Refrigerant and refrigeration oil filler

Refrigerant and refrigeration oil filler is a special device for replenishing media in refrigeration equipment. Its core advantage is "precise metering + leak-free filling". It adopts a brass valve body and fluororubber sealing components that are resistant to refrigerant corrosion, and integrates a high-precision graduated metering cylinder. The filling volume can be adjusted as needed. The one-way check valve design completely eliminates leakage and backflow of media, ensuring the cleanliness of the equipment's lubrication system and stable refrigeration performance. It is suitable for mainstream refrigerants such as R22 and R410A, as well as mineral oil and synthetic oil-based refrigeration oils, without the need for frequent replacement of accessories; the operating end is equipped with an anti-slip knob, and one person can complete the filling. Some models include a pressure warning function to avoid damage to the equipment due to overpressure. Applications cover household/commercial air conditioners, industrial refrigeration units, and cold storage equipment. Whether it is the filling of media during the commissioning of new machines or the replenishment of oil during maintenance, it can efficiently meet the needs and improve maintenance efficiency.
