R-22 and R-410A, while intended for the same type of appli- cations, are indeed very different refrigerants. Therefore, they cannot be mixed, and the equipment they are used in will be different.
What thread are refrigerant hoses?
Standard refrigeration charging hoses with 1/4″ SAE Male and Female Thread. Fit for R134a, R12, R22 refrigerants.
What size is R12 fitting?
The low-side R12 port is always 1/4″ male flare thread. While the high-side is usually the same size as the low, in certain applications it could be a smaller 3/16″ male flare.
What should my AC gauges read?
What are normal AC gauge pressures when the system is running? Generally speaking, you want around 27-psi on the low side and 200 on the high side.
What happens if you put 410A in a R-22 system?
If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.
Can I use car AC gauges on home AC?
No, they are not interchangable. The gauges are marked with specific temperatures and pressures that correspond to the refrigerant you’re using. You can’t check the charge on a home unit with an auto gauge set, and vice versa.
How many microns should a vacuum pump pull down to?
with a vacuum pump. Why a Vacuum Pump? ASHRAE recommends evacuation to below 1000 microns for moisture removal and below 500 microns after replacing a compressor. Some equipment manufacturers call for evacuation to 400 microns to ensure that harmful water vapor is removed from the system.
What color is the low side gauge?
Manufacturers color-code the hoses to distinguish between high pressure and low pressure. Low-side hoses are blue while the high side is red. The blue hose reading ranges from 0 to 99.9 psi while the red hose goes up to 999 psi.
What size are refrigerant hose fittings?
Co Elitech refrigerant charging hoses set with standard 1/4″ flare fittings.
What is the difference between the two ends of a refrigeration hose?
What is the difference between the two ends of a refrigeration hose? the manifold straight end does not have a core depressor and is connected to the gauge manifold. The crooked end has a core depressor and is connected to the service valve.
What SAE standard do refrigerant hoses go by?
Automotive Refrigerant Air-Conditioning Hose Requirements J3062_201506. The Scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid and gaseous R134a and/or R-1234yf refrigerant in automotive air-conditioning systems.
