This Sealey Vacuum Oil and Fluid Extractor (Model: S01169) is an ingenious vacuum device with a 6.5L capacity, ideal for extracting engine oil and other liquids such as water and soluble oil. It comes supplied with Ø4mm, Ø6mm, and Ø8mm suction probes, along with a Ø10mm x 1m extension tube. The probes can be conveniently stored in the holder on the unit when not in use. To extract oil from a car engine, simply insert the probe down the dipstick hole and operate the handle on top of the unit. This allows for permanent fluid transfer, eliminating the need to search for drain plug keys or get under the vehicle, making it perfect for mobile mechanics. The pump builds pressure within the housing to withdraw fluid and features an internal valve that cuts off when full, preventing overflow. It is easy to empty and is not to be used with petrol.
