1. Jinleng: a product of a central enterprise, the best refrigerant in the country, with the best quality, the most supporting facilities, and the price is also high.

2. Juhua: Zhejiang state-owned enterprise, the originator of the automotive refrigerant industry.

3. Dongyue: Shandong private enterprise, quality is acceptable.

These three are relatively formal companies with production capacity. Other brand products currently sold on the Internet do not have production capacity. You can just find a manufacturer to make a jar, randomly buy some raw materials, fill and sell them to make money. Quality cannot be guaranteed.

When purchasing, general refrigerants are dangerous goods and cannot be transported by express delivery according to national regulations. Therefore, regular manufacturers do not sell them online. It is recommended to inquire at auto parts stores and other places. Big brands will know it once you ask. .
