A gas charging line, or refrigerant charging line, is a flexible hose used to connect a refrigerant cylinder to an AC system for the purpose of adding or removing refrigerant gas. These lines are typically color-coded (blue for low pressure, red for high pressure) to help technicians avoid errors when connecting to the correct ports on the AC unit.

In fact, copper pipe fittings are mainly used with copper pipes used for supplying hot and cold water in residential water supply lines, as refrigerant line in HVAC, etc.

K copper tube type is excellent for outdoor and underground plumbing, HVAC, and refrigeration applications where strength and durability are essential. It can also tolerate higher internal water pressures better than L copper.

R290 and R32 are both gases used in air conditioning units. They're also known as refrigerants, which means they help cool down your room by turning into liquids when pumped through the system.

Air conditioners commonly use refrigerants like R-32, R-410A, and R-22. R-32 is a hydrofluorocarbon (HFC) refrigerant with a lower global warming potential than R-410A, while R-410A is another HFC refrigerant widely used in modern AC units. R-22 is a hydrochlorofluorocarbon (HCFC) refrigerant, which is being phased out due to its ozone depletion potential.
