.
- Robinair 48510 R134a Aluminum Manifold Set with 72″ Hoses.
- Yellow Jacket 42006 Series 41 Manifold.

Keeping this in consideration, can you use the same gauges for r22 and r410a?
No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.
What should the high and low side pressures be?
Actual readings will vary according to ambient temperature. The low–side should be near 30 PSI at 90 degrees Fahrenheit or less. Pressure that is too much lower or higher shows there is a problem. On a properly working system, high–side pressure will be about twice the ambient temperature, plus 50 PSI.
What should AC manifold gauges read?
The gauges readings will depend on the ambient temperature. With the A/C turned OFF – On a cold day the pressure will be low, on a hot day the pressure will be high. COMPRESSOR TYPE. AMBIENT TEMP RED GAUGE (PSI) BLUE GAUGE (PSI) 10 40-60 20-30 20 60-120 20-30 30 120-150 25-35 40 150-180 25-35
Can you use r134a gauges on r22?
R134A is typically used in automotive/small appliance applications. Assuming you are talking about a “room air conditioner”, the correct up to date refrigerant is R410a. You can use any gauges you like to check the pressure of the system, with slight risk of cross contamination.
How do you hook up manifold gauges?
How to Hook Up & Read HVAC Gauges Connect the high pressure side of the cooling line to the red port on the gauge. Connect the low pressure side to the blue port on the gauge. Attach a waste hose or vent hose to the center of the manifold set up. Attach micron meters or other gauges to the additional ports.
What is a manifold in HVAC?
GAUGE MANIFOLD This component has a double-pronged purpose as a diagnosis and service equipment. It consists of three chamber devices; low-pressure chamber, high-pressure chamber, and utility chamber. These chambers provide control over the flow of gas and pressure. These are crucial for HVAC gauges basic performance.
What is the best refrigerant?
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.
Why is refrigerant not used for a standing pressure test?
*Why is refrigerant not used for a system standing pressure test? Because of temperature relationship (illegal to vent refrigerant into atmosphere). A pressure of 100 microns has been reached with the vacuum pump operating. The pump is turned off and the gauge reading rises to 500 microns and stays there.
What can cause a gauge line to leak?
A gauge line can leak due to a simple break. it may also be caused from a line tearing away from the plug. the gauge itself may also be too large or too small for the plug as well.
What range is displayed on a high pressure gauge on a service manifold?
A high-pressure gauge at the right side of the manifold is used to measure system high-side (discharge) pressures. It is typically calibrated to measure system pressures in the range of 0 to 500 psig.
