CHARGING HOSE is a refrigeration system charging hose, which is a key component used to connect refrigeration systems, refrigerant cylinders, vacuum pumps and other equipment during the installation and maintenance of refrigeration equipment. The following is a detailed introduction:
1. Structure and material
Structure: It consists of an inner tube, a reinforcement layer and an outer protective layer. The inner tube is in direct contact with the refrigerant and needs to be resistant to chemical corrosion; the reinforcement layer provides strength and pressure resistance; the outer protective layer is wear-resistant and anti-aging.
Material: The inner tube is mostly made of nitrile rubber and other refrigerant corrosion-resistant materials; the reinforcement layer is often a steel wire or fiber braided layer; the outer protective layer is wear-resistant and weather-resistant rubber.

2. Functional characteristics
Strong pressure resistance: The working pressure can reach several hundred psi, and the bursting pressure is higher. For example, some products have a working pressure of 800PSI and a bursting pressure of 4000PSI, which ensures safe use in high-pressure environments.
Good corrosion resistance: It can withstand corrosion from a variety of refrigerants and refrigeration oils, extending its service life.
Good flexibility: It can be bent, which is convenient for operation in narrow spaces and equipment connection.
