Vacuum Type Quick Coolant RefillThe airlift coolant refill tool adopts vacuum filling. In a vacuum state, the coolant can flow fully, effectively removing air and impurities from the radiator system, and ensuring the stable operation of the radiator system. There is no need for time consuming airbleeding, and the coolant can be filled in a short time, improving work efficiency. Prevent the engine from overheating or overcooling and ensures that the engine operates at a normal working temperature. Universal Cone Adapter Wide ApplicationOur coolant vacuum fill tool is equipped with a universal rubber conical adapter. The conical adapter has a small contact area and provides good sealing performance, being suitable for most car models. The coolant system refiller kit is also equipped with 4 rubber adapters of different sizes OD 1.41, 1.53, 1.73, 2.16 to ensure compatibility with radiator necks of various dimensions. It is widely applicable to automobiles, vans, and light duty trucks, etc., making it an ideal choice for most vehicles. Precise Flow Control Quick Vacuum Tee FittingThe vacuum coolant refill tool is equipped with a pressure gauge with a rubber casing. It is impact resistant, dropproof, and durable. The screen is not easily scratched, keeping the readings clear. The scale range of the pressure gauge is 10 Bar760 cmHg, which can monitor the tank pressure in realtime to ensure accurate coolant filling and complete the supply of the radiator system efficiently and accurately. The vacuum coolant refill kit is also equipped with a brass tee fitting for quick installation, enabling faster vacuum extraction,effective coolant distribution and regulation, and improving the efficiency of coolant filling. QuickConnect Brass Interface 41.3Inch Thickened Transparent HoseThe auto coolant vacuum refill kit has a hose connection port made of excellent brass, and the main body is made of aluminum alloy, which has high hardness and corrosion resistance. It can be quickly connected with tee fitting and hoses, saving refill time. The thickened transparent hose for coolant filling is 41.3 inches long, featuring corrosion resistance, abrasion resistance, and pressure resistance. It has good sealing performance with no leakage, maintaining a long service life. The other end of the hose is equipped with a filter, which can filter impurities to ensure the replenishment of clean coolant. Easy To Use StoreUse the vacuum purge coolant refill tool set to connect to the vehicles coolant tank, then connect the air compressornot included to draw the vacuum, and the pressure reaches 5060cmHg, connect the vacuum coolant fill kit hose, the hose connector is completely submerged in the coolant level, open the valve, and the coolant will automatically replenish the coolant tank. The coolant system refiller kit includes a thick blowmolded case, it is lightweight, impact resistant, convenient for carrying and transportation, safer storage, and can firmly fix all components in place, ready for your next project.
