Negative Pressure Well Sealed Adapters Connectors Review

【Quick Coolant Replacement】You can perform coolant vacuum filling and cooling system pressure leak test with this coolant refill kit. The coolant vacuum refill kit generates vacuum in the cooling system by connecting the vacuum pump to suck the coolant into the radiator, which significantly shortens the time for coolant replacement, avoids air entering the radiator to cause poor coolant circulation, and reduces the risk of engine overheating. 【Accurate & Shock-proof High Negative Pressure Gauge】The coolant vacuum refill kit adopts a dual scale pressure gauge with a wide measuring range: -0.1~0 MPa, -760~0 mmHg. Its negative working pressure is up to 80kpa,which greatly improves the efficiency of replacing the coolant. The gauge head is covered with a rubber protective cover, which is shock-proof and has excellent stability and impact resistance.It can provide you with accurate pressure measurement and quickly detect water tank leaks. 【3 Adapters Fit for Most Vehicles】Cooling system vacuum purge & refill kit is equipped with 3 tapered adapters of different sizes(OD range: 0.63~1.3inch, 0.9~1.6inch, 1.34~2.05inch), which are widely suitable for coolant tank of most vehicles, like cars, SUVs, vans and trucks. You can choose the suitable adapter according to the size of the opening of the coolant tank. The adapters are made of superior rubber, which can effectively seal the cooling system. 【Well-sealed & Rust-proof Cooling System Refill Kit】Cooling system vacuum purge & refill kit is made of high-quality aluminum alloy and copper, which has high strength and can prevent rust and corrosion. Coolant leak detection kit has good sealing performance, prevents air leakage, and ensures the accuracy and reliability of the measurement. Note: Do not replace the coolant when the engine is hot. Please wear goggles and gloves during operation. 【Transparent Inlet/Outlet Hose & 2 Air Connectors】Coolant vacuum refill kit comes with a 40-inch inlet hose and a 20-inch outlet hose. The PVC hose is transparent, which is convenient for you to observe the coolant filling and draining. And the end of the inlet hose is equipped with a filter net to prevent impurities from entering the new coolant during filling. Vacuum coolant refill kit is also equipped with a American air connector and a European air connector to meet your different needs.
