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.

R32 is a HFC refrigerant, used as a replacement for R410A in low temperature refrigeration and air-conditioning applications. This refrigerant is a preferred replacement for R410A in new equipment. R32 is not to be used as a retrofit.

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.

Air conditioners typically use refrigerants like R-410A or R-32, which are Hydrofluorocarbons (HFCs). R-410A is commonly used, while R-32 is gaining popularity due to its lower Global Warming Potential, according to Bajaj Finserv and FreQuip Rentals. Older ACs might use R-22, also known as Freon.

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.

Rubber Sleeve: A Rubber Sleeve is a basic type of coupling. This consists of a pipe whose bore is finished to the required tolerance based on the shaft size. Rubber Sleeves and buffers can be manufactured in a range of shapes, sizes and material to suit the application.
