AC System Refrigeration Rubber Insulation Hose for Air Conditioner

 

Size	1/4" 3/8" 1/2" 5/8" 3/4" 7/8"
Work pressure	Max. 3.5 Mpa
Applicable temperature	-40ºC~+150ºC
Appliable refrigerant	R 134a/R 404a/R 410a ,etc.

1. For the applicability of refrigerants, R410a and R134a are both HFC refrigerants. Our company's rubber hose products are suitable for this type of refrigerant. The normal high-pressure working pressure of R410a is around 3MPa, which is slightly higher than the high-pressure working pressure of R134a. However, our company's rubber hose products have a minimum pressure resistance of over 15MPa, fully meeting the requirements for the use of this refrigerant;

2. The PAG and POE refrigeration oils used with refrigerants R410a and R134a are all synthetic oils, and our company's hose products of this type have good compatibility with this refrigeration oil; The final use of refrigeration oil in different equipment and applications should follow the recommendations of refrigeration compressor and refrigeration (air conditioning) equipment manufacturers, or determine the use of refrigeration machine lubricating oil with equivalent design and technical requirements based on the specific situation of the refrigeration compressor and refrigeration equipment, that is, choose equivalent refrigeration oil, For refrigerant R410a, the vast majority of compressor manufacturers recommend using polyol ester POE (Polyol Ester) refrigerant oil;
