The introduction of rubber conditioner hose SAE J2064

This piece aims to let you know about rubber conditioner hose SAE J2064. The rubber conditioner hose SAE J2064 is widely used in vehicles’ air conditioner systems to convey R134a and R12 refrigerants. The rubber conditioner hose SAE J2064 is designed to minimize the permeation and leakage of the R134a and R12 refrigerants. This rubber conditioner hoses’ working temperature ranged from -40 ℃ to 135 ℃. The basic construction of SAE J2064 rubber air conditioner hose contains CSM/EPDM tube, nylon alloy barrier, EPDM/NBR buffer, PVA reinforcement, and EPDM cover.The construction details of this hose can be discussed by the buyers and manufacturers. The hose marked ‘SAE J2064’ represents the hoses have met the requirements of SAE J2064 for R134a refrigerant.

Why is the rubber conditioner hose hot in use?

Indeed, it is normal for the high-pressure automobile air conditioner hoses to be hot while in use. Because the refrigerant in the tube has just been compressed by the compressor, the refrigerant here should be in a high temperature and high pressure state, which can be known according to the working principle of the car air conditioner. Therefore, it is normal for the high-pressure automobile air conditioner hose to be hot.

What is the reason for the icing of automobile air-conditioning hoses?

If we say the phenomenon of the automobile air conditioner hoses to be hot in use is normal, but the icing is not normal. The reasons for the icing of automobile air-conditioning hoses might be blockage of the air-conditioning drain hole, high water content of the refrigerant in the air-conditioning system, failure of the evaporator temperature sensor, and blockage of the expansion valve, etc. The icing of the automobile air-conditioning pipes will affect the refrigeration of the automobile air-conditioning. You should go to the repair shop for inspection and maintenance in time.
