Robust and : Featuring a plastic oil barrel, copper connector, PU oil pipe, and stainless steel adapter with a plastic-sprayed finish, this product has good resistance to rust, corrosion, aging, wear, and impact, ensuring a long service life. Double Action: The consistent changeover between the blue screw valve and the air inlet ball valve allows for the double operation of oil extracting and dispensing to increase your efficiency. Safety Protection: The safety valve allows automatic pressure relief after the pressure reaches 8 bar to prevent explosion and ensure safety. Meanwhile, the pressure meter allows you to easily understand and control the pressure in the barrel. User-friendly Design: The oil outlet pipe and oil suction pipe can be directly inserted into the oil tank or dipstick tube of the vehicle to extract or refill transmission oil without jacking up the vehicle or crawling under it for work. The buckle on the handle can lock the trigger for a long time to reduce work fatigue. Thoughtful Design: The quick-plug connector allows you to connect quickly with just one simple snap. When not in use, it can lock the valve to avoid oil leakage., Manufacturer: HEALBYBLE
